Abstract

The invention relates to the technical field of universal machinery, and provides a gear driver capable of adjusting radial runout and axial endplay of a main shaft. The gear driver aims at solving the problem that accuracy of a main shaft in an existing gear driver cannot be guaranteed. The gear driver comprises the main shaft, a box body and a shaft control mechanism, wherein the shaft control mechanism comprises a taper hole cylindrical roller bearing and a cylindrical thrust bearing, an inner ring of the taper hole cylindrical roller bearing is arranged on the main shaft in a sleeving mode, an outer ring of the taper hole cylindrical roller bearing is fixed in a roller bearing installing hole of the box body, a radial clearance between the inner ring and the outer ring is adjustable, ashaft ring of the cylindrical thrust bearing is arranged on the main shaft in a sleeving mode, a seat ring of the cylindrical thrust bearing is fixed in a thrust bearing installing hole of the box body, and an axial clearance between the shaft ring and the seat ring is adjustable. By adjusting and controlling the taper hole cylindrical roller bearing, the gear driver guarantees that the radial runout amount and the axial endplay amount of the main shaft of the gear driver can be adjusted, and then can guarantee that transmission error of the gear driver is small and driving accuracy of the gear driver is high.

Description

technical field [0001] The invention relates to the technical field of general machinery, in particular to a gear transmission. Background technique [0002] In the gear transmission, there are high requirements on the radial runout and axial movement of the main shaft, especially for precision gear transmissions. However, the control of the precision of the main shaft by most bearing configurations depends entirely on the bearing itself The size of the clearance, when the bearing clearance cannot meet the requirements, it cannot be used. Contents of the invention [0003] In order to solve the problem that the precision of the main shaft in the gear transmission cannot be guaranteed, the present invention provides a gear transmission with adjustable radial runout and axial movement of the main shaft. [0004] The gear transmission according to the embodiment of the present invention includes: a main shaft, a box body and a shaft control structure, the main shaft is suita...
