Abstract
The invention discloses a belt pulley mechanism and particularly relates to a belt pulley fastening mechanism. The belt pulley fastening mechanism comprises a belt pulley body and a dustproof cover. Embedding grooves are formed in the outer circumferential face of the belt pulley body. The belt pulley body is sleeved with an outer ring. Protruding keys inserted in the embedding grooves are arranged on the inner wall of the outer ring. A protrusion is arranged on one side of the outer ring. An installation sleeve for fixing operation is arranged between the dustproof cover and the protrusion and comprises a hollow sleeve and a flat cushion board fixedly arranged at one end of the hollow sleeve. Spring steel sheets evenly distributed on the hollow sleeve circumferentially are arranged at the other end of the hollow sleeve. The length direction of the spring steel sheets is perpendicular to the axis direction of the hollow sleeve. Installation holes which the hollow sleeve penetrates are formed in the dustproof cover and the protrusion. The dustproof cover and the protrusion are clamped between the flat cushion board and the spring steel sheets. By the adoption of the belt pulley fastening mechanism, the technical defect that bolts of only one specification can be used for fixing operation in the prior art is overcome, and the belt pulley fastening mechanism is small in installation limit.
Description
Technical field
The present invention relates to a kind of pulley mechanism, be specifically related to a kind of belt pulley retention mechanism.
Background technique
Belt pulley, belong to hub class part, general relative size is larger, generally to cast, to be forged to master in manufacturing process.What stock size was larger is designed to the method using casting, and material is generally all cast iron, seldom uses cast steel; Stock size is less, can be designed as forging, and material is steel.Belt pulley is mainly used in the occasion of Long Distant Transmit power, the output of such as miniature diesel mechanomotive force, agricultural vehicle, tractor, automobile, mining machinery, machining equipment, textile manufacturing machine, package packing machine, lathe, forging bed, the transmission of some fraction horsepower motorcycle powers, the transmission, air compressor, retarder, speed reducer, generator, Gins etc. of farm machinery power.
In pulley drive process, easily suck a large amount of dust in side.
In order to solve the problems of the technologies described above, Chinese patent CN105042036A discloses a kind of compressor pulley used for automobile air conditioning, this compressor pulley used for automobile air conditioning comprises pulley body, caulking groove, outer shroud, convex body, dust cover, described pulley body is provided with caulking groove, and pulley body is fixedly connected with by caulking groove with outer shroud; The fluted structure of described outer shroud arranged outside; Described outer shroud inside edge is provided with the protruding structure corresponding with the caulking groove in pulley body; The top, side of described belt pulley is provided with convex body, and is equipped with the dust cover corresponding with belt pulley; Convex body in described dust cover and belt pulley is bolted.
But still there is following technological deficiency in above-mentioned prior art:
Be bolted, need to process corresponding screw thread respectively on dust cover and convex body, and once screw thread process completes, described dust cover and belt pulley just can only be fixed by a kind of bolt of specification, install and are restricted.
Summary of the invention
The invention is intended to provide a kind of belt pulley retention mechanism installing less-restrictive.
Belt pulley retention mechanism in this programme, comprises pulley body and dust cover, and the outer circumferential face of pulley body is provided with caulking groove, is arranged with outer shroud outside described pulley body, and the inwall of described outer shroud is provided with the convex key with described caulking groove grafting; The side of described outer shroud is provided with convex body, fixing installation sleeve is provided with between described dust cover and described convex body, described installation sleeve comprises a hollow sleeve and is fixedly arranged on the flat bolster of hollow sleeve one end, the other end of described hollow sleeve is provided with circumference and is distributed on spring steel plate in hollow sleeve, the length direction of spring steel plate and the axial direction of described hollow sleeve perpendicular, described dust cover and convex body are provided with the mounting hole penetrated for described hollow sleeve, and described dust cover and convex body are clamped between described flat bolster and spring steel plate.
Adopt technological scheme of the present invention, there is following technique effect:
Described dust cover and convex body are clamped between flat bolster and spring steel plate, just can not loosen between such dust cover and convex body.Bolt is replaced by the installation sleeve with flat bolster and spring steel plate, so just offer screw thread without on dust cover and convex body, only need to arrange on dust cover and convex body for described installation sleeve by mounting hole, and the size of mounting hole is also not necessarily consistent with the diameter of installation sleeve, only need the diameter being a bit larger tham installation sleeve.
Therefore the design adopting installation sleeve to fix is than the fixing design adopting bolt, and the required precision of its dimensioned is lower, allows to adopt the installation sleeve of different size (as long as diameter is less than mounting hole) to be fixed connection, and be convenient to install.
Further, described hollow sleeve is provided with internal thread, is connected with bolt in described hollow sleeve.
Improvement herein, can be compatible with bolt, namely after reinforcing with installation sleeve, can also increase bolt and reinforce the connection further.
Further, described flat bolster is provided with projection, and described projection is positioned at flat bolster towards on the side of described convex body.
The side of flat bolster towards described convex body arranges projection, and no matter described flat bolster is used for contacting with convex body or contacting with dust cover, and described projection can prevent flat bolster from sliding relative to convex body or dust cover.
Further, described flat bolster is regular hexagon.
Described flat bolster is arranged to regular hexagon, is conducive to being hold by one hand operation.
