Abstract

The utility model discloses a point-contart internal drainage hydraulic starting dynamo, composed of an end cover, a cylinder body, a dynamo body, a plunger, a rotary shaft and a sealing ring, etc. The utility model is characterized in that high-pressure oil pushes the plunger to work by the work of rotating an oil distributing valve, therefore, passing through the output power of the rotary shaft, adopting an inner leak type oil drainage structure, the utility model has the advantages of compact structure, shock resistance, small starting inertia and big output power, and the dynamo is a new-type hydraulic starting dynamo of an anti-bursting diesel engine.

Description

Point-contart internal drainage hydraulic starting dynamo

Axis point contact internal drainage type hydraulic starter relates to the mechanical-hydraulic transmission field, especially the oil motor field.

Now general oil hydraulic motor, structure is the non-shaft type piston motor of piston shoes crawler shoe, not shock-resistant, its rotating speed is in 2000～3000rpm, though discharge capacity is 10 milliliters miniature motor rotating speed Gao Keda 4000rpm, but moment of torsion is little, and is not shock-resistant, so also not can be used in the piston motor of the special operation condition of explosion-proof locomotive starting.The starter motor of Britain is a gear motor, changes scooter 6500rpm, can not surpass 140Kg/Cm but bear pressure ², discharge capacity is 25 milliliters/commentaries on classics.

The purpose of this utility model has provided a kind of axis axial plunger point contact internal drainage type motor, can bear pressure 200Kg/Cm ², rated speed 3000rpm reaches as high as 5200rpm.Maximum speed can reach 6000rpm.Shock-resistant, the life-span is long, and discharge capacity is 26 milliliters/commentaries on classics, is well suited for the explosion-proof locomotive hydraulic starting.

The utility model is to realize like this, form by end cap, packing ring, cylinder body, plunger, seal ring, swash plate, running shaft, motor body etc., in motor, have nine plungers, plunger contact with swash plate be spherical some contact, the moving direction of plunger be running shaft axially on to-and-fro motion.End at running shaft has an eccentric shaft, and eccentric shaft drives and revolves a guiding valve, and high pressure oil is supplied with each plunger work respectively successively.One internal drainage hole is arranged in cylinder body, make that internal leakage oil is humorous together discharges cylinder body with the inner oil extraction of motor, to realize the purpose of internal drainage type.

It shown in the accompanying drawing structural representation of the present utility model.

The drawing explanation:

End cap (1), revolve unload in shafting oil valve (2), packing ring (3), the body oilhole (4), cylinder body (5), plunger (6), motor body (8), in divulge a secret seal ring (9), running shaft (10), key (11), eccentric shaft (12).

Below with reference to the accompanying drawings, the utility model is described in further detail:

After high pressure oil enters from the oil inlet hole on the end cap, enter an end of plunger by revolving valve (2), the promotion plunger moves upward, withstand swash plate (7), owing to produce tangential force on the swash plate, rotate by key (11) driven rotary axle (10), produce moment of torsion, and the eccentric shaft (12) of axle (10) one ends is driven rotary guiding valves, and the rotation of revolving valve is about to high pressure oil and in turn supplies with each plunger respectively, makes each plunger working in reciprocating mode successively, and realize, oil outlet is separately joined oil, motor is constantly rotated, and output power and moment of torsion reach the purpose of starting explosion-proof locomotive.

Of the present utility model to revolve axle axle (10) be an axis, and eccentric shaft (2) is the integral body that connects together, and cylinder body (5) is fixed on the motor body (8) and does not rotate, by running shaft (10) output motor power.On cylinder body, be provided with the internal drainage hole, seepage oil is external by oil drainage hole discharge motor with the inner oil extraction of motor in making, internal drainage is unlikely to be spilt in order to make, the seal ring of in the other end of motor body (8) is provided with, divulging a secret (9), and locate to be provided with a packing ring (3) at revolving valve (2), can make the revolving valve rotation flexibly, unlikely again leakage high pressure oil.

The output torque that is also advantageous in that of the present utility model is even, withstand shock, and good seal performance and structure are tightly played, and are applicable to particular job environment.

Claims

1, axis point contact internal drainage type hydraulic starter, form by end cap, packing ring, cylinder body, plunger, seal ring, swash plate, running shaft, motor body, it is characterized in that having nine plungers, plunger is that spherical point contacts with the swash plate point of contact, end at running shaft has an eccentric shaft, eccentric shaft driven rotary guiding valve is supplied with each plunger work respectively successively with high pressure oil, and an internal drainage hole is arranged in cylinder body.
