[0002] The transmission shaft sleeve assembly includes a transmission shaft and a shaft sleeve, in which the shaft sleeve is an embedded copper sleeve. The shaft sleeve is designed to reduce friction and wear during shaft movement. Its basic use is the same as that of a bearing, but it is relatively cheaper. In the transmission shaft sleeve assembly with a cast embedded copper sleeve, the copper sleeve is placed between the shaft and the supporting structure, and is tightly attached to the supporting structure. Only the shaft can rotate on the copper sleeve. During assembly, lubricant is added between the shaft and the copper sleeve to reduce friction during rotation.
