Internal circular cooling ball screw device

Abstract

The invention discloses an internal circular cooling ball screw device. The internal circular cooling ball screw device comprises an upper limiting block and a lower limiting block; a lead screw is arranged between the upper limiting block and the lower limiting block, a nut base is arranged on the lead screw, the nut base comprises a large cylinder body and a small cylinder body, the large cylinder body is connected to the small cylinder body in a sleeving manner, a frame hole is formed in the large cylinder body, a framework cross beam is arranged in the frame hole, the two ends of the framework cross beam are fixedly connected with the frame hole, an exhaust pipe hole is formed in one end of the framework cross beam, a cooling air pipe is arranged in the exhaust pipe hole in a penetrating manner, the two ends of the cooling air pipe are connected with an outer air pipe, a micro fan is arranged in one end of the outer air pipe, and a pressurized fan is arranged in the other end of the outer air pipe. The structure is steady, the air cooling method is adopted, the circular cooling function is added in the ball screw device, generated heat is effectively reduced, the structural strength is high, the cooling device is small in size, the scheme is reasonable, the dustproof air circular cooling method is adopted, and the use efficiency of the ball screw device is not affected.

Description

technical field [0001] The invention relates to the technical field of ball screw machines, in particular to a ball screw device with internal circulation cooling. Background technique [0002] Ball screw is an ideal product for converting rotary motion into linear motion, or converting linear motion into rotary motion. Ball screw is the most commonly used transmission element in tool machinery and precision machinery. Its main function is to convert rotary motion into linear motion, or convert torque into axial repetitive force, while combining the characteristics of high precision, reversibility and high efficiency. Due to its small frictional resistance, ball screws are widely used in various industrial equipment and precision instruments. Ball screws are composed of screws, nuts, steel balls, preloaders, reversers, and dust collectors. Its function is to convert rotary motion into linear motion, which is the further extension and development of Acme screw. The significa...

Problems solved by technology

[0003] However, due to the continuous upward and downward operations of the ball screw during use, the friction between the ball and the thread generates heat, which accelerates the friction loss of the ball, seriously affects the performance of the ball screw device, and reduces the service life. , and there is no new type of cooling device added to the ball screw device
