Large tonnage actuator servo cylinder base

Abstract

The invention discloses a large-tonnage actuator servo-cylinder base which comprises a screw, a load sensor flanged housing, a connecting stand, a shaft, a bearing and a bearing pedestal, wherein the load sensor flanged housing is fixedly connected with the bearing pedestal, the screw is arranged between the load sensor flanged housing and the bearing pedestal, the bearing is matched and connected with the bearing pedestal, the bearing and the connecting stand are fixedly connected by the shaft, and the bearing pedestal is provided with an adjusting screw assembly which can adjust a clearance between the bearing pedestal and the bearing. The large-tonnage actuator servo-cylinder base can eliminate oil-free self-lubricating bearing clearances, and can furthest eliminate a clearance between the bearing pedestal and the bearing when a device works, therefore, the dynamic response performance of a testing machine is improved, and the service life of the testing machine is prolonged.

Description

technical field [0001] The invention relates to the field of hydraulic cylinders, in particular to a servo cylinder base for a large-tonnage actuator. Background technique [0002] Generally, there is a gap between the bearing seat and the bearing shell in the actuator cylinder, and there is also a gap between the bearing shell and the inner shell. However, the actuator cylinder is used in the testing machine industry. In order to avoid the influence of these gaps on the material test during work, it must be Otherwise, the data from the material test will be intermittent and inaccurate. Contents of the invention [0003] The main technical problem to be solved by the invention is to provide a large-tonnage actuator servo cylinder base with compact structure, strong and durable structure, which can eliminate the gap between the bearing seat and the bearing to the greatest extent, thereby improving the dynamic performance of the testing machine. [0004] In order to solve t...
