Description
Technical field
The utility model relates to a kind of retarder.Be widely used in every field such as truck-mounted crane, high-altitude operation vehicle, solar tracker.
Background technique
Traditional retarder has gear reducer and worm type of reduction gearing etc. at present.Worm type of reduction gearing is to be converted into mechanical energy by dynamical element discharge pressure energy or electric energy to executive component, drive worm screw and transmit certain torque drive worm gear rotation, it is that worm gear and output shaft rotate synchronously that the worm gear output shaft relies on key to be connected with worm gear, the worm gear output shaft need outreach connecting plate in addition, realizes slowing down thereby finish 0-360 ° of rotation motion.It mainly has the following disadvantages:
1, on the performance: the conventional worm worm speed reducer is coupling shaft output, and coupling shaft need adopt corresponding bearing to position, and rotates.Bearing can bear certain axial force, radial force, but does not possess the ability of the tilting moment that bears certain load.Can not use under operating mode comparison rugged environment, applied range is narrower.
2, on the structure: conventional worm worm speed reducer basic structure adopts worm and gear to carry out transmission, and structure is cumbersome and take bigger space, and space availability ratio is low, the dismounting inconvenience.
3, on the efficient: the conventional worm worm speed reducer needs to be made of executive component → worm screw → worm gear → output shaft → connecting plate etc.Because its process complicated machinery efficient is lower.
4, on the life-span: do not possess the ability of the tilting moment that bears certain load, working life is shorter.
5, under the situation of same extraneous load, the physical dimension of traditional worm type of reduction gearing is big, and corresponding manufacture cost also increases thereupon.
6, the worm gear periphery is not provided with fence, and the external tooth on the worm gear easily bumps damaged bad.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and can bear certain axial force and radial force, and the tilting moment and the worm gear that can bear certain load again are difficult for bumping damaged bad enclosure type rotary decelerator.
The purpose of this utility model is achieved in that a kind of enclosure type rotary decelerator, comprises worm screw, pedestal pivoting support and fence,
Described pedestal includes axle housing and seat ring, and axle housing and seat ring fuse, and the shaft axis of axle housing and the shaft axis of seat ring are orthogonal in the spatial position,
Described endless screw apparatus in the axle housing of pedestal,
Described pivoting support include inner ring, external toothing and be embedded at inner ring and external toothing between steel ball or roller, inner ring is fixedly connected on an end of the seat ring of pedestal, external toothing and worm meshing,
Described fence is located on the pedestal of pivoting support periphery.
This retarder is converted into mechanical energy by certain oil liquid pressure energy or the electric energy that executive component oil hydraulic motor or electric motor acquisition exterior power element provide, and carries out clockwise or counterclockwise 0-360 ° of rotation rotation motion thereby drive ring surface enveloped type worm screw transfer larger torque driving rotational supporting.Worm screw, pivoting support, executive component rely on pedestal to fix, and form integral structure.This retarder can satisfy client for moment of torsion, speed and distance between center line from 3 " (76mm) to 28 " (711mm) needs of different requirements.
The utility model retarder adopts the ring surface enveloped type worm screw and the pivoting support of band external tooth to carry out transmitting torque, be the two-wire contact during this worm gear pair flank engagement, the normal velocity of point of contact is big, composite curve radius is big, contact stress is little, easily forms oil film, and it is big to have bearing capacity, the efficient height, advantages such as long service life.Concrete advantage is as follows:
1, on the performance: this retarder has adopted pivoting support to carry out rotation motion, pivoting support adopts single contact ball slewing bearing, and compact structure is in light weight, steel ball or roller contact with the raceway of seat ring, can bear axial force, radial force, tilting moment simultaneously.So this retarder can use applied range under the operating mode rugged environment.
2, on the structure: this retarder adopts first that worm screw cooperates with pivoting support, transmission, and relies on pedestal that pivoting support, worm screw, executive component are carried out relative positioning, forms integral structure.Comparatively speaking, this retarder has advantages such as simple in structure, compact appearance, space availability ratio height, easy accessibility.
3, on the efficient: this retarder is made of executive component → worm screw → pivoting support → connecting plate.Because the simple and mechanical efficient of its process is than higher.As adopt the oil hydraulic motor of same model, under the situation of volumetric efficiency unanimity, the total efficiency of this retarder is than traditional worm gear reducer height.
4, on the life-span: because the difference on the performance, under the situation of same operating mode, the working life of this retarder is than traditional length.
5, on the cost: because structural difference, under the situation of same extraneous load, the physical dimension of this retarder is littler than this swivel gear, and corresponding manufacture cost also reduces thereupon.
6, the pivoting support periphery is provided with fence, and the external tooth on it can not bump damaged bad.
