Expansion Coupling Sleeve Type ZJ8
Description
Expansion bushings, also known as keyless bushings, are friction-connected tools that convert the tightening force of a bolted connection into surface pressure on the side of the inner diameter through the taper. It converts the tightening force of the bolt connection into surface pressure on the side of the inner diameter by means of a taper surface, and at the same time, it can make a solid connection between the shaft and the coupling part without the need for keying.
The taper sleeve is a connecting part, which is pressed into the inner surface of the transmission parts such as pulleys through the outer taper surface, and the connecting threaded holes are locked to realize the one-piece type.
- Module: ZJ8
- Material: S45C
Benefits of Timing Belts and Timing Belts Pulley
1. Accurate transmission, no sliding during operation, with constant transmission ratio;
2. Smooth transmission, with buffering and vibration reduction capabilities, and low noise;
3. High transmission efficiency, up to 0.98, with obvious energy-saving effect;
4. Convenient maintenance, no need for lubrication, and low maintenance costs;
5. The speed ratio range is large, usually up to 10, and the linear speed can reach 50m/s, with a large power transmission range of several watts to several hundred kilowatts;
6. Can be used for long-distance transmission, with a center distance of over 10m;
7. No pollution, can work normally in places where pollution is not allowed and the working environment is relatively harsh.
