Problems solved by technology

[0002] In the past, when it was necessary to install the left and right bearing rings of the wheel hub and the left and right bearings of the wheel hub on the installation positions of the left and right bearing rings of the left and right shaft tubes of the rear axle hub in engineering vehicles, it was often necessary to use the beetle to fix the left and right bearing seats of the wheel hub. The ring and the left and right bearings of the wheel hub are knocked in place, which not only easily damages the left and right bearing rings of the wheel hub and the left and right bearings of the wheel hub, but also has high labor intensity and low work efficiency. Therefore, it is necessary to design a special press-fit assembly for engineering vehicle wheel bearings and seat rings , press the hub left bearing race and the hub left bearing to the installation position of the hub left bearing race and the hub left bearing respectively through the oil pressure of the hydraulic machine, and at the same time respectively press the hub right bearing race through the oil pressure of the hydraulic machine Press fit the right bearing of the hub to the mounting position of the right bearing ring of the hub and the mounting position of the right bearing of the hub

Abstract

The invention discloses a hub bearing for engineering trucks and a special press-fitting assembly for races and relates to the field of special press-fitting assemblies for mounting hub bearings and hub bearing races on rear-axle hub shaft tubes. A left cylinder work oil nozzle (16) and a left cylinder block return oil nozzle (24) are respectively arranged on a left cylinder (1) and a left cylinder block (5) which are connected with each other, and a right cylinder work oil nozzle (17) and a right cylinder block return oil nozzle (25) are respectively arranged on a right cylinder (2) and a right cylinder block (6) which are connected with each other; a front support rod (9) and a rear support rod (10) are connected between a left support rod holder (7) provided with the left cylinder block (5) and a right support rod holder (8) provided with the right cylinder block (6); a left cylinder piston (3), a left thrust connecting rod (32) and a left pressure tool (11) are integrally connected, and a right cylinder piston (4), a right thrust connecting rod (33) and a right pressure tool (12) are integrally connected. The special press-fitting assembly for the races is simple in structure and high in press-fitting speed.

Description

technical field [0001] The invention discloses a special press-fitting assembly for wheel hub bearings and seat rings for engineering vehicles, which involves press-fitting the wheel hub bearings and the wheel hub bearing seat rings into the wheel hub bearing installation position and the wheel hub bearing seat ring of the rear axle hub shaft tube of the engineering vehicle through the press-fitting components. field of dedicated press-fit components on the bit. Background technique [0002] In the past, when it was necessary to install the left and right bearing rings of the wheel hub and the left and right bearings of the wheel hub on the installation positions of the left and right bearing rings of the left and right shaft tubes of the rear axle hub in engineering vehicles, it was often necessary to use the beetle to fix the left and right bearing seats of the wheel hub. The ring and the left and right bearings of the wheel hub are knocked in place, which not only easily ...
