Abstract
The utility model relates to a kind of velometer, is specifically related to a kind of dustproof and waterproof velometer.The technical solution of the utility model is: a kind of dustproof and waterproof velometer, comprise base, rotary encoder, stator, bolt, rotating shaft, bearing, bearing seat, shaft coupling, O RunddichtringO, guard shield, fixed cover, gland, sealed hair felt collar and screw, together with stator, base, fixed cover are bolted with bearing seat, arrange groove between base and fixed cover, O RunddichtringO is arranged in groove; Gland is provided with circular hole, and circle hole sleeve is in rotating shaft, and gland to be fixed on bearing seat and to be compressed by bearing by screw; The circular hole place of gland arranges dovetail groove, and sealed hair felt collar is arranged in dovetail groove, realizes the sealing between gland and rotating shaft.Velometer of the present utility model, normally can work, particularly can also normally work under the environment that dust pollution is serious or moist under various service condition.
Description
Technical field
The utility model relates to a kind of velometer, is specifically related to a kind of dustproof and waterproof velometer.
Background technology
Current, the range of application of velometer is more and more wider, therefore requires that velometer normally can work under various service condition.Existing velometer, under the environment that dust pollution is serious or moist, because sealing is not strong, the phenomenon can entered ash or make moist, cause inner body to produce fault, particularly rotary encoder is affected, and test data is inaccurate.
Utility model content
The utility model provides a kind of dustproof and waterproof velometer, normally can work, particularly can also normally work under the environment that dust pollution is serious or moist under various service condition.
The technical solution of the utility model is as follows:
A kind of dustproof and waterproof velometer, comprise base, rotary encoder, stator, bolt, rotating shaft, bearing, bearing seat, shaft coupling, O RunddichtringO, guard shield, fixed cover, gland, sealed hair felt collar and screw, be bolted together described in described stator, base, fixed cover and bearing seat pass through, arrange groove between described base and fixed cover, described O RunddichtringO is arranged in described groove; Described rotary encoder is arranged on described stator, and described guard shield is bonded on described base by resin glue; Described bearing is arranged in described bearing seat, and described rotating shaft is arranged in described bearing, and described rotating shaft is linked together by the axle of described shaft coupling and described rotary encoder; Described gland is provided with circular hole, and described circle hole sleeve is in described rotating shaft, and described gland to be fixed on described bearing seat and to be compressed by described bearing by described screw; The circular hole place of described gland arranges dovetail groove, and described sealed hair felt collar is arranged in described dovetail groove, realizes the sealing between described gland and described rotating shaft.
Described dustproof and waterproof velometer, its preferred version is, installs elasticity collar between described gland and described sealed hair felt collar, and described elasticity collar is made up of spring steel plate, and described elasticity collar is provided with gap, and the xsect of described elasticity collar is M shape.
The beneficial effects of the utility model are: dustproof and waterproof velometer of the present utility model, by arranging O RunddichtringO and arrange sealed hair felt collar between base and fixed cover between gland and rotating shaft, achieve the hermetically sealed of whole device, reach the object of dustproof and waterproof, normally can work under various service condition, particularly can also normally work under the environment that dust pollution is serious or moist.By installing elasticity collar between gland and sealed hair felt collar, more ensure that the sealing between gland and rotating shaft.
