Related QD Bushings | Quick Disconnect Bushings

QD bushings are utilized throughout the industrial power transmission and agricultural industry for various sprockets, sheaves, pulleys, and synchronized drives. They are designed for easy installation and easy uninstallation; they are also commonly referred to as quick-disconnect bushings. QD bushings can help conventional mounting with the flange outboard and reverse mounting to where the flange is inboard and utilize a single split that extends through the entire bushing length. Our QD bushings interchange with other brands and are made from high-grade steel precision machined for perfect application fitment. QD bushings' benefits over different styles include; ease of installation/ uninstall, superior holding power, and extreme strengths. We stock all the standard sizes of QD bushings and supply custom QD bushings upon request, including stainless steel ones. QD bushings are found in some of the most rugged applications worldwide; contact our customer service team today for a quote or additional information on our premium QD bushings.

How to Avoid the Problem of Over-tightening the Pulley?

Many customers are very trying in the process of disassembling the pulley, so the disassembly process is easy to damage the pulley, which is often caused by the over-tightening of the pulley, and the over-tightening of the pulley will easily affect the regular operation of the equipment, so how can we avoid the problem of over-tightening the pulley?

To solve the problem that the shaft and the pulley are too tight, it is recommended to start from the following two aspects:

1. Do not install the key first; use an emery cloth to remove the burrs and rust on the groove surface, use a file to repair the file when the burr is serious, and then install the pulley on the shaft without installing the key. Check the shaft diameter and wheel hole if it is very tight or cannot be installed. If the motor shaft is large, you can turn on the power to make the motor rotate and press it against the rotating shaft with an emery cloth (pay attention to safety), which is easy for repair electricians. Do it. In this way, the trimming will not produce an ellipse; it will save effort and then try to install it. Apply lubricating oil on the shaft each time you want to install it. The v belt pulley can be pushed in by hand or lightly driven with a hammer, but it cannot feel loose.

2. Measure the depth of the keyway. This dimension should be larger than the thickness of the key. Otherwise, the thickness of the key should be thinned until the gap between the key and the bottom of the hub groove depends on the size of the shaft. Generally, 0.2~0.6mm (check the critical standard), put the key into the wheel hub, and it should be able to slide slightly loosely. If not, repair the burr or find the reason to fix it, then gently drive the key into the shaft groove with a hammer. The key needs to be replaced. And evenly apply lubricating oil on the pulley hole, shaft, and critical during assembly.

What Are the Pulleys Used For?

The pulley is not only used on the car; it is mainly used to transmit power over long distances. It has many applications, such as the power output of small diesel engines, such as tractors, cars, etc. It is also used in mechanical transmissions, such as machining equipment, textile machinery, lathes, and forging machines.
