Problems solved by technology
This form of vane hydraulic motor is sealed by a contact line between the vane and the cylinder body, so the sealing performance is poor, the output torque is low, and there is a lot of friction between the vane, the rotor and the cylinder during rotation, resulting in the blade The overall wear of the hydraulic motor is fast, the life is short, and the efficiency is low
In addition, in order to ensure that the blades can safely enter and exit the rotor during rotation, the rotor must have a considerable diameter, which is bound to be large in size and low in specific power.

Embodiment Construction
[0036] Such as Figure 13 As shown, the shell oil-distributed cylindrical vane hydraulic motor of the present invention includes: a housing 1 , a rotor 2 , two vanes 3 , two sealing strips 4 and two pads 5 . The rotor 2 is located in the center, the housing 1 is located outside, and the two blades 3 are respectively located on both sides of the rotor 2, and are placed in the hollow ring (that is, the guide groove) at the opposite corner of the housing 1, forming an angle with the rotor 2, The tangent of the angle is the ratio of the height of the housing 1 to the diameter of the bottom circle of the housing 1 . A plane of the blade 3 is tangent to the side of the circular platform of the rotor 2, and the sealing strip 4 is located between the rotor 2 and the blade 3, and one side of the plane is attached to a plane of the rotor 2, and the cylindrical side is connected to the cylindrical surface of the blade 3 The E1 fits together, and the spacer 5 is located in the hollow rin...

The invention discloses a shell oil distribution type hydraulic motor with cylindrical vanes, comprising a shell, a rotor, two vanes, two sealing strips and two gaskets; the rotor is arranged in the center, the shell is arranged at the outer part, the two vanes are respectively arranged at two sides of the rotor and placed in hollow circular rings at across corners of the shell to form a certain angle with the rotor, and the tangent value of the angle is equal to the ratio of the height of the shell to the diameter of a bottom circle of the shell; the sealing strips are arranged between the rotor and each of the vanes, the plane side of each sealing strip is jointed with one plane of the rotor, the cylindrical surface side of each sealing strip is jointed with the cylindrical surface E1 of each vane, and the gaskets are arranged in the hollow circular rings at the across corners of the shell to just fill in a gap formed by the vanes, the rotor and the sealing strips. Sealing parts of the shell oil distribution type hydraulic motor with the cylindrical vanes are all in surface sealing, and the shell oil distribution type hydraulic motor with the cylindrical vanes has the advantages of high efficiency, high specific power, large output torque, compact structure and long service life.
Description
technical field [0001] The invention relates to a hydraulic motor, in particular to a shell oil distribution type cylindrical vane hydraulic motor. Background technique [0002] The structure of the existing vane hydraulic motor is that the rotor is eccentrically placed in the oil cylinder body, and the blades are placed in the rotor radially or at a certain angle with the rotor radius. Form a sealed cavity. This form of vane hydraulic motor is sealed by a contact line between the vane and the cylinder body, so the sealing performance is poor, the output torque is low, and there is a lot of friction between the vane, the rotor and the cylinder during rotation, resulting in the blade The overall wear of the hydraulic motor is fast, the life is short, and the efficiency is low. In addition, in order to ensure that the blades can safely enter and exit the rotor during rotation, the rotor must have a considerable diameter, which inevitably leads to large volume and low specifi...
