AI Technical Summary

Technical Problem

Existing horizontal screw centrifuge filter differentials suffer from problems such as low torque, severe wear, complex structure, high noise, and short service life. In particular, the built-in differential has excessive torque, which increases the load on the equipment, and the rear-mounted differential is difficult to remove metal shavings.

Method used

It adopts a built-in planetary gear differential, combined with a universal rotary joint and an oil cooler, to achieve overall thin oil lubrication and continuous cooling, ensuring the circulation of lubricating oil and expelling metal shavings, reducing vibration and noise.

Benefits of technology

It improves the service life of the equipment, reduces operating noise, ensures smooth transmission, reduces equipment wear, and extends the service life of the equipment.

Abstract

The utility model relates to the technical field of horizontal screw centrifugal machines, and discloses a structure of a built-in planetary differential mechanism of a horizontal screw filtering centrifugal machine, which comprises a rotary drum serving as a centrifugal machine rotor and a screw positioned in the rotary drum, and the end part of the rotary drum is connected with a planetary gear differential mechanism through a torque protector. And the internal structure of the planetary gear differential mechanism penetrates through the rotary drum and is connected with the screw. According to the structure of the built-in planetary differential mechanism of the horizontal screw filtering centrifugal machine, the built-in planetary gear differential mechanism is adopted under the condition that the torque is guaranteed, the structure is simple, only one set of transmission is needed, an overall thin oil lubrication mode is conveniently adopted, and lubricating oil enters the differential mechanism from the universal rotating joint and is discharged from oil outlets of the left and right machine shells of the differential mechanism; and the lubricating is thorough, no chippings are left, the whole structure of the equipment is not towed, the transmission is stable, the vibration is small, the service life of the equipment is prolonged, and the noise during operation of the equipment is reduced.
