Description
Technical field
The utility model relates to the hydraulic system field, be specifically related to a kind of novel tilt cylinder type hydraulic motor.
Background technique
Oil hydraulic motor refers to traditionally to export and rotatablely moves, and the hydraulic energy that oil hydraulic pump is provided changes the energy conversion device of mechanical energy into.Oil hydraulic motor also is called oil motor, is mainly used in injection machine, boats and ships, rises and raise machine, engineering machinery, building machinery, coal mine machinery, mining machinery, metallurgical machinery, ship machinery, petrochemical industry, harbour machinery etc.Oil hydraulic motor can be divided into high-speed hydraulic motor and low speed high torque hydraulic motor by its rotating speed and moment of torsion; The mode of action by oil hydraulic motor can be divided into multiaction oil hydraulic motor and single-acting oil hydraulic motor; Can be divided into plunger type, gear type and vane motor etc. by its structural type.
Radial piston hydraulic motor is a kind of as low speed high torque hydraulic motor, owing to the occasion that its speed range is large, moment of torsion high, low speed good stability is widely used in directly driving load, such as metallurgical machinery, plastics machinery and mining machinery etc.The only single shaft output of traditional tilt cylinder type hydraulic motor, and can not fit well between plunger and the crankshaft support cover, cause this to occurring leakage between the friction pair, reduced the volumetric efficiency of oil hydraulic motor; Also reduced the mechanical efficiency of motor.
The model utility content
For the deficiency that exists on the prior art, the utility model purpose is to be to provide a kind of novel tilt cylinder type hydraulic motor, and it has improved the oil hydraulic motor starting characteristic, improves starting torque, strengthen the ability of opposing thermal shock, and then prolong the working life of fluid distribution of hydraulic motor system.
To achieve these goals, the utility model is to realize by the following technical solutions: it comprises housing, bent axle, cylinder cap, tilt cylinder, plunger, the plunger return spring, driving gear, double-end key, driven gear, thrust plate, auxiliary flow side plate, wavy spring and flow housing, the middle part of bent axle is socketed with plunger by the crankshaft support cover, the plunger arranged outside has the plunger return spring, plunger return spring arranged outside has tilt cylinder, tilt cylinder is outside equipped with cylinder cap, the cylinder cap outer installment has housing, fixed cover is connected to driving gear on the bent axle of plunger right-hand member, driving gear passes through double-end key, driven gear matches with thrust plate, thrust plate one side is provided with auxiliary flow side plate, and auxiliary flow side plate matches with the flow housing by wavy spring.
Adopt roll structure between described crankshaft support cover and the bent axle.
Adopt ball pivot to connect between described cylinder cap and the tilt cylinder.
The utility model has improved the oil hydraulic motor starting characteristic, improves starting torque, strengthens the ability of opposing thermal shock, and then prolongs the working life of fluid distribution of hydraulic motor system.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is structural representation of the present utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
With reference to Fig. 1, this embodiment is by the following technical solutions: it comprises housing 1, bent axle 2, cylinder cap 3, tilt cylinder 4, plunger 5, plunger return spring 6, driving gear 7, double-end key 8, driven gear 9, thrust plate 10, auxiliary flow side plate 11, wavy spring 12 and flow housing 13, the middle part of bent axle 2 is socketed with plunger 5 by crankshaft support cover 14, plunger 5 arranged outside have plunger return spring 6, plunger return spring 6 arranged outside have tilt cylinder 4, tilt cylinder 4 is outside equipped with cylinder cap 3, cylinder cap 3 outer installment have housing 1, fixed cover is connected to driving gear 7 on the bent axle 2 of plunger 5 right-hand members, driving gear 7 is by double-end key 8, driven gear 9 matches with thrust plate 10, thrust plate 10 1 sides are provided with auxiliary flow side plate 11, and auxiliary flow side plate 11 matches with flow housing 13 by wavy spring 12.
It is worth mentioning that, adopt roll structure between described crankshaft support cover 14 and the bent axle 2; This roll structure is converted into rolling friction with sliding friction, can significantly reduce frictional heating and improve the mechanical efficiency of oil hydraulic motor.
And, adopt ball pivot to connect between described cylinder cap 3 and the tilt cylinder 4.Ball pivot connect can eliminate fully tilt cylinder 4 and plunger 5 this to the lateral force between the friction pair, can improve the mechanical efficiency of motor and improve the starting torque of oil hydraulic motor.Simultaneously, the ball pivot design between tilt cylinder and the cylinder cap also can make between plunger and the crankshaft support cover better fits, and reduces this to the leakage between the friction pair, thereby improves the volumetric efficiency of oil hydraulic motor.
The working principle of this embodiment is: high-voltage oil liquid enters plunger 5 by thrust plate 10, position according to thrust plate is different, high pressure oil enters two or three adjacent plungers and promotes bent axle 2 rotations, bent axle rotarily drive driving gear 7, and drive thrust plates by driven gear 9 and double-end key 8 and make synchronous rotary, thereby realized continuous flow, so oil hydraulic motor just can form continuous moment of torsion output.
This embodiment has been improved the oil hydraulic motor starting characteristic, improves starting torque, strengthens the ability of opposing thermal shock, and then prolongs the working life of fluid distribution of hydraulic motor system.
Above demonstration and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
