Ball screws can be lubricated to improve wear resistance and transmission efficiency. Lubricants are divided into two categories: lubricating oil and grease. Lubricating oil is used for motor oil.
Ball screws are the core components of precision instruments and large machine tools used in the automation machinery and equipment industry. They have been widely used for a century since they were created, but their improvement has not stopped. With the continuous increase in the natural complexity coefficient, the corresponding maintenance difficulty coefficient has also increased.
The way to keep the screw dominant in daily life is to use matching grease or lubricating oil to inject, thereby increasing the overall running speed, which is the same as injecting lubricating oil on the chain.
With the development trend of industrial automation, more and more companies use precision transmission equipment, which is also a major problem in maintenance. Especially in lubricating oil and grease, lubricating oil is usually injected into the body of the machine through a hole on the ball screw housing as a vent. Since the main operation of the screw is generated by friction, attention should be paid to the friction and loss mode of the assembly.
It is usually sealed with a felt ring to ensure that no dirt is mixed in, which will hinder the normal operation of the screw and increase the wear of the screw. If it is exposed to the outside for a long time, a certain protective facility should be used with a sleeve to reduce the erosion of rainwater and damage caused by external non-human factors.
