Problems solved by technology

However, this method has high requirements on the accuracy of the grating. The scale of the grating disc used in the test must meet the test accuracy requirements, and the purchase of high-precision grating discs usually needs to be imported from abroad, which will lead to high test costs and long procurement cycles.

Embodiment Construction

[0036] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0037] Such as figure 1 The schematic diagram of the structure of the test bench is shown, including the loading assembly, the rotation lock assembly, the test bench support assembly, the driving axle assembly, and the driven axle assembly.

[0038] The loading assembly is composed of loading arm 9, arm brake disc 8, weight 1, arm hook 2, hook stopper 3, and locking bolts (bolts used to lock the loading arm and arm brake disc) .

[0039] The force arm brake disc 8 and the load force arm 9 are installed on the right end of the drive shaft 15, and the shaft shoulder and the drive shaft shaft end cover 19 are fixed by the drive shaft 15; the force arm hook 2 is hung on the load force arm 9 horizo...

Abstract

The invention discloses a cylindrical gear pair quasi-static transmission error test bench, a test method and a data processing method. The cylindrical gear pair quasi-static transmission error test bench is characterized by comprising a loading component, a rotation locking component, a test bench support component, a driving axle component and a driven axle component. The driving axle componentand the driven axle component which are connected to each other are successively disposed on the test bench support component. The loading component is mounted on a driving shaft end in the driving axle component. The rotation locking component is mounted on a driven shaft end in the driven axle component. The cylindrical gear pair quasi-static transmission error test bench has beneficial effectsthat 1) the test bench has only one cylindrical gear pair and a support mechanism for the meshing transmission of the cylindrical gear pair, and is compact in structure, small in occupied space, and convenient to maintain; 2) the test bench is loaded by a weight and does not require driving equipment such as a motor, a magnetic powder brake and the like so as to save funds and shorten an equipmentprocurement cycle; 3) test measurement can be performed just by normally meshing and loading a gear equipped with a strain gage.

Description

technical field [0001] The invention relates to a quasi-static transmission error test bed of a cylindrical gear pair, a test and a data processing method, and belongs to the technical field of transmission error testing of a cylindrical gear pair. Background technique [0002] Gear transmission is the most commonly used mechanical form in mechanical transmission. It has the advantages of reliable operation, high efficiency, compact structure and long life, so it is widely used in various mechanical equipment. [0003] Transmission error is used to measure the accuracy of gear transmission. It is an important parameter that affects the working accuracy, vibration, noise, reliability and life of gears. [0004] During the meshing transmission process of the gear, with the expansion of the tooth surface wear, the tooth profile error, base joint error and tooth side clearance of the gear will also increase; in addition, there are inevitably manufacturing and installation errors...
