Abstract
The invention provides a two-angle-rotor hydraulic motor. The two-angle-rotor hydraulic motor is an apparatus which uses hydraulic energy output by a hydraulic pump to push an oval rotor to rotate in a cylinder body so as to convert the hydraulic energy into mechanical energy for work. The motor has the characteristics of high efficiency, high torque, micro-vibration, low noise, a small size, light weight, a high rotating speed, good sealability, etc., so other pump machines are incomparable with the motor; and the motor needs low manufacturing cost and has wide market prospects.
Description
Technical field
The invention belongs to energy power conversion device, particularly a kind of design implementation method of oval two-angle rotor oil hydraulic motor that hydraulic energy changes mechanical energy into.
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.Be mainly used in injection machine, boats and ships, rise and raise machine, engineering machinery, building machinery, coal mine machinery, mining machinery, metallurgical machinery, ship machinery, petrochemical industry, harbour machinery etc.
Oil hydraulic motor divides by its structure type can be divided into gear type, blade type, plunger type etc.Rated speed by oil hydraulic motor is divided at a high speed and low speed two large classes.Rated speed is higher than the high-speed hydraulic motor that belongs to of 500r/min, and rated speed is lower than the low speed hydraulic motor that belongs to of 500r/min.The basic pattern of high-speed hydraulic motor has gear type, screw type, blade type and axial piston etc.Their main feature is that rotating speed is higher, rotary inertia is little, be convenient to start and braking, to regulate (speed governing and commutation) highly sensitive.So high-speed hydraulic motor output torque not quite is called again the little torque fluid pressure motor of high speed usually.The basic pattern of low speed hydraulic motor is radial plunger type, the structural type that low speed is also arranged in this external axial piston, blade type and the gear type, the main feature of low speed hydraulic motor are that discharge capacity is large, the large rotating speed of volume low (sometimes can reach per minute several turn in addition zero point several turning), therefore can directly be connected with operation mechanism; Do not need speed reducer, driving mechanism is greatly simplified, low speed hydraulic motor output torque is larger usually, so be called again the low speed high torque oil hydraulic motor.
The vane motor volume is little, rotary inertia is little, be active in one's movements, applicable to the higher occasion of commutating frequency; But leakage rate is large, unstable during tick-over.Therefore vane motor generally is used for the occasion that rotating speed is high, torque is little and action request is sensitive.
Summary of the invention
The present invention relates to a kind of oval two-angle rotor oil hydraulic motor, mainly by comprising oval two-angle rotor, cylinder body, inside and outside gear, eccentric shaft, support shoulders, the support shoulders ring, bearing, balancing weight, front and rear cover advances, the composition such as liquid port.The molded line of two-angle rotor is elliptical shape, and the molded line of cylinder body is rotor theory shaped wire envelope curve line.External gear is fixed on the end cap, and internal gear is fixed on the end face of two-angle rotor, and external gear is 1: 2 with internal gear number of teeth ratio.Cylinder body and two-angle rotor surface are provided with seal ring in the contacting point forever, and pump chamber is divided into two working rooms.On cylinder body or front and rear cover have into, liquid port.Whole in operation, for smooth running, at the two-angle rotor two ends lightening hole is arranged, and at the eccentric shaft two ends balancing weight is installed and carries out counterweight.
The two-angle rotor oil hydraulic motor is to utilize the volume-variation of active chamber to come work done, has high moment of torsion, little vibration, and low noise, volume are little, lightweight, the rotating speed high, this is that other pump machine products are incomparable, low cost of manufacture is easy to produce, and has wide market prospects space.
Description of drawings
Fig. 1 is two-angle rotor oil hydraulic motor schematic diagram.1. external gear, 2. internal gear, 3. oval two-angle rotor, 4. cylinder body, 5. output shaft, 6. eccentric wheel.Two-angle rotor 3 is housed in the pump housing, and output shaft 5 is installed on the eccentric wheel 6, and eccentric wheel 6 and two-angle rotor 2 are installed together.
Embodiment
Working procedure is as follows: the hydraulic energy that oil hydraulic pump provides enters corresponding seal operation space by liquid entering hole and acts on the oval two-angle rotor, because oval two-angle rotor is eccentric, just produced torque differences, thereby promote the two-angle rotor rotation, drive output shaft rotation acting, the liquid after the work done is discharged by liquid port again.If change the hydraulic energy input direction, then can change turning to of rotor.
Claims (3)
