Gear operation are rotating, and the force is also relatively large, so we have to use the copper sleeve to ensure that its use of time and wear resistance, the main we come to understand the use of copper sleeve processing gear.

一、What oil should be added to the gear brass bushing.

　The action of the punch press is linear reciprocating motion.

 In this case, there is no need for too complicated lubrication, ordinary oil can meet the requirements.

 Or check the lubrication instructions of the product.

 Usually, the lubrication instructions will be attached near the oil filler port on the body of the equipment. Please note.

 We must control the amount of oiling, if less will increase its friction, add more will flow to some other places a lot of oil, will cause the equipment is not beautiful.

二、 the difference between gear brass bushings and bearings.

　A simple small plain bearing is usually used where it is not important or where short-term work is required.

 It can be made of copper powder metallurgy or directly made of copper.

 It has the characteristics of simple structure, low working noise and high impact resistance. 

Copper powder metallurgy or internal linoleum does not require frequent lubrication and is low maintenance. 

The disadvantage is that the resistance is large, especially the static friction coefficient and the coefficient of friction is very different, and easy to vibrate can not be used in the precise place.And it is easy to wear.

　We today briefly introduced the use of copper bushings for gear processing, there are many specific, we will not explain one by one.
