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

Embodiment Construction

[0025] The present invention will be further described below in conjunction with drawings and embodiments.

[0026] figure 1 It is a schematic diagram of the overall structure of the present invention. The gear fixture 2 is installed on the upper surface of the trapezoidal screw slider 22 of the linear sliding platform 1 , and the linear sliding platform 1 is placed on the marble workbench of the roughness profiler 3 . The gear fixture suitable for the roughness profiler is a gear fixture that can realize linear movement along the Y axis and rotational movement around the Y axis, and the movement direction and value of the fixture are controlled by a computer. Its measurement principle: the computer controls the motion of the two degrees of freedom of the fixture Y-axis and Y-axis rotation according to the parameters of the gear to be measured, adjust the fixture to make the probe produce the required measurement motion relative to the gear to be measured, and move the probe ...

Abstract

The invention discloses a gear fixture suitable for a roughness profiler. The gear mandrel and the gear are connected through an expansion sleeve, the gear mandrel is connected to the cage of the dense bead shaft system through a short taper, and the output shaft of the motor is through a shaft coupling. The sensor is connected with the dense ball shaft system, and the AC servo motor and the circular grating for position measurement form a closed-loop system. The motor can control the gear to rotate around the X axis. The Y-axis direction uses a linear sliding platform to control the Y-axis movement of the gear, so that the profiler can measure the data of the entire tooth surface. The gear to be tested has two degrees of freedom in the direction of the Y axis and the rotation around the X. Combined with the roughness profiler, it can meet the measurement requirements of all gear tooth surfaces. The designed gear fixture can be used with different types of roughness profilers, and can complete the measurement of gear tooth profile deviation, helix deviation, tooth pitch deviation and tooth surface roughness 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...
