Abstract
With mutual wrong beam controllable type crescent moon bearing, be applied in the oil hydraulic pump of concrete mixer, it belongs to engineering machinery field.Design controlled linkage structure at retainer end face, controlled linkage structure is the groove with stiffening rib and blind hole, is installed to by straight pin in blind hole, straight pin is provided with hole, seven sub-pins are through the hole of straight pin, and seven sub-pin curved end are connected on swash plate, and vertically end is connected in the cotter pin of oil hydraulic pump.The pocket hole of described retainer is designed to square hole form, pocket hole is combined by two-part, and increase lock bridge at pocket hole internal diameter and external diameter position and control roller sag of chain, retainer is mutual wrong beam structure, its inner-diameter portion whose and outer radius portion misplace mutually, and overlap with semi outer rings and coordinate.Selenodont bearing has been applied in oil hydraulic pump, and due to little installing space and oblique shallow bid deflection angle, retainer end face design linkage structure, makes retainer control, and retainer assembly can not skid off raceway or produce shaft strength uneven phenomenon.
Description
Technical field
The present invention relates to mutual wrong beam controllable type crescent moon bearing, be applied in the oil hydraulic pump of concrete mixer, it belongs to engineering machinery field.
Background technique
Concrete mixer is made up of parts such as automobile chassis, mixing drum, transmission system, water supply installations.Due to technical bottleneck, four large parts of domestic transit mixer are all imported equipments and parts.The major function of hydraulic system is by power take-off power, is converted into hydraulic energy (discharge capacity and pressure), then exports as mechanical energy (rotating speed and moment of torsion) through motor, provides power for mixing drum rotates.In the pluger type hydraulic pump of concrete mixer, for hydraulic control pump displacement size by the deflection of swash plate, for meeting swash plate smooth rotation, need have developed a kind of crescent moon bearing with mutual wrong beam controllable type plastic-steel frame.
Summary of the invention
In view of the defect that prior art exists, the invention provides with mutual wrong beam controllable type crescent moon bearing, due to little installing space and oblique shallow bid deflection angle, devise selenodont bearing and be applied in this oil hydraulic pump; After swash plate repeatedly deflects, skid off raceway for preventing retainer assembly or cause shaft strength uneven, controlled linkage structure is designed at retainer end face, during swash plate deflection, the deflection angle of retainer is controlled, guaranteed that retainer assembly does not skid off raceway or produces shaft strength uneven phenomenon.
For achieving the above object, the technical solution adopted in the present invention is with mutual wrong beam controllable type crescent moon bearing, by retainer, roller and semi outer rings composition, design controlled linkage structure at retainer end face, controlled linkage structure is the groove with stiffening rib and blind hole, be installed to by straight pin in blind hole, straight pin is provided with hole, and seven sub-pins are through the hole of straight pin, seven sub-pin curved end are connected on swash plate, and vertically end is connected in the cotter pin of oil hydraulic pump.The pocket hole of described retainer is designed to square hole form, pocket hole is combined by two-part, and increase lock bridge at pocket hole internal diameter and external diameter position and control roller sag of chain, retainer is mutual wrong beam structure, its inner-diameter portion whose and outer radius portion misplace mutually, and overlap with semi outer rings and coordinate.The material of described retainer is plastic-steel.
After adopting such scheme, compared with prior art there is following beneficial effect: selenodont bearing has been applied in oil hydraulic pump, due to little installing space and oblique shallow bid deflection angle, retainer end face design linkage structure, retainer can be controlled, and retainer assembly can not skid off raceway or produce shaft strength uneven phenomenon; Cage bar adopts misplacement structure, is convenient to the mould production of plastic-steel frame and the shaping manufacture of plastic-steel frame.Special heat treatment mode, eliminates lasso internal stress, does not produce the distortion occurred due to stress relief when guaranteeing lasso Linear cut.

Embodiment
For understanding the structure with mutual wrong beam controllable type crescent moon bearing in depth, composition graphs 1 to Fig. 6 is described as follows:
With mutual wrong beam controllable type crescent moon bearing, by retainer 3, roller 4 and semi outer rings 1 form, design controlled linkage structure at retainer 3 end face, controlled linkage structure is the groove with stiffening rib and blind hole, is installed in blind hole by straight pin 5, straight pin 5 is provided with hole, seven sub-pins are through the hole of straight pin, and seven sub-pin curved end are connected on 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 square hole form, pocket hole is combined by two-part, and increase lock bridge 2 at pocket hole internal diameter and external diameter position and control roller sag of chain, retainer 3 is mutual wrong beam structure, its inner-diameter portion whose and outer radius portion misplace mutually, and overlap with semi outer rings 1 and coordinate.The material of described retainer 3 is plastic-steel.
The present invention has been applied in concrete mixer oil hydraulic pump, due to the swing effect of little installing space and bearing, in order to the output of accurate hydraulic control flow system flow, adopt 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 mutual shift, is convenient to the mould production of plastic-steel frame and the shaping manufacture of mass of plastic-steel frame.Special heat treatment mode, eliminates lasso internal stress, does not produce the distortion occurred due to stress relief when guaranteeing lasso Linear cut.
