Abstract
A cylindrical box gear speed increaser comprises a box, a worm, a worm wheel, a transmission angle gear, a worm-gear angle gear shaft, a pinion mandrel and a pinion, wherein the worm is engaged with the worm wheel to form a worm and worm wheel pair, combining with the geometric feature of the engagement of the worm and worm wheel pair, a self-locking angle is designed, the transmission angle gear is engaged with the pinion to form an isodont high angle gear pair, an included angle is formed between the central axis of the worm-gear angle gear shaft and the central axis of the pinion mandrel, the pinion mandrel is supported by a minitype needle bearing, the pinion mandrel is positioned through that the minitype needle bearing is thrust by a minitype, the box has a cylindrical hollow structure, the left side of the box is closed in, and the right side thereof is completely opened.
Description
Technical field
The utility model relates to a kind of speed changer, especially relates to a kind of gear speeder.
Background technique
Gear speeder commonly used is difficult to realize the output shaft shift reciprocately, and the noise height, and efficient is low, can not be applied in the processing of shoemaking industry Mechanical shoes pit track.
Summary of the invention
The purpose of this utility model provides that a kind of noise is low, efficient is high, can realize the output shaft shift reciprocately, be applied to the miniature speed increaser of gear of shoemaking industry Mechanical shoes pit track.
The purpose of this utility model is achieved in that the miniature speed increaser of a kind of cylindrical box gear, comprises casing, worm screw, worm gear, drive bevel gear, worm gear bevel gear shaft, small gear mandrel, small gear; Worm-gears is formed in described worm and wheel engagement, in conjunction with worm-gears engagement geometrical property, and design self-locking angle; Described drive bevel gear and pinion, tooth depth bevel gear pairs such as composition, the medial axis of the medial axis of worm gear bevel gear shaft and small gear mandrel has angle, and the small gear mandrel is located by the miniature planar thrust bearing by miniature needle roller bearing support; Described casing is the cylinder type hollow structure, its left side sealing, and the right side is a full open end.
When rotary worm, worm screw drives worm gear and rotates, drive drive bevel gear by the worm gear bevel gear shaft, drive bevel gear and worm gear rotate with unequal angular velocity, drive bevel gear drives pinion rotation, the rotation driving pinion mandrel of small gear rotates, and miniature needle bearing, miniature thrust bearing, supporting structure have realized that the small gear mandrel reciprocatingly slides along its medial axis.
The utility model with worm-gears with etc. tooth depth bevel gear pair angle drive the reduction speed ratio and the speed increasing ratio composite mechanism of two-in-one, make small gear mandrel high speed rotating as output shaft, running steadily, noise is low, efficient is high, can be applicable to the processing of shoemaking industry Mechanical shoes pit rail track; The needle bearing of the output shaft using miniature that angle drives, supporting plane are used the thrust bearing location, make the end thrust that has solved limit, cutting hole in supporting cutting radial force again, have also realized the shift reciprocately of opening, shutting down simultaneously; In conjunction with worm gear pair engagement geometrical property, design self-locking angle replaces self-locking device, makes mechanism simplifying, miniature simple and direct, safe and reliable, reduces cost; The wherein left side sealing of body cylinder type hollow structure, bi-side, right side full open end, bearing are put respectively on the left and right side, make the mechanism simplifying compactness, and the weight ratio imported product alleviates 30%.
