Abstract
The utility model provides a controllable crescent bearing provided with intersected beams, and belongs to the field of engineering machinery. The controllable crescent bearing is applicable to a hydraulic pump of a cement mixer. A controllable connecting structure is designed on the end face of a retainer; a groove with a strengthening rib and a blind hole is used as the controllable connecting structure; a cylindrical pin is mounted in the blind hole; a hole is formed in the cylindrical pin; a seven-needle penetrates through the hole of the cylindrical pin; the bending end of the seven-needle is connected with an inclined disk; and the vertical end of the seven-needle is connected with a split pin of the hydraulic pump. A pocket hole of the retainer is designed to be square; the pocket hole is combined by two parts; lock beams are additionally arranged at the internal diameter part and the external diameter part of the pocket hole to control sag of rollers; the retainer has an intersected beam structure; and the internal diameter part and the external diameter part of the retainer are intersected with each other, and are lapped and matched with a half outer ring. The crescent bearing is applied to the hydraulic pump; due to a small mounting space, a small deflection angle of the inclined disk and the connecting structure designed on the end face of the retainer, the retainer is controllable, a retainer component cannot slide out of a roller path, or the unbalanced stress of the bearing is avoided.
Description
Technical field
The utility model relates to a kind of mutual wrong beam controllable type crescent moon bearing that has, and is applied in the oil hydraulic pump of concrete mixer, and it belongs to engineering machinery field.
Background technique
Concrete mixer partly is made up of automobile chassis, mixing drum, transmission system, water supply installation etc.Because technical bottleneck, four big parts of homemade transit mixer all are imported equipments and parts.The major function of hydraulic system is with power take-off power, is converted into hydraulic pressure energy discharge capacity and pressure, is output as mechanical energy rotating speed and moment of torsion through motor again, provides power for mixing drum rotates.In the pluger type hydraulic pump of concrete mixer, for control hydraulic pump discharge size need for satisfying the swash plate smooth rotation, have been developed a kind of crescent moon bearing that has mutual wrong beam controllable type plastic-steel frame by the deflection of swash plate.
Summary of the invention
In view of the defective that prior art exists, the utility model provides a kind of mutual wrong beam controllable type crescent moon bearing that has, because little installing space and oblique shallow bid deflection angle designed the selenodont bearing and be applied in this oil hydraulic pump; For preventing that the retainer assembly from repeatedly skidding off raceway or causing the shaft strength inequality after the deflection at swash plate, in retainer end face design controllable linkage structure, deflection angle to retainer during swash plate deflection is controlled, and guarantees that the retainer assembly does not skid off raceway or produces the shaft strength uneven phenomenon.
For achieving the above object, the technological scheme that the utility model adopts is a kind of mutual wrong beam controllable type crescent moon bearing that has, by retainer, roller and semi outer rings are formed, in retainer end face design controllable linkage structure, controlled linkage structure is the groove that has stiffening rib and blind hole, straight pin is installed in the blind hole, and straight pin is provided with the hole, and seven sub-pins pass the hole of straight pin, seven sub-pin curved end are connected on the swash plate, and vertically end is connected in the cotter pin of oil hydraulic pump.The pocket hole of described retainer is designed to the square hole form, the pocket hole is combined by two-part, increases lock bridge control roller sag of chain at pocket hole internal diameter and external diameter position, and retainer is mutual wrong beam structure, its inner-diameter portion whose and outer radius portion misplace mutually, and cooperate with the semi outer rings overlap joint.The material of described retainer is plastic-steel.
After adopting such scheme, compared with prior art have following beneficial effect: the selenodont bearing has been applied in the oil hydraulic pump, because little installing space and oblique shallow bid deflection angle, retainer end face design linkage structure, retainer can be controlled, and the retainer assembly can not skid off raceway or produce the shaft strength uneven phenomenon; Cage bar adopts the misplacement structure, is convenient to the mould production of plastic-steel frame and the moulding manufacturing of plastic-steel frame.Special heat treatment mode is eliminated the lasso internal stress, does not produce the distortion that takes place owing to stress relief when guaranteeing to overlap the astragal cutting.

Embodiment
For understanding a kind of structure that has mutual wrong beam controllable type crescent moon bearing in depth, be described as follows in conjunction with Fig. 1 to Fig. 6:
A kind ofly have a mutual wrong beam controllable type crescent moon bearing, by retainer 3, roller 4 and semi outer rings 1 are formed, in retainer 3 end face design controllable linkage structures, controlled linkage structure is the groove that has stiffening rib and blind hole, and straight pin 5 is installed in the blind hole, straight pin 5 is provided with the hole, seven sub-pins pass the hole of straight pin 5, and seven sub-pin curved end are connected on the swash plate, and vertically end is connected in the cotter pin of oil hydraulic pump.The pocket hole of described retainer 3 is designed to the square hole form, the pocket hole is combined by two-part, increases lock bridge 2 control roller sag of chains at pocket hole internal diameter and external diameter position, and retainer 3 is mutual wrong beam structure, its inner-diameter portion whose and outer radius portion misplace mutually, and cooperate with semi outer rings 1 overlap joint.The material of described retainer 3 is plastic-steel.
The utility model has been applied in the concrete mixer oil hydraulic pump, because little installing space and the swing effect of bearing for the accurately output of control flow rate of hydraulic system, are adopted retainer end face design linkage structure, retainer can be controlled, guarantee the accurate control of flow rate of hydraulic system.The cage bar structure of shift is convenient to the mould production of plastic-steel frame and the mass moulding manufacturing of plastic-steel frame mutually.Special heat treatment mode is eliminated the lasso internal stress, does not produce the distortion that takes place owing to stress relief when guaranteeing to overlap the astragal cutting.
