Problems solved by technology

[0004] In order to solve the problem that the existing aviation bearing tester is single-loaded and the spring buffer and vibration-absorbing device cannot meet the requirements of the aviation bearing test with a wide range of test loads, the invention further proposes an electric cylinder loaded by a combination of one large spring and two small springs. Double spring buffer device

Embodiment Construction

[0010] Such as figure 1 As shown, the electric cylinder is loaded with a double spring buffer device, including a loading cylinder 8, a left end cover 4 and a right end cover 11; the left end cover 4 is detachably connected to the left end of the loading cylinder 8, and the right end cover 11 is connected to the loading cylinder 8 The right end is detachably connected, and the electric cylinder loaded double spring buffer device also includes a large compression spring 1, a first support sleeve 2, a small spring loaded piston rod 6, a small compression spring 7, a second support sleeve 10 and a loading head 12; The first support sleeve 2 can cooperate with the shaft hole at the left end of the inner cavity of the loading cylinder 8 to slide relative to the axial direction, and the second support sleeve 10 can cooperate with the shaft hole at the right end of the inner cavity of the loading cylinder 8 to slide relative to the axial direction. The right end of the second support...

Abstract

The invention discloses an electric cylinder loading dual-spring buffer device and belongs to the field of aircraft bearing test equipment. In order to solve the problems that an existing aircraft bearing tester is simple in loading mode and a spring buffer vibration absorption device cannot meet the aircraft bearing test requirement of test load wide-range change, a second supporting sleeve is provided with a large-diameter hole and a small-diameter hole from left to right, and the large-diameter hole and the small-diameter hole are through and coaxial. A stepped through hole of a first supporting sleeve communicates with the large-diameter hole of the second supporting sleeve. The right end of the first supporting sleeve is inserted into the large-diameter hole of the second supporting sleeve. A small spring loading piston rod is inserted into the stepped through hole of the first supporting sleeve. A small compression spring is arranged in the stepped through hole of the first supporting sleeve and is further arranged on the small spring loading piston rod in a sleeving mode. A large compression spring is arranged on the cylindrical surface at the outer side of the first supporting sleeve and the cylindrical surface at the outer side of the second supporting sleeve in a sleeving mode. By adoption of the electric cylinder loading dual-spring buffer device, the consistency ofactual bearing loads of a rolling bearing and the loads specified in a test load spectrum within the whole test load variation range is improved, and the confidence level of aircraft bearing test results with test load wide-range change is guaranteed.

Description

technical field [0001] The invention belongs to the field of aviation bearing test equipment, in particular to an electric cylinder loading device. Background technique [0002] When a military aircraft performs a mission, the aero-engine generally goes through several stages such as ground idle, take-off, climb, cruise, supersonic flight, descent, refueling, rush, ground idle, etc. The load borne by the main shaft bearing of the aero-engine is Due to the characteristics of large-scale changes in the aircraft bearing test, the test load spectrum is required to simulate the load conditions of the aircraft bearing as much as possible, that is, the process of simulating the large-scale change of the aircraft bearing load. [0003] The electric cylinder loading device is an electric drive loading device that converts the rotation of the screw driven by the motor into the linear motion of the nut, thereby realizing the reciprocating motion of the output shaft. It has been used to...
