A Combined Bearing with Limited Swivel Angle

Abstract

The invention belongs to the technical field of steering engines and particularly relates to a finite swinging angle combination bearing. The finite swinging angle combination bearing mainly comprisesan output shaft, a front end face holder, front end thrust rollers, a support, a front end roller pin roller, a front end roller block ring, a rocker arm, a roller inner ring, a back end roller pin roller, a back end roller block ring, a back end face holder, back end thrust rollers, a locking end cap, a fastening screw and a countersunk head screw. The problems that an inner ring and an outer ring of an existing bearing of a discrete structural form need to occupy a part of space, and an output shaft and a shell assembly of the output shaft need to be designed to limit axial movement of theroller pin roller bearing, so that the size and the weight are increased are solved. The finite swinging angle combination bearing adopts functional reuse, the output shaft partially achieves the function of a bearing inner ring, the support partially achieves the function of a bearing outer ring, thus the size and the weight are significantly decreased, and the function of the combination bearingis enhanced.

Description

technical field [0001] The invention belongs to the technical field of needle roller bearings, and in particular relates to a limited swing angle combined bearing. Background technique [0002] With the development of science and the advancement of technology, people have put forward more and more stringent requirements on the volume and weight of industrial products. Especially in the field of aircraft technology, in order to increase the payload of the aircraft, technicians are constantly trying to reduce the volume and weight of the aircraft's own equipment. [0003] Especially when supporting the rudder surface of an aircraft, new requirements require that the rudder surface support mechanism should be small in size, light in weight, large in carrying capacity, and have the function of limiting the swing angle. Among the rolling bearings, the needle roller bearing is the bearing with the highest bearing capacity under the same volume and weight. In the prior art, the in...

AI Technical Summary

Problems solved by technology

Among the rolling bearings, the needle roller bearing is the bearing with the highest bearing capacity under the same volume and weight. In the prior art, the inner and outer rings of the ball bearing have a separate structure and need to occupy a part of the space. In addition, due to its structural characteristics, the needle roller bearing needs to be used. Restricting its axial movement requires the design of the output shaft and its housing assembly, resulting in an increase in size and weight
