Abstract

The invention relates to an atress testing device for cycloid pin tooth meshing. According to the device, a cycloid pin gear mechanism is arranged on an experimental table bracket by threaded conenction, the arrangement position corresponds to an angle and position of a force sensor, and the cycloid pin gear mechanism is fixedly connected with a lever through a fixed pin to be combined into a force testing input end; a force transmitting pin roll is fixedly connected with the inner side pin tooth of the cycloid pin gear mechanism, the force transmitting pin roll is connected with mechanical sensors, and the mechanical sensors are fixed to the experimental table bracket through a screw rod to form a force testing end. According to the atress testing device, a force transmitting adjusting test is carried out on a plurality of mechanical sensors at a certain precise angle, and the quantity and test precision of test data are increased; a pin tooth shell is integrally separated with the experimental table bracket, the force transmitting pin roll with different sizes is matched to achieve the force test referring to the cycloid pin gear with different modulus and tooth numbers, the flexibility of the force test of the device is improved, and the applicable range is expanded; a lever-type light weight structure greatly reduces the device size, the material cost is reduced, and transport and assembly are convenient.

Description

technical field [0001] The invention relates to the technical field of cycloidal pin wheel testing, and relates to measuring the force of cycloidal pin gears in a cycloidal pin wheel reducer during the meshing process, and in particular to a force test for the meshing of cycloidal pin gears in a precision reducer device. Background technique [0002] The transmission characteristics of the precision reducer are as follows: [0003] (1) High transmission ratio, high transmission precision and small hysteresis [0004] (2) Large torsional rigidity and strong bearing capacity [0005] (3) Stable transmission and low noise [0006] (4) High transmission efficiency [0007] Due to the above characteristics, precision reducers are mostly used in environments with stricter requirements such as robots, and its performance needs to meet higher requirements, so the testing of its various performance indicators is also particularly important. Therefore, the precision reducer test ...
