Description
Technical field
The utility model relates to the automobile gearbox field, is specifically related to a kind of gear-box axle speed probe stationary installation.
Background technology
When car transmissions carry out vibration and noise test, need carry out the twisting vibration test to kinematic train, this just need test the rotating speed of gear-box axle.Since gearbox gear with the mounting means of axle inconsistent and the difference to some extent of the spacing between the gear of surveying and the gear box casing, employed photo-electric of while or magnetoelectric sensor are had relatively high expectations to spacing.Therefore, when the gear-box axle rotating speed was tested, the mounting means of speed probe just became the successful key of test.At present, the test of being carried out all is directly speed probe to be sticked on the gear box casing, and this makes that the spacing adjustment between sensor and the gear is very loaded down with trivial details, sometimes even can damage sensor.
Summary of the invention
The purpose of this utility model provides a kind of gear-box axle speed probe stationary installation, can regulate the spacing between sensor and the gearbox gear easily, can avoid the damage of sensor simultaneously.
For achieving the above object, the utility model by the following technical solutions, this device comprises sensor holder, the front end edge axis direction of sensor holder is provided with threaded hole, the thread segment shaft of threaded hole and sensor constitutes threaded engagement, by the tubular cavity that the threaded hole of sensor holder to the rear end face of sensor holder is provided with, inside and outside through hole that tubular cavity is offered by the sensor pedestal or breach were communicated with, sensor holder back segment sidewall was located in the mounting hole of offering on the gear box casing.
By above technical scheme, sensor is directly installed in the threaded hole of sensor holder, and sensor holder is installed on the gear box casing, can conveniently regulate the distance between sensor and gearbox gear, guarantees that simultaneously in test process, sensor does not produce loosening.

Embodiment
A kind of gear-box axle speed probe stationary installation, this device comprises sensor holder 10, the front end edge axis direction of sensor holder 10 is provided with threaded hole 11, threaded hole 11 constitutes threaded engagement with the thread segment shaft of sensor, the tubular cavity 12 that is provided with by the threaded hole 11 of sensor holder 10 to the rear end face of sensor holder 10, inside and outside through hole that tubular cavity 12 is offered by sensor pedestal 10 or breach are communicated with, with the layout that makes things convenient for sensor wire with draw, sensor holder 10 back segment sidewalls are located in the mounting hole of offering on the gear box casing.This device is installed on the gear box casing, and sensor holder 10 stretches into gear box casing inside, adjusts the extension elongation of sensor, just can regulate the distance between sensor and the gearbox gear easily.
Sensor installation seat for convenience, sensor holder 10 comprises sensor front stall 13 and sensor back seat 14, adopts between sensor front stall 13 and the sensor back seat 14 to be threaded, the threaded hole 11 of sensor holder 10 front ends is positioned at sensor front stall 13.
Further, described sensor holder 10 is provided with the flute profile aperture along axis direction by the place, back aperture of the rear end face of sensor back seat 14 threaded hole 11 to the sensor front stall 13, flute profile aperture and the tubular cavity 12 formation open slot 15 that connects.So just sensor installation that can be convenient be convenient to simultaneously sensor with data line layout and draw.
Further, in order to prevent in the threaded hole of sensor holder 10 on gear box casing owing to vibrate cause loosening, adopt set nut locked between the threaded hole that is provided with on the outer wall of sensor back seat 14 and the gear box casing, also adopt set nut locked between the threaded hole 11 of same sensor holder 10 front ends and the thread segment shaft of sensor.So not only guarantee the stability of this device, also improved the accuracy of the measurement of rotating speed data of the gear-box axle that this device gathers.
