Description
Technical field
The present invention relates to a kind of velometer, and in particular to a kind of dustproof and waterproof velometer.
Background technology
Currently, the application of velometer is more and more wider, therefore it is required that velometer can be normal under various use conditions
Work.Existing velometer, under the serious or moist environment of dust pollution, because sealing is not strong, it may occur that enter ash or by
The phenomenon of tide, cause inner body to produce failure, particularly rotary encoder and be affected, test data is inaccurate.
The content of the invention
The present invention provides a kind of dustproof and waterproof velometer, can under various use conditions normal work, particularly in powder
Can also normal work under the seriously polluted or moist environment of dirt.
Technical scheme is as follows：
A kind of dustproof and waterproof velometer, including base, rotary encoder, stator, bolt, rotating shaft, bearing, bearing block,
Shaft coupling, O-ring seal, shield, fixed cover, gland, sealed hair felt collar and screw, the stator, base, fixed cover and axle
Bearing is bolted together by described, and groove is set between the base and fixed cover, and the O-ring seal is arranged on institute
State in groove；The rotary encoder is arranged on the stator, and the shield is bonded on the base by resin glue；
The bearing is arranged in the bearing block, the rotating shaft be arranged on the bearing in, the rotating shaft by the shaft coupling with
The axis connection of the rotary encoder is together；The gland is provided with circular hole, and the circular hole is enclosed in the rotating shaft, the screw
The gland is fixed on the bearing block and compresses the bearing；Dovetail groove is set at the circular hole of the gland, it is described
Sealed hair felt collar is arranged in the dovetail groove, realizes the sealing between the gland and the rotating shaft.
Described dustproof and waterproof velometer, its preferred scheme are to install bullet between the gland and the sealed hair felt collar
Property collar, the elastic collar are made up of spring steel plate, and the elastic collar is provided with gap, and the cross section of the elastic collar is
M shapes.
Beneficial effects of the present invention are：The dustproof and waterproof velometer of the present invention, by setting O between base and fixed cover
Type sealing ring and the setting sealed hair felt collar between gland and rotating shaft, realize the hermetically sealed of whole device, have reached dust-proof
The purpose of waterproof, can under various use conditions normal work, particularly under the serious or moist environment of dust pollution also
Can normal work.By installing elastic collar between gland and sealed hair felt collar, more ensure that between gland and rotating shaft
Sealing.
