Abstract
The utility model relates to a variator, in particular to a hydraulic stepless variator which is composed of a machine bracket. The machine bracket is provided with an oil pool and a hydraulic pump; wherein the hydraulic pump is connected to a hydraulic motor via a direction turning valve pipeline and then form a stepless variation mechanism. When in application, a speeding up motor and a hydraulic pump is transmittingly connected; an output rev of the hydraulic motor is adjusted by adjusting pressure and flow of the hydraulic motor outputting hydraulic oil, so as to complete non stage speed up.
Description
Technical field: the utility model relates to a kind of variable-speed motor, particularly a kind of stepless speed changer.
Background technique: all use stepless speed changer on present many equipment, the structure of variable-speed motor general using mechanical friction type or electromagnetic type is carried out stepless speed regulation, but the stepless speed changing mechanism of these modes can not permanent power work in rotating speed and change in torque, and the efficient of transmission is not high, and noise is big.
Summary of the invention: at the deficiencies in the prior art, the utility model provides a kind of hydraulic stepless speed changes machine that can permanent power work.
The utility model comprises the frame of being with oil sump, and frame is provided with oil hydraulic pump, and this oil hydraulic pump connects oil hydraulic motor by the selector valve pipeline and constitutes stepless speed changing mechanism.
In use will need the motor of speed change and oil hydraulic pump to be in transmission connection, the pressure of the hydraulic oil by regulator solution press pump output and the output speed that flow comes the regulator solution pressure motor can carry out stepless change.The pressure and the flow of the hydraulic oil of oil hydraulic pump output are inversely proportional to, and the utility model can permanent power work like this, and the speed change that can have a machine in operation is steady, and speed governing is accurate, and noise is little, the transmission efficiency height.
Further specify the utility model below in conjunction with drawings and Examples.
Description of drawings: Fig. 1 is embodiment's a main structure schematic representation;
Fig. 2 is the circuti diagram that embodiment's hydraulic pressure connects.
Embodiment: as shown in the figure, frame 1 is provided with oil sump 6, is provided with oil hydraulic pump 2 on frame 1, and this oil hydraulic pump 2 connects oil hydraulic motor 4 by selector valve 3 pipelines and constitutes stepless speed changing mechanism.During use, to need the motor 7 and the oil hydraulic pump 2 of speed change to be in transmission connection, the pressure of the hydraulic oil by regulator solution press pump 2 output and flow can step-less adjustment oil hydraulic motor 4 output speed, by 3 flow directions that can control hydraulic oil of selector valve, make the change that turns to of oil hydraulic motor 4.The pipeline of present embodiment between oil hydraulic pump 2 and selector valve 3 also connects oil sump 6 by relief valve 5 bypasses and constitutes over-pressure safety device, and hydraulic oil can overflow in the oil sump 6 through relief valve 5 when pressure was excessive like this.
