Embodiment Construction

[0020] In order to make the present invention more comprehensible, preferred embodiments are described in detail below with accompanying drawings.

[0021] The present invention is a hydraulic motor inertia loading test device, such as figure 1 with figure 2 As shown, the platform 2 is a square, and a pillar 1 is welded at its four corners. There are three sets of bolt holes on the platform 2, which are respectively used to install the slewing support 3 and the tested hydraulic motor reducer assembly 6. and load module 5. The four pillars 1 are respectively arranged on the four corners of the platform 2, and the four pillars 1 are of the same height, and are placed on the ground to support the platform 2; the slewing support 3 is connected under the platform 2 through the second bolt B2, and the slewing support 3 includes the connection Disc 304, ring gear 302, steel ball 303 and chassis 301 four parts, such as image 3 shown. Wherein, the connection plate 304 is connecte...

Abstract

The invention discloses a hydraulic motor inertia loading test device which is characterized in that the device comprises a platform, support columns placed on the ground to support the platform are welded to the bottom of the platform, a rotary support is connected under the platform, a tested hydraulic motor reducer assembly and a reducer are arranged on the platform, and the reducer is connected with a loading module. The characteristic of the reducer is used reversely, namely, the speed of a tested hydraulic motor is reduced and the torque is increased by the reducer, then, the speed is increased and the torque is reduced reversely by the reducer, and finally, the actions are transferred to the loading module, so the mass and size of the loading module are reduced, and layout and processing are facilitated. Meanwhile, the mass of the loading module is adjustable, namely, the corresponding load is adjustable, which facilitates design and adjustment of acceleration test.

Description

technical field [0001] The invention relates to a hydraulic motor inertial loading test device, which belongs to the technical field of hydraulic motor acceleration tests. Background technique [0002] Plunger hydraulic motors are widely used in various construction machinery and construction machinery due to their advantages of compact structure, high energy density, small size and easy layout. Driven by hydraulic motor reducer assembly. Among them, when the excavator is working, digging → turning → unloading → turning (reverse direction) → digging constitutes a working cycle. During each turning operation, due to the inertia of the excavator, at the moment of starting and stopping, there will be forward and reverse rotation. The impact loads in two directions cause the hydraulic motor reducer assembly used to drive the excavator to rotate. In one working cycle, it has withstood 4 impact loads in both positive and negative directions. The working conditions are very bad. I...
