Abstract
The invention belongs to the mechanical drive field, and more particularly relates to a method applied to bearing bending torque of a gear drive device. The method is characterized in that an elastic torque arm is connected between a frame (3) and a draw plate (13); the bending torque generated by the gear drive device is transmitted to an elastic rod of the elastic torque arm by the draw plate (13), the elastic rod is internally provided with a cylindrical helical compression spring (5) with adjustable amount of compression, the elasticity of the elastic rod is regulated by adjusting the amount of compression of the spring (5), the elastic rod is connected with the frame (3), and the bending torque is transmitted to the frame (3) by the elastic rod to buffer and absorb impact load. The method can relieve the acting force of the impact load on the gear drive, and improve the operation smoothness of the drive device.
Description
Technical field
The invention belongs to mechanical transmission fields, particularly a kind of method that is applied to bearing branch counter moment of gear assembly.
Background technique
In a kind of typical gear drive application, the output shaft of gear drive is a hollow shaft, this output shaft is set on the live axle of working machine, fetch by shrink disc, ringfeder or binding Operating torque is delivered on the live axle of working machine, gear drive is whole to be suspended on the live axle of working machine.Generally speaking, the branch counter moment of transmission device generation is delivered on the support by a rigidity toggle.Because what adopt is the rigidity toggle, impulsive load can produce vibration and impact to gear drive, thereby causes gear destruction, shortens the life-span of transmission device.
Summary of the invention
The purpose of this invention is to provide a kind of method of slowing down impulsive load, so that improved the smoothness of operation of transmission device to the bearing branch counter moment of gear assembly of gear transmission active force.
The object of the present invention is achieved like this, and the method for bearing branch counter moment of gear assembly is characterized in that: be connected the elastic torsion arm between support and arm-tie; The branch counter moment that gear drive produces is delivered on the elastic rod of elastic torsion arm by arm-tie, the adjustable cylindroid helicalcoil compression spring of decrement is installed in the elastic rod, by adjusting amount of spring compression, adjust the elasticity of elastic rod, elastic rod is connected with support, branch counter moment is delivered on the support by elastic rod, buffering and absorption impulsive load.
Described elastic torsion arm comprises block, spring, upper connecting rod, spacer, bolt, attaching nut, lower link, bearing pin, backing pin plate; Lower link is the hollow bar, one end has platform, the other end has through hole, and platform end clamping arm-tie up and down is fixedly connected by bearing pin, and the fixing head of bolt puts in the through hole and fixes by attaching nut and upper connecting rod port, socket spring on the bolt stock, spring is movably connected in the cavity of upper connecting rod by spacer and block clamping, and another close mouth end of upper connecting rod outwards has connecting sheet, connecting sheet is connected with support by bearing pin, and the backing pin plate is connected with support with bearing pin.
Advantage of the present invention is: be connected the elastic torsion arm between support 3 and arm-tie 13, the amount of spring compression of the adjustable elastic bar of elastic torsion arm can realize that this has just realized the adjustment of the elasticity size of elastic rod by the thickness of change spacer 7.The desired stand structure of adjustable elastic toggle is simple; avoided the lower margin or the flange of gear drive to connect; simultaneously; because this toggle can be adjusted the decrement of spring according to the actual load situation at scene; can realize the absorption and the buffering of impact load well, reach the purpose of protection transmission device.
