Mounting mechanism for swash plate of oblique plunger pump and driving lever

Abstract

The invention relates to a mounting mechanism for the swash plate of an oblique plunger pump. The mounting mechanism comprises a plunger pump body and is characterized in that a crescent outer ring is fixedly mounted on the plunger pump body, a crescent bearing which can move up and down along the inner curve surface of the crescent outer ring is arranged in the crescent outer ring, and the swash plate of the plunger pump is arranged on the crescent bearing. By the mounting mechanism, the inclination angles of the swash plate on the plunger pump can be adjusted conveniently. The driving lever comprises a driving lever body and is characterized in that the upper end of the driving lever body is provided with an upper bulb in rotation fit with the swash plate, the lower end of the driving lever body is provided with a lower bulb in rotation fit with the plunger pump body, and the middle of the driving lever body is provided with a middle bulb in rotation fit with a crescent bearing retainer. By the three bulbs on the driving lever, the upper part, the middle part and the lower part of the driving lever can be in good rotation fit with the swash plate, the retainer and an adjusting block, motion gaps can be reduced, and the mechanism can operate stable.

Description

technical field [0001] The invention relates to a swash plate installation mechanism and a driving rod of a slanted plunger pump. Background technique [0002] A swash plate is installed in the inclined plunger pump, and the pump pressure of the plunger pump is adjusted by adjusting the angle of the swash plate in the main race. In the traditional inclined plunger pump, the adjustment of the angle of the swash plate is inconvenient and unstable. [0003] Finally, the angle adjustment of the swash plate is facilitated by adding a crescent bearing, but because of the lack of restrictions on the crescent bearing cage, when the swash plate tilts upward, the crescent bearing will slide from the upper end of the crescent outer ring to the lower end, when the swash plate needs to be adjusted When tilting downward, the crescent bearing will always be unable to move upward due to gravity, so that the curved surface motion on the crescent outer ring of the swash plate can no longer re...
