Abstract
The utility model relates to a hydraulic variable motor rotary planet speed reduction machine capable of braking, belonging to the technical field of the rotary engineering machine. The utility model is characterized in that a brake mechanism which is composed of a spring, a piston, a friction plate and an oil hole is arranged in a cylinder sleeve motor base of the rotary speed reduction machine. The spring is normally closed to support and brake the friction plate, and a hydraulic variable displacement motor with a control valve is also arranged in the cylinder sleeve motor base. When motive power is driven to drive a spline housing to move, pressure oil liquid from 18 kg to 23 kg is injected in a stopper, oil pressure pushes the piston to move toward a hole gear spacer direction, the friction plate loses pressure, and the rotary speed reduction machine works. The utility model has the advantages of convenient operation, long service life and large output torque; the utility model is reliable and flexible to be braked, is tightly locked and is orientated correctly; the utility model is the novel rotary braking device of the rotary support engineering machine.
Description
But the utility model relates to a kind of brake fluid pressure variable-dis-placement motor rotary planetary reductor of engineering machinery field.
Domestic existing construction machinery and equipment, hanging with other as excavating machine, wheel crane, harbour needs rotary reducer itself band brake not on the construction machinery and equipment of pivoting support, thereby do not have a braking function, and the shoe brake that adopts separately, brake material is wherein made around knot by moulding fat, asbestos, copper wire etc., wear and tear easily in the use, peel off, can not be durable in use, it is big that brake moves sliding property, directed being difficult to accurately, mechanical breakdown frequency height, machine volume is big, heavy, poor-performing, also need dispose hydraulic pressure.
The purpose of this utility model is at above-mentioned deficiency, it is one that a kind of braking, HM Hydraulic Motor, reductor are provided, have that output torque is big, load-carrying capacity is strong, but reliable in mechanical performance, directed accurately, brake fluid pressure variable-dis-placement motor rotary planetary reductor that the space occupy-place is few.
The purpose of this utility model is achieved through the following technical solutions: but a kind of brake fluid pressure variable-dis-placement motor rotary planetary reductor that comprises cylinder sleeve motor seat and rotary planetary reductor, it is characterized in that the ring washer top in cylinder sleeve motor seat is provided with the internal toothed friction plate and the external tooth friction lining of stack successively, the top of friction lining is provided with piston, be processed with some axial blind holes on the piston, all be equipped with spring in the hole, spring top is pushed down by hole shelves pad, locate with the hole shelves top of hole shelves pad and cylinder sleeve motor seat hole wall junction, cylinder sleeve motor seat lateral surface one place is processed with the oilhole that communicates with nearly blind hole below piston, the lateral surface aperture is through the fixing plug of screw thread, insert hydraulic variable motor in the cylinder sleeve motor seat, the output shaft of hydraulic variable motor output end face inserts the interior engagement of spline housing of rotary planetary reductor, the control cock of hydraulic variable motor setting is injected swash plate after with the hydraulic oil variable, and spline housing directly is connected with primary planet carrier; The internal tooth of internal toothed friction plate and spline housing engagement, the axial splines groove engagement of the external tooth of external tooth friction lining and cylinder sleeve motor seat inwall; The gap that nearly 3mm is arranged when no oil pressure between piston and the hole shelves pad.
The utility model is designed to one with hydraulic variable motor, rotary reducer and new brake structure, by the stepless change automatic guidance to the plunger pump delivery rate, the CD-ROM drive motor running, compact conformation is reasonable, easy to operate, braking and locking is reliably flexible, and is accurately directed, long service life, output torque is big, has saved the complete machine raw MAT'L, greatly reduces manufacturing cost, having high economic benefit and social benefit, is pivoting support construction machinery and equipment a new generation rotary braking equipment.
Accompanying drawing is the utility model structural representation.
In the accompanying drawing: the 1st, cylinder sleeve motor seat, the 2nd, hole shelves pad, the 3rd, piston, the 4th, plug, the 5th, blind hole, the 6th, spring, the 7th, interior external tooth friction lining, the 8th, spline housing, the 9th, oilhole, the 10th, hole shelves, the 11st, ring washer, the 12nd, primary planet carrier, the 13rd, lower house, the 14th, hydraulic variable motor, the 15th, control cock, the 16th, swash plate, the 17th, multilayer piston, the 18th, output shaft.
Further specify the utility model in conjunction with the accompanying drawings and embodiments.Oilhole 9 below the processing of one place, the outside of rotary planetary reductor cylinder sleeve motor seat 1 can be led to piston 3 nearly blind holes 5, the aperture of lateral surface is through the fixing plug 4 of screw thread, rectangular distribution is processed some axial blind holes on piston 3, equal inserting spring 6 in each hole, hole shelves pad 2 pressing springs 6, when no oil pressure, the gap that keeps nearly 3mm between hole shelves pad 2 and the piston 3, locate with hole shelves 10 top of hole shelves pad 2 and cylinder sleeve motor seat 1 hole wall junction, internal toothed friction plate in the friction lining 7 and external tooth friction lining superpose successively and place the top of ring washer 11, piston 3 is pushed down friction lining 7 under the effect of spring 6, stiff between the interior external tooth friction lining, and block spline housing 8 and cylinder sleeve motor seat 1 inwall axial splines groove separately, this moment, rotary reducer was in braking mode.Insert hydraulic variable motor 14 in the cylinder sleeve motor seat 1, the output shaft 18 of hydraulic variable motor 14 output end faces inserts the spline housing 8 interior engagements of rotary planetary reductor, the control cock 15 that hydraulic variable motor 14 is provided with is injected swash plate 16 after with the hydraulic oil variable, swash plate 16 back and forth continuous translation-angles, promote multilayer piston 17, thereby reaching variable drives output shaft 18 runnings and drives spline 8 runnings, spline housing 8 directly is connected with primary planet carrier 12, lower house 13 is fixed on the stand of turning engineering machinery, when driving 8 actions of power drive spline housing, earlier behind the pressure oil liquid injection plug 4 with 18～23kg, oil pressure promotes piston 3 and moves to hole shelves pad 2 directions, at this moment, friction lining loses pressure, and is loosening between the interior external tooth friction lining 7, and internal toothed friction plate rotates with spline housing 8, rotary reducer work, whole cranking time was no more than for 15 seconds.
