Introduction
If you’re in agricultural or industrial machinery, you might be familiar with the term “PTO yoke”. It is an essential part of any equipment that relies on power take-off. In this article, we will specifically focus on the 21 spline pto yoke - what it is, how it works, and what benefits it offers.
What is a PTO Yoke?
A PTO yoke is an interface between the machine’s power take-off shaft and the driven implement. It typically comprises two parts - a yoke with external splines that attaches to the PTO shaft and a corresponding inner yoke with internal splines that attach to the implement’s input shaft. Together, they transmit rotational power from the PTO to the implement.
Understanding 21 Spline PTO Yoke
21 Spline PTO Yoke is a type of PTO yoke that has 21 splines on the external and internal yoke. The type of spline, i.e., the number of teeth, determines the torque capacity of the PTO yoke. The higher the number of splines, the greater the torque it can handle.
Compatibility
It’s crucial to ensure that the PTO yoke matches the specifications of the twisting force and the size of the shafts. The standard size of the PTO shaft in North America is 1-3/8 inches, and the yoke size generally ranges from 1-3/8 to 1-3/4 inches. However, there are exceptions where PTOs may have different shaft sizes, which necessitate the use of the right sized yoke.
Benefits of 21 Spline PTO Yoke
21 Spline PTO Yoke offers several benefits, which include:
- Increase in the torque capacity - the 21 spline configuration of the PTO yoke provides a higher torque capacity than PTO yokes with fewer splines.
- Stronger grip - since there are more splines, the grip between the PTO shaft and the yoke is stronger, leading to an improved performance.
- Lower vibration - the 21 spline configuration minimizes vibration by distributing the torque load evenly.
- Longer lifespan - the PTO yoke's increased durability ensures an extended lifespan, reducing the need for frequent replacements.
Installation and Maintenance
Installation and maintenance are essential to prolong the PTO yoke's lifespan and avoid any failures. Always check the manufacturer's instructions to make sure you have the correct specifications before installing a 21 Spline PTO Yoke. Proper greasing, torque, and alignment are critical factors that ensure the PTO yoke's optimal performance.
Where to Buy
21 Spline PTO yokes are available from several online and offline retailers, including tractor supply stores and industrial equipment dealers. Be sure to check the specifications and compatibility before purchasing a PTO yoke.
Conclusion
21 Spline PTO Yoke is an essential component of machinery that requires power take-off, including agricultural and industrial equipment. Utilizing the 21 splines configuration provides several benefits - higher torque capacity, stronger grip, lower vibration, and extended lifespan. It’s essential to ensure compatibility, proper installation, and maintenance to ensure optimal performance.
