Abstract
The invention designs a driving belt pulley shaft which mainly comprises an input end and a belt pulley surface. The input end is arranged at the rear part of the belt pulley surface. The front part of the belt pulley surface is provided with a belt pulley installation section. The front part of the belt pulley installation section is provided with a belt pulley control section. The diameter of the belt pulley installation section is greater than that of the belt pulley control section. Oil circuit ports are uniformly distributed on the end face of the belt pulley installation section. Oil circuit grooves are arranged on the belt pulley control section. The positions of the oil circuit grooves are matched with the positions of the oil circuit ports. The oil circuit grooves are in transition with the outer surface of the belt pulley control section through planes, so that the cross section areas of oil circuits are increased. The driving belt pulley shaft has reasonable structure design. The oil circuit ports are arranged on the end face of the belt pulley installation section, so that the length of the belt pulley control section is reduced, and thus, the length of the complete driving belt pulley shaft is reduced. On the other hand, innovatively, the oil circuit grooves on the belt pulley control section are in transition with the outer surface of the belt pulley control section through the planes, so that the cross section areas of oil circuits are increased and the control force is improved.
Description
Technical field
The present invention relates to a kind of belt shaft, particularly a kind of driving pulley axle.
Background technique
Belt shaft is a kind of driving mechanism, and the driving pulley axle cooperates with driving pulley, regulates effective transmission circumference through the spacing between two belt wheel faces of hydraulic oil control, thereby reaches the purpose of regulating the output ratio.Existing driving pulley axle design is unreasonable, in order to reach the output ratio control of design demand, has designed long oil circuit, makes that the axial length of driving pulley axle is longer, has increased difficulty of processing and man-hour, has also caused the waste of material.
Summary of the invention
The objective of the invention is provides a kind of oil circuit short for the deficiency that solves above-mentioned technology, and can effectively control the driving pulley axle of two belt wheel interplanar distances.
In order to achieve the above object, the driving pulley axle that the present invention designed, it mainly comprises input end and belt wheel face; Input end is arranged on the rear portion of belt wheel face, and the front portion of belt wheel face is the belt wheel construction section, and the front portion of belt wheel construction section is the belt wheel control section; The diameter of belt wheel construction section is greater than the belt wheel control section; And on the end face of belt wheel construction section, be evenly equipped with the oil circuit mouth, on the belt wheel control section, be provided with and the oil circuit groove, the position of described oil circuit groove cooperates with the position of oil circuit mouth.The characteristics of this structure are that the inlet opening with oil circuit is arranged on the belt wheel construction section, have effectively saved the length of belt wheel control section.
On the other hand, in order to improve the control force of hydraulic oil, the outer surface of described oil circuit groove and belt wheel control section is through the plane transition, thus the cross-section area of increase oil circuit.
The resulting driving pulley Structural Design of Shaft of the present invention is reasonable, the oil circuit mouth is arranged on the end face of belt wheel construction section, thereby has reduced the length of belt wheel control section, and then reduced the length of whole driving pulley axle.On the other hand, the outer surface with oil groove on the transition pulley control section of plane and belt wheel control section of innovation increases the oil circuit cross-section area, has improved control force.In sum, this driving pulley axle has, and cost of production is low, and economical with materials is controlled effective advantage.
