The utility model discloses an improve rigidity output bearing capacity, small worm gear speed reducer ware compact structure, big, the small -size high efficiency of drive ratio, the worm wheel bearing is conical bearing, and the worm wheel output form can improve gearbox output rigidity and bearing capacity for the friction taper hole greatly, operate steadily, the noise is little, the practicality is strong, safe and reliable, the appearance is small, simple to operate, superior performance.
Description
Technical field
The utility model relates to retarder, is specifically related to a kind of rigidity that improves and exports bearing capacity, worm type of reduction gearing that volume is little.
Background technique
Worm type of reduction gearing is a kind of power-transmitting unit, and it can realize exporting and input direction vertical-transmission; Velocity ratio is large, compact structure; Two-wheeled engagement is cambered surface contact, and bearing capacity is large; Stable drive, noise are little; Worm and gear has self-locking performance, can play safety protection effect.Therefore, worm type of reduction gearing is widely used in machinery industry.
Traditional worm type of reduction gearing adopts cast iron shell or aluminum enclosure mostly, and output worm wheel aperture wheel hub mostly is cast iron and cylindrical hole adds Flat dey joint.The retarder that model is less exist boundary dimension little while transmitted power also little, can not meet that some are restricted to size design, ouput force be had again to the design needs of larger needs simultaneously.Conical bearing is mainly used in bearing radial direction based on thrust load and axial connected load, bearing capacity is large, be applicable to bear heavy load and impact load axle system, therefore conical bearing and 45 Steel Sheels are used for small-sized worm type of reduction gearing manufacture, export worm wheel aperture wheel hub adopt 45 steel to add cone shape hole connects just can the output rigidity of greatly overall raising retarder, output intensity and bearing capacity.
Model utility content
The worm type of reduction gearing that the technical problems to be solved in the utility model is to provide a kind of compact structure, operates steadily, safe and reliable, small-sized efficient, output rigidity and bearing capacity are large.
The technological scheme that the utility model solves the problems of the technologies described above is, a kind of raising rigidity with following structure is provided to export bearing capacity, worm type of reduction gearing that volume is little: to comprise casing 1, the worm screw 2 be connected with motor output end is installed in casing 1, worm screw 2 two ends are respectively connected with a worm bearing 3, input flange assembly 4 is provided with between worm bearing 3 at one end and casing 1, be provided with the worm gear 5 of the transmission that to be meshed with worm screw 2 below worm screw 2, the two ends of worm gear 5 are respectively provided with one and can improve the worm gear conical bearing 6 that rigidity exports bearing capacity.Worm gear 5 output form is that conical bore exports, and worm gear 5 wheel hub is No. 45 steel, and volume is little, and bearing capacity is large, and the rigidity that greatly can improve retarder exports.
Preferably, described input flange assembly 4 comprises the input flange 41 be connected with motor flange, input flange 41 is provided with and the flange o type circle 42 that seal suitable with input flange 41, is also provided with the input flange oil sealing 43 preventing casing 1 inner fluid from leaking outside between worm screw 2 and input flange 41.
Preferably, described input flange 41 is connected on casing 1 by socket head screw 7, is also provided with locking spring washer 8 between socket head screw 7 and casing 1.
Preferably, described casing 1 is made up of clean steel material.Casing 1 adopts No. 45 steel plates to make, and compact, can improve retarder integral rigidity and intensity.
The beneficial effects of the utility model are mainly: (1) raising of the present utility model rigidity exports bearing capacity, worm type of reduction gearing compact structure that volume is little, the large and small type of velocity ratio are efficient; (2) Worm Bearing is conical bearing, and worm-wheel hub is No. 45 steel, and worm gear output form is friction taper hole, greatly can improve retarder and export rigidity and bearing capacity; (3) operate steadily, noise is little; (4) practical, safe and reliable; (5) little, easy for installation, the superior performance of overall volume.
Accompanying drawing explanation
Form of partly the cuing open plan view of the worm type of reduction gearing that Fig. 1 is raising rigidity of the present utility model output bearing capacity, volume is little.
Form of partly the cuing open side view of the worm type of reduction gearing that Fig. 2 is raising rigidity of the present utility model output bearing capacity, volume is little.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
With reference to accompanying drawing 1-2, raising rigidity output bearing capacity of the present utility model, the worm type of reduction gearing that volume is little, it comprises casing 1, the worm screw 2 be connected with motor output end is installed in casing 1, worm screw 2 two ends are respectively connected with a worm bearing 3, be provided with input flange assembly 4 between worm bearing 3 at one end and casing 1, be provided with the worm gear 5 of the transmission that to be meshed with worm screw 2 below worm screw 2, the two ends of worm gear 5 are respectively provided with a worm gear conical bearing 6 that can improve rigidity and export.In this case, Worm Bearing adopts conical bearing, worm gear 5 output form is friction taper hole, worm gear 5 wheel hub is No. 45 steel worm gears, and reducer shell is No. 45 steel, and volume is little, bearing capacity is large, be applicable to bear heavy load and impact load, and be suitable for the equipment that retarder boundary dimension is restricted, this structural design solves the bearing power improving retarder and the contradictory problems increased with retarder boundary dimension.
Preferably, described input flange assembly 4 comprises the input flange 41 be connected with motor flange, input flange 41 is provided with and the flange o type circle 42 that seal suitable with input flange 41, is also provided with the input flange oil sealing 43 preventing casing 1 inner fluid from leaking outside between worm screw 2 and input flange 41.Adopt Flange joint between motor and retarder, convenient disassembly, larger pressure and higher-strength can be born, good seal performance.
Preferably, described input flange 41 is connected on casing 1 by socket head screw 7, is also provided with locking spring washer 8 between socket head screw 7 and casing 1.Employing socket head screw connects, and join strength is large, and solid, safety coefficient is high.
