Description
Technical field
The utility model relates to a kind of high-effect hydraulic full-balance floating buss, say more specifically as hydraulic system dynamical element and carry out the high pressure of original paper, at a high speed, the hydraulic gear oil pump of HI high impact and the axle sleeve of gear motor.
Background technique
Along with the development of machinery industry is more and more higher to the requirement of hydraulic system, current energy-conserving and environment-protective are main flow design concepts of whole hydraulic system; Be reflected on hydraulic element no matter as on the gear oil pump of dynamical element or the gear motor of executive component, not only require their volumetric efficiency high, also require that their mechanical efficiency is high and the life-span is long, being specifically reflected on gear oil pump and gear motor is exactly how to design a kind of axle sleeve or side plate can reach hydraulic full-balance; The disclosed a kind of high-effect hydraulic full-balance floating buss of the utility model development and Design under this background.
In prior art, as Fig. 2, axle sleeve 2 is along the symmetrical oil groove 2a of axle sleeve two side millings, although this structure can guide high pressure oil to low pressure area, and owing to being symplex structure, the full counterbalance effect that reaches axle sleeve so can not play hydraulic pressure to set up completely.
In prior art, as Fig. 2, the off-load that the front end face of axle sleeve 2 is offered is crossed oil groove 2b and from bush hole, is started complete milling to wear, although this structure can make the fluid of letting out in gear oil pump to taking filler opening to, but due to off-load, cross oil groove milling and wear and gear is contacted produce discontinuous with axle sleeve front end face, and cause gear movement not steady.
Model utility content
The utility model is the deficiency existing in above-mentioned prior art for avoiding, and provides a kind of high-effect hydraulic full-balance floating buss simple in structure, easy for installation, to improve the performance of gear oil pump and gear motor, reliability and working life.
The utility model is technical solution problem structural feature by the following technical solutions.
High-effect hydraulic full-balance floating buss, its structural feature is to comprise aluminium cover, lining and axle sleeve body; Described axle sleeve body be provided with two along axle sleeve body shaft to logical near the position of low pressure area and balancing slits, guide axle sleeve body back high pressure oil to the high-pressure reverse of gear oil pump and gear motor low pressure area to compensating groove, described axle sleeve body front end face is provided with two and is not exclusively through to the full balance oil groove of initiatively lubricating of low-pressure cavity; The positive outer periphery of described axle sleeve body is without the right angle form of chamfering.
It is described that initiatively to lubricate full balance oil groove be rectangle groove.
Compared with the prior art, the utility model beneficial effect is embodied in:
1) high-effect hydraulic full-balance floating buss of the present utility model is provided with two along axle sleeve body shaft to the high-pressure reverse near low pressure area to compensating groove on axle sleeve body, is provided with two and initiatively lubricates full balance oil groove on axle sleeve body front end face.High-pressure reverse makes high pressure oil enter low pressure one side by its guiding to compensating groove, in gear radial direction, give a reverse thrust, thereby reach radial equilibrium, make the gear shaft shoulder together with no longer fitting tightly between bush hole, and make lining and the gear shaft shoulder can set up effective oil film, effectively solved the easy heating problem of gear oil pump and gear motor; Make top circle and low pressure area place housing gear cavity sweep that hall amount reduces and even without sweeping hall, thereby further reduced the moment of torsion of gear oil pump and gear motor, and obtain higher mechanical efficiency, thereby reduced the specific energy consumption of main frame.At axial direction, make high-voltage oil liquid to compensating groove, enter the equal nip in the axle sleeve back side by high-pressure reverse, thereby make axle sleeve front reach balance with gear face, make the decrement of Sealing significantly reduce to become possibility, thereby the moment of torsion that has significantly reduced gear does not even have, and has improved volumetric efficiency.
2) in the utility model, initiatively lubricate the setting of full balance oil groove, make hydraulic leak fluid enter low pressure oil port by it, solved owing to leaking oil row and do not gone out the hydraulic shock producing, in leakage, be brought out simultaneously, can play again gear face and axle sleeve front end face are carried out to active lubrication, thereby improve the friction pair of gear face and end face of shaft bush; What the design of this groove made that gear face can be continuous at the front end face of axle sleeve fits together, can meet leakage oil can discharge and can make gear operation more to tend to be steady, thereby it is shock-resistant that gear oil pump and gear motor are had, and noise is low, the advantages such as life-span length.
3) high-effect hydraulic full-balance floating buss of the present utility model, has the advantages such as starting torque that raising gear oil pump and motor volumetric efficiency, gear oil pump and motor reduce gear oil working life.
