Product Description
LX Type Elastic Pin Coupling (GB/T5014-2003)
LX Elastic pin coupling is made of several non-metallic elastic pins and 2 half couplings. The coupling is connected by lacing these elastic pins into holes of 2 half couplings, and thus the torque is transferred.
LX Elastic pin coupling can compensate the relative offset of 2 axes to a certain extent. Elastic parts are sheared during operation and are generally applicable to the working conditions of medium speed transmission shafts with low requirements. Allowable working temperature environment temperature is -20ºC~+70ºC, the nominal transfer torque is 250~180000N.m.

What Is a PTO Shaft?
There are a few different types of PTO shafts. For example, there are German, Italian, and North American types. Moreover, there are several series options, such as cap-to-cap overall length, bearing diameter, and snap rings. Each type comes with different features and benefits, so it is important to select the correct one for your needs.
Power Take-Off
The Power Take-Off (PTO) shaft is a mechanical coupling system that couples an aircraft’s accessory gear box with an engine. It transmits high rpm and peak torque. It is an indigenously developed product, which has been cleared for flight fitment and successfully completed an engine ground run test. It is now being used by two Indian manufacturers.
There are four main types of PTOs. Semi-permanently mounted power take-offs are common on marine engines and industrial engines. These power take-offs are used to power secondary implements and accessories. In airplanes, accessory drives are also common. Jet aircraft use four different types of PTO units:
PTO shafts are composed of two telescoping pieces that slide into one another. This allows the user to lower and lift the implement. They are also equipped with universal joints, also known as U-joints. These joints allow flexibility and durability. These joints are held together by two yokes at each end of the shaft.
The speed of the power take-off shaft varies according to tractor size. Larger tractors turn the shaft at 1,000 revolutions per minute, while smaller tractors turn it at 540 revolutions per minute. This means that a person trapped in the open PTO shaft could be whipped around nine times in one second, while a person caught in a smaller tractor could be whipped around 16 2/3 times in one minute. Ultimately, the weight of the person could even cause the engine to stall.
Applications
PTO shafts have a variety of uses in the farm equipment industry. They can be connected to a wide variety of work equipment. For instance, a PTO is commonly used to power a hydraulic pump on a tractor’s front end. In such a case, a small shaft with a U-jointed design will attach to a yoke coupler and turn the pump. While this is not as universal as a tractor PTO, it still falls under the category of a PTO.
A PTO system will have a female coupling on one end and a male coupling on the other end. This essentially acts as an extension adaptor. It will transmit torque signals from the shaft to a static cover assembly to determine the speed and torque in both directions. In some cases, a PTO system will be able to record the data directly onto a PC or other electronic device.
In addition to power take-off systems, these systems can also provide power for auxiliary equipment. In addition, a split shaft PTO allows the power of one engine to power the axle of another vehicle. Depending on the engine’s power, a PTO may use either an air or hydraulic pump to power auxiliary equipment.
The PTO shaft is also useful for securing a tractor or equipment. This device features safety shields on both ends and fits securely inside the secondary shaft. The PTO shaft can be found in a variety of shapes. There are domestic-shaped and metric-shaped versions.
Safety precautions
Operator awareness is key in preventing PTO shaft entanglement. It is important to avoid performing any repairs while the machine is operating. It is also important to avoid wearing loose or frayed clothing that could become entangled in the rotating shaft. It is also essential to read and follow the tractor’s operating manual. Also, ensure that the PTO shaft is only used for its intended purpose.
A power take-off, or PTO, is a type of attachment that transmits mechanical power from a tractor to another piece of farm machinery. Common examples include hay balers, rotary cutters, weed mowers, and forage blowers. These attachments are often equipped with protective shields to prevent entanglement. The shaft should always be covered when in use.
Operators should also avoid getting too close to the PTO shaft. The operator may become entangled if they accidentally approach the spinning shaft. They should also avoid wearing loose clothing because loose clothing can easily get caught in the stub and cause serious injury. These safety precautions are essential for safe operation of all farm machinery.
When using a PTO with heavy drive, it is important to use a heavy-duty model with a PTO shaft that is appropriate for the application. Alternatively, use a universal joint or wide-angle universal joint. These attachments can be a safer alternative to traditional PTOs. Draw-bar pins on trailed machines should be firmly secured to avoid damaging the PTO shaft. It is also recommended to guard all drive shafts on the machine.
Design
A PTO shaft has several advantages. It is a versatile power transmission that is ideal for heavy-duty equipment. Its design is rigid, yet flexible, allowing for high-speed operation. This is due in part to the splines, which prevent the parts from separating during operation.
The gears of a PTO drive are made from high-quality steel, which increases their durability. They are made from SCM 440 gear material. This material has a high tensile strength and a high yield point. It also has a high Young’s modulus of 206,000 N/mm2. Its Poisson’s ratio is 0.3, while its pressure angle is twenty degrees. In addition, its addendum and dedendum coefficients are both greater than 1.0.
Designed for use on industrial and marine engines, PTOs allow the driver to transfer power from a primary mover to a PTO-powered attachment. They are easy to install and offer improved service life and decreased downtime. In aircraft applications, PTOs are also common. Jet aircraft and agricultural equipment often use PTOs.
The PTO shaft’s dimensions are crucial for preventing vibration. It should extend at least 14 inches from the hitch point to the input shaft of the implement. In some cases, a shorter shaft may not fit the tractor, so it is important to choose the right size. If the PTO shaft is too short, it could cause the two parts to separate when the tractor is turning a corner.
Cost
A PTO shaft is a very important part of a tractor because it transfers power to an attached attachment. These attachments typically include rotary tillers, brush cutters, hush hug, and mowers. While many attachments use a PTO shaft, the connection flange is not standardized. Some older models of tractors may have a connection flange that is closer to the tractor.
A PTO shaft will work with either a standard or a Weasler yoke. You can also choose from metric and North American models. There are also Italian PTO shafts. To ensure the best performance and durability, it is essential to ensure that the shaft is free of damage. To avoid such damage, a PTO shaft should be purchased from a reputable supplier.
PTO shafts are made from high-quality steel and feature a 1-3/8″ 6-spline at both the tractor and the implement end. In addition, splined PTO shafts are easy to replace and provide excellent horsepower. These PTO shafts can also increase a tractor’s work efficiency.
The cost of a PTO shaft replacement can vary. The average price range for a front-wheel-drive half-shaft is $470 to $940, and the cost for a rear-wheel-drive drive half-shaft replacement is about $1,600 to $2,000. The parts cost about two hundred dollars and the labor could take an hour or more.
Buying guide
If you’re looking to replace a PTO shaft on a lawn tractor, it’s important to consider several factors. First, the PTO shaft needs to be compatible with the tractor you plan to use it on. Then, you need to determine which size universal joint you need. To do this, you can use a PTO shaft size chart.
The PTO shaft is the component that transfers power from the tractor to the attached implement. It’s made up of several parts, including the internal and external PTO yoke, the universal joint, and the safety chain and shield. There are several types of PTO shafts available. You’ll want to choose the right size for your machine, as well as the number of PTO shafts you need.
A PTO shaft is essential for a tractor because without it, the tractor cannot drive. Understanding the PTO parts will help you operate farm machinery more effectively. For instance, if you’re buying a new Power Take Off shaft, you’ll want to look for one that’s compatible with the model and year of the tractor.
You’ll also need to consider the length of the PTO shaft. A PTO shaft can vary from 53 inches when compressed to 77 inches when fully extended. The most common length for a PTO shaft is about fifty-three inches, but you can also choose a longer one if you need more flexibility.
