Abstract

The invention discloses a device for measuring the center distance and the gear backlash of a gear pair. The device comprises to-be-measured gear pair installation equipment and transmission equipment. The to-be-measured gear pair installation equipment comprises base frames, a support frame and braking equipment of a to-be-measured driven gear, wherein the support frame is arranged on the base frames and is capable of horizontally moving on the base frames. The transmission equipment comprises a cam shaft, a driving shaft and a driven shaft. The transmission equipment is arranged in the support frame; the cam shaft and the driving shaft are the same shaft or two shafts which are in rigid connection; the end part of the cam shaft is provided with a cam; the cam is contacted with the fixed base frames; the driving shaft is provided with an imperfect gear; the driven gear is arranged on the driven shaft; and a to-be-measured driving gear is driven by the driven shaft to rotate. The device is automatic measuring equipment and has functions of automatic measurement, automatic reading and automatic graph and data generation. Not only is the measurement accuracy improved but also the measuring speed is greatly increased. Moreover, the measurement of the gear pair with various transmission ratios can be realized.

Description

technical field [0001] The invention belongs to the measurement field of gear pairs, in particular to a device for measuring the center distance and tooth side clearance of gear pairs. Background technique [0002] In order to ensure the normal meshing operation of the gear pair, oil film lubrication is required between the working tooth surfaces, and the influence of factors such as temperature rise and deformation must be considered between the non-working tooth surfaces. Therefore, between the working tooth surfaces and the non-working tooth surfaces of the gear pair There should be sufficient but not too large side clearance for oil storage and compensation for thermal expansion; in addition, it is also necessary to ensure that the center distance of the gear pair meets the design requirements. [0003] There are single-point method, single-mesh method and double-mesh method for measuring the backlash of gear pairs. The single-point method is used to measure the install...
