A Thrust Bearing Device Using Externally Adjustable Guide Pad Type Vertical Mill

Abstract

The invention discloses a thrust bearing device of a vertical mill adopting external adjustment guide tiles, which comprises a connecting shaft sleeve body, a thrust plate and a frame, the thrust plate is fixed on the connecting shaft sleeve body, and the power output shaft is inserted into the connecting shaft sleeve body. The shaft sleeve body is fixed in the connection shaft sleeve body through key connection; the lower part of the connection shaft sleeve body is inserted into the middle through hole of the frame; it can be directly connected with the power output shaft of the permanent magnet motor to realize The rotation is supported by the guide pad and the thrust pad to ensure the normal rotation of the thrust plate. At the same time, the guide pad can be adjusted by the external rotating part, which is convenient for adjustment.

Description

Technical field: [0001] The invention relates to the technical field related to bush bearings, and more specifically relates to a thrust bearing device of a vertical mill adopting an externally adjusted guide pad. Background technique: [0002] Vertical mill has become a kind of grinding machine widely used in modern cement, coal, electric power, chemical industry and other departments. The grinding material has large particle size, simple and compact process flow, compact structure, small footprint, low power consumption, low steel consumption, low noise, low dust, small wear of grinding rollers, long life, and easy operation. [0003] The driving mechanism of the existing vertical mill is generally driven by the motor to run the reducer. The reducer transmits the force to the thrust bearing on the top through a pair of bevel gears and planetary wheels. The grinding disc is installed on the thrust bearing to drive the grinding disc to rotate. Its structure It is complex an...

Problems solved by technology

[0003] The driving mechanism of the existing vertical mill is generally driven by the motor to run the reducer. The reducer transmits the force to the thrust bearing on the top through a pair of bevel gears and planetary wheels. The grinding disc is installed on the thrust bearing to drive the grinding disc to rotate. Its structure Complicated and bulky, at the same time, the existing variable frequency permanent magnet motor can directly drive the thrust bearing (thrust disc) to rotate to realize the rotation of the grinding disc to reduce its volume. However, the existing guiding thrust installed in the permanent magnet motor Generally, the bearing structure is equipped with a thrust bearing bush and a rolling bearing to be used together. However, the service life of the rolling bearing is low, and it requires frequent maintenance, which is very troublesome and the effect is not ideal.
