Gear clamp suitable for roughness profilometer

Abstract

The invention discloses a gear clamp suitable for a roughness profilometer. A gear spindle is connected with a gear through an expanding sleeve, the gear spindle is connected to a retainer of a bead shafting through a short cone, a motor output shaft is connected with the bead shafting through a coupler, a closed-loop system is formed by an AC servo motor and a circular grating for position measurement, and a gear can be controlled by a motor to rotate around the X axis. A linear slip platform can be used in the direction of the Y axis to control the gear to move around the Y axis, so that data of the entire gear surface can be measured by the profilometer. A measured gear is provided with freedom in both directions of the Y and X axes. Combined with the roughness profilometer, all measurement requirements of the gear surface can be met. The designed gear clamp can be matched with different types of the roughness profilometers, and measurement for gear profile deviation, helical deviation, gear pitch deviation and roughness of the gear surface can be completed under the same clamping condition.

Description

technical field [0001] The invention relates to the technical field of gear measurement, in particular to a gear fixture suitable for measuring gears with a roughness profiler. Background technique [0002] At present, the commonly used gear measurement methods include gear measurement center, three-coordinate measuring machine, portable gear measuring machine and measuring equipment based on optical measurement technology. Existing gear measurement equipment can measure gear tooth profile deviation, tooth pitch deviation, radial runout and other items, but cannot simultaneously measure gear tooth surface roughness. In order to ensure that the transmission gear reduces the influence of unfavorable factors such as gear transmission noise, shock, and vibration under the rated power, to ensure that the gear transmission has high working stability, and to make the instantaneous speed ratio change of the gear transmission as small as possible, the gear must be adjusted. The manu...

Problems solved by technology

[0003] At present, there is no special fixture suitable for the roughness profiler. The existing clamping method is to fix the gear directly on the marble workbench of the roughness profiler through the clamping device. Each fixation can only achieve a single tooth profile of the gear. Measurements are made and clamping is difficult

The clamping conditions are different each time, the measurement repeatability is relatively low, and the measurement results cannot evaluate all tooth profiles of the gear at the same time
