Abstract

The utility model relates to an extruding type elastic shaft coupling, belonging to a connecting element for the power output of engineering machinery or transport machinery. The utility model is characterized in that a driving wheel (2) is in an inner cross shape, a driven wheel (5) is in an outer cross shape, and eight cylindrical rubber rods (3) are clamped between the driving wheel (2) and the driven wheel (5), so the utility model is made to realize the transmission of a dynamic force with large power and torsional moment. The extruding type elastic shaft coupling has the advantages of long service life, good vibration damping performance, simple processing technology and low cost.

Description

Extruding type elastic shaft coupling

The utility model belongs to the linkage member of engineering machinery or the output of Transport Machinery power.

The driven wheel of existing elastic coupling flexible coupling is to be to be pressed in the seam of driving wheel after overall sulfur changes into one with rubber, by the frictional force transmitting torque of rubber, thus have the transmission, processing technology complexity, the reject rate height that are not suitable for high-power moment of torsion, working life is short, cost is high and problem such as damping property difference.

The purpose of this utility model is that a kind of high-power moment of torsion, long service life, damping property is good and cost is low extruding type elastic coupling flexible coupling of transmitting will be provided.

Technological points of the present utility model is that driving wheel is processed into interior cross, driven wheel is processed into outer cross, between driving wheel and driven wheel, accompany 8 columniform rubber rods, driving wheel and driven wheel are by the extruding transmitting torque, be difficult for skidding, thereby can make the utility model realize to transmit high-power moment of torsion, long service life, the effect that damping property is good and cost is low.

Extruding type elastic coupling flexible coupling of the present utility model is as depicted in figs. 1 and 2: be to be skeleton with driving wheel (2) and driven wheel (5), its driving wheel (2) is interior cross, driven wheel (5) is outer cross, between driving wheel (2) and driven wheel (5), accompany 8 columniform rubber rods (3), the front portion of rubber rod (3) is fixing by plate washer (4) and driven wheel (5), driven wheel (5) is by flywheel center hole (8) and seat (1) supporting, the centre has bearing (7) to connect, and bearing (7) is fixing by bearing cap (6).

Working principle of the present utility model is: driving wheel is contained on the engine flywheel, input power, pass to driven wheel by rubber rod, outputting power makes automobile running, because the utility model is by the extruding transmitting torque, be difficult for skidding, therefore can transmit high-power moment of torsion, damping property is good, travels steadily.

Extruding type elastic coupling flexible coupling of the present utility model is bigger than the power that existing friction type elastic coupling flexible coupling transmits, and damping property is good, long service life, and cost is low, and processing technology is simple.
