Abstract
The utility model discloses a novel wobble plate used for a hydraulic plunger pump or a hydraulic motor. A groove structure in which hydraulic oil flows is arranged on a plane where the wobble plate is in contact with a thrust plate. The groove structure comprises at least one concentric circular groove and at least one connecting groove, and the connecting groove is communicated with the concentric circular groove, and an opening at one end of the connecting groove is formed on the peripheral edge of the wobble plate. According to the utility model, hydraulic oil flows on the plane where the wobble plate is in contact with the thrust plate, cold and hot convection circulation can be realized, the local temperature of the wobble plate is reduced, temperature at two sides of the thrust plate in contact with the wobble plate is uniform, thus avoiding failure and damage caused by material deformation if the local part is heated seriously.
Description
Technical field
The utility model belongs to hydraulic planger pump (oil hydraulic motor) structure-design technique field, is specifically related to a kind of novel balance that is used for hydraulic planger pump or oil hydraulic motor.
Background technique
As shown in Figure 1, the differential balance 1` in existing hydraulic planger pump or the oil hydraulic motor also is to receive force supporting device usually as variable device, and the one of which side is plunger oil suction (going into an oil) low voltage side, and is stressed little low with heating; Opposite side then bears high pressure bump, and is stressed big high with heating, makes the local temperature of balance too high, causes the thrust plate variable color that contact with the one of which side plane, surface strength reduction.
The model utility content
The purpose of the utility model is the deficiency to existing technology, and a kind of novel balance simple in structure is provided, and it is used for hydraulic planger pump or oil hydraulic motor, can solve the too high problem of local temperature of balance.
For achieving the above object, the utility model adopts following technological scheme:
Offer the groove structure that feed flow is pressed oil flow on the novel balance that is used for hydraulic planger pump or oil hydraulic motor, said balance and plane that thrust plate contacts.
As preferably, said groove structure comprises at least one annular concentric groove and at least one connecting groove, and said connecting groove is communicated with said annular concentric groove and one of which end slot interruption-forming on the periphery of balance.
Further preferred, the cross section of said annular concentric groove and connecting groove is rectangle.
As preferably, the integrally formed swing arm of a side of said balance.Further preferred, said balance and swing arm are the cast inblock structure.
The utility model is through adopting said structure; Hydraulic oil is flowed on balance and plane that thrust plate contacts; Realize cold and hot convection circulation; Reduce the local temperature of balance, make that the thrust plate both sides temperature of contact is even with it, avoid causing the phenomenon generation of losing efficacy and damaging because of local pyrexia seriously causes material deformation.And adopting the cast inblock structure with the balance of one-sided swing arm, structural strength is high, carries greatly, swing reliable and stablely, is prone to realize multi-functional control, suitable heavily loaded high-pressure large-displacement pump.
Description of drawings
Fig. 1 is the structural representation of existing differential balance.
Fig. 2 is the plan structure schematic representation of the utility model.
Fig. 3 is the sectional structure schematic representation of the utility model.
Fig. 4 is the sectional structure schematic representation that has adopted the hydraulic planger pump of the utility model.
Among the figure:
The differential balance of 1`-; The 1-balance; 11-annular concentric groove; The 12-connecting groove; The 13-swing arm; The 2-thrust plate; The 3-hydraulic planger pump.
Combine accompanying drawing and embodiment that the utility model is done further explain at present.
Embodiment
Like Fig. 2 to shown in Figure 3, the described novel balance 1 of the utility model, its with plane that thrust plate contacts on offer the groove structure of feed flow pressure oil flow.This groove structure is made up of an annular concentric groove 11 and four connecting grooves 12, and every connecting groove 12 is communicated with said annular concentric grooves 11 and one of which end slot interruption-forming on the periphery of balance 1.The cross section of annular concentric groove 11 and connecting groove 12 is rectangle.In addition, the integrally formed swing arm 13 of a side of balance 1, this swing arm 13 is the cast inblock structure with balance 1.
As shown in Figure 4, the novel balance 1 of the utility model is assembled in the hydraulic planger pump 3.During hydraulic planger pump 3 work; Hydraulic oil is the automatic circulation heat radiation in annular concentric groove and connecting groove; Make the low voltage side and the on high-tension side temperature of balance even, thereby the thrust plate of avoiding contacting with it 2 cause the phenomenon of variable color, surface strength reduction to take place because of local temperature is too high.And the cast inblock processing structure of the one-sided band swing arm of balance leans on the locating stud location on the concentric circle of both sides, swing reliable and stablely, is prone to the realization multi-functional control; And structural strength is high, carries greatly, is suitable for heavily loaded high-pressure large-displacement pump.
The quantity that should be noted that the annular concentric groove of the utility model is not limited to one, and its quantity should be set according to the hydraulic planger pump performance design parameter of reality.
Claims (5)
1. be used for the novel balance of hydraulic planger pump or oil hydraulic motor, it is characterized in that, offer the groove structure that feed flow is pressed oil flow on said balance and the plane that thrust plate contacts.
2. novel balance according to claim 1 is characterized in that, said groove structure comprises at least one annular concentric groove and at least one connecting groove, and said connecting groove is communicated with said annular concentric groove and one of which end slot interruption-forming on the periphery of balance.
