Embodiment Construction

[0015] In order to fully explain the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0016] explain: figure 1 The direction of the arrow shown in is the circulation flow direction of the hydraulic oil.

[0017] Such as figure 1 As shown, the embodiment of the present invention provides a dynamic and static pressure bearing loading experimental device. The device includes an oil pumping part (1) and an operating part (10) connected to each other. The operating part (10) includes a cylinder body (11), a two-way pressure shoe (12) and a thrust piston (13). Inside the cylinder body (11) There are a pressurized oil chamber (111), a drive oil chamber (112) and an oil return chamber (113). The pressurized oil chamber (111) is respectively connected with the pump oil part (1) and the oil return chamber (113). The oil chamber (113) communicates with...

Abstract

The invention provides a dynamic and static pressure bearing loading experiment apparatus. The loading experiment apparatus comprises an oil pump portion and a working portion communicating with each other, wherein the working portion comprises an oil cylinder body, a bidirectional pressure tile and thrust pistons. A pressurizing oil pocket, a driving oil pocket and a return oil pocket are arranged in the oil cylinder body, wherein the pressurizing oil pocket respectively communicates with the driving oil pocket and the return oil pocket, the return oil pocket communicates with the oil pump portion, and the bidirectional pressure tile is movably arranged between the pressurizing oil pocket and the driving oil pocket. The oil cylinder body is further provided with six thrust pipelines, which communicate with the driving oil pocket. The thrust pistons are arranged on the tail ends of the thrust pipelines. The bidirectional pressure tile extrudes hydraulic oil in the driving oil pocket to extrude the thrust pistons to move and output pressure, and the end portions of the thrust piston are arranged on a runner plate of a dynamic and static pressure bearing to load the dynamic and static pressure bearing. The problem of frequent replacing shafts to change load in a dynamic and static pressure bearing experiment in the prior art can be solved by employing the loading experiment apparatus.

Description

technical field [0001] The design of the present invention relates to the technical field of hydraulic power, in particular to a dynamic and static pressure bearing loading experimental device. Background technique [0002] At present, hydrodynamic and static pressure bearings have high precision, high rigidity, long life, good vibration absorption and shock resistance, and are mainly used in the spindles of precision machining machinery and high-speed, high-precision equipment. During work, it almost bears the pressure load of the entire mechanical rotating moving parts. Therefore, in the design and development stage of dynamic and static pressure bearings, a series of loading experiments need to be done. In the previous dynamic and static pressure bearing loading experiments, various shafts of different masses were used to carry out pressure load experiments on the bearings. Therefore, the shaft needs to be replaced during each experiment, but there will be installation e...
