Embodiment Construction

[0021] The present invention will be further described below in conjunction with accompanying drawing:

[0022] The measurement principle of the present invention is as figure 1 As shown, the transmission error, backlash and friction torque of the RV reducer can be measured.

[0023](a) When measuring the transmission error, first connect the RV reducer (6) to the precision mounting bracket (25) with bolts, and connect the input of the RV reducer (6) by combining the input connection sleeve (5) with the account cover shaft and the precision input spindle (4), connect the output shaft of the RV reducer (6) and the precision output spindle (8) by connecting the output flange (7) and the account cover, and adjust the input assembly, the RV reducer (6) ) and the position between the output assembly, the controller (20) is connected with the industrial computer (21), and is used to control the movement of the magnetic powder brake (13) and the torque motor (1), and at the same tim...

Abstract

The invention relates to a measuring instrument for comprehensive performances of an RV (rot-vector) reducer and belongs to the technical field of precision testing and metering. The measuring instrument comprises two major parts, wherein a mechanical part mainly comprises a precision mounting support of the RV reducer, an input shaft system, an output shaft system, a torque motor, a shaft coupling, a torque sensor, a magnetic powder brake and a brake mounting support; a measuring and controlling part mainly comprises the torque motor, a controller, a driver, an encoder, a subdivision device, a DSI (digital speech interpolation) card, a data acquisition card and an industrial personal computer. The measuring instrument provided by the invention fills in the blank in testing tables for the comprehensive performances of the RV reducers at home and abroad, and has the advantages of reliable performances, good measurement repeability and accurate measured parameters.

Description

technical field [0001] The invention relates to a comprehensive performance measuring device of an RV reducer, which belongs to the fields of precision test and measurement technology, precision instruments and mechanical transmission. Background technique [0002] The RV reducer is a new type of two-stage planetary gear transmission that combines cycloidal pinwheel planetary transmission and involute transmission—involute spur gear transmission and cycloidal pinwheel transmission. The first stage is driven by the sun gear Composed of three planetary gears, the external mesh of the sun gear and the planetary gear transmits the input power in three ways, which plays the role of deceleration and power splitting; the second stage is composed of three crankshafts and crankshafts connected with the planetary gears. Two cycloidal wheels that transmit power on the shaft, a pin wheel composed of pin teeth, and a planetary carrier that supports the crankshaft on both sides. [0003]...
