Embodiment Construction

[0018] The extrusion and torsion composite elastic coupling in this embodiment includes an input disc 1, an output disc 2, an extruded rubber block 3 and a torsion transmission assembly;

[0019] The input disk 1 is provided with an arc-shaped groove 1a extending along its circumferential direction, the number of the arc-shaped grooves 1a is four and evenly arranged along the circumferential direction of the input disk 1, and the extruded rubber block 3 is arranged in the arc-shaped groove In 1a, the output disk 1 is provided with a protrusion 2a that extends into the arc-shaped groove 1a and can move along the arc-shaped groove; When the pressing rubber block 3 rotates to contact with the bump 2a on the output disc 2, the pressing rubber block 3 will push the bump 2a to rotate, thereby transmitting the power from the input disc 1 to the output disc 2;

[0020] The torsion transmission assembly includes a torsion rubber sleeve 4, a first transmission piece 5 fixedly connected ...

Abstract

The invention discloses a squeezing and twisting combined-type elastic coupler, which comprises an input disc, an output disc, a squeezing rubber block and a twisting transmission assembly; the input disc is provided with an arc groove extending along the circumferential direction, the squeezing rubber block is arranged inside the arc groove, and the output disc is provided with a projection which stretches into the arc groove and can move along the arc groove; and the twisting transmission assembly comprises a twisting rubber sleeve, a first transmission sheet and a second transmission sheet, and two ends of the twisting rubber sleeve are respectively and fixedly connected with the first transmission sheet and the second transmission sheet. The power is transferred from the input disc to the output disc through the twisting transmission assembly and the squeezing rubber block, so that the squeezing and twisting combined-type elastic coupler can compensate the angular displacement error of a transmission shaft system because of the twisting deformation of the twisting rubber sleeve; and meanwhile, since both the twisting rubber sleeve and the squeezing rubber block have the buffering shock absorption function, the squeezing and twisting combined-type elastic coupler has advantages of low transmission noise, small vibration, long service life and the like.

Description

technical field [0001] The invention relates to a transmission connecting piece in the mechanical field, in particular to a highly elastic coupling. Background technique [0002] Elastic coupling is an important part connecting the power device and the drive system. According to the classification of elastomer materials, it can be divided into metal type and rubber type. Due to the characteristics of high rigidity, high hardness, and weak impact resistance of metal materials, it often causes problems in the transmission system such as vibration, noise, impact, poor reliability, and short life. Disadvantages of angular displacement. In order to solve these problems, the use of rubber with high elastic modulus and strong impact resistance to replace metal materials has been listed as a frontier topic in the scientific research field of high efficiency, energy saving and environmental protection in mechanical transmission systems. The rubber coupling transmits the torque thro...
