Abstract
The utility model pertains to the field of mechanical transmission and particularly relates to an adjustable elastic torque arm which is characterized in that an elastic torque arm is connected between a frame (3) and a draw plate (13); support reaction torque generated by a gear transmission device is transmitted to an elastic rod of the elastic torque arm by the draw plate (13); a cylindrical helical compression spring (5) with adjustable compression is installed in the elastic rod; the elasticity of the elastic rod is adjusted by adjusting the compression of the spring (5); the elastic rod is connected with the frame (3); and the support reaction torque is transmitted to the frame (3) by the elastic rod to buffer and adsorb the impact load. The adjustable elastic torque arm can mitigate the acting force of the impact load to the gear transmission and improve the running smoothness of the transmission device.
Description
Technical field
The utility model belongs to mechanical transmission fields, particularly a kind of adjustable elastic toggle that is applied to.
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 utility model provides a kind of adjustable elastic toggle that slows down impulsive load to the gear transmission active force, so that improved the smoothness of operation of transmission device.
The purpose of this utility model is to realize like this, the adjustable elastic toggle, the elastic torsion arm is connected between support and arm-tie, and it is characterized in that: the 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, 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 socket spring on the bolt stock by coupling nut and upper connecting rod port, spring is movably connected in the cavity of upper connecting rod by spacer and block clamping, another close mouth end of upper connecting rod outwards has connecting sheet, and connecting sheet is connected with support by bearing pin, and the backing pin plate is connected with support with bearing pin.
The utility model has the advantages that: 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.
Description of drawings
The utility model is described in further detail below in conjunction with embodiment's accompanying drawing.
Fig. 1 is the utility model embodiment sectional structure schematic representation;
Fig. 2 is the utility model example structure schematic representation.
Among the figure: 1, backing pin plate; 2, bearing pin; 3, support; 4, block; 5, spring; 6, upper connecting rod; 7, spacer; 8, bolt; 9, hold out against screw; 10, attaching nut; 11, lower link; 12, bearing pin; 13, arm-tie; 14, backing pin plate.
Embodiment
As shown in Figure 1 and Figure 2, the elastic torsion arm comprises block 4, spring 5, upper connecting rod 6, spacer 7, bolt 8, attaching nut 10, lower link 11, bearing pin 12, backing pin plate 14; Lower link 11 is the hollow bar, one end has platform, the other end has through hole, platform end clamping arm-tie 13 up and down is fixedly connected by bearing pin 12, the fixing head of bolt 8 puts in the through hole and fixes with upper connecting rod 6 ports by attaching nut 10, hold out against screw 9 on attaching nut's 10 exterior edge face upper connecting rods 6, socket spring 5 on bolt 8 stocks, spring 5 is movably connected in the cavity of upper connecting rod 6 by spacer 7 and block 4 clampings, the amount of spring compression of adjustable elastic bar can realize that this has just realized the adjustment of the elasticity size of elastic rod by the thickness of change spacer 7.In actual applications, can adjust the amount of spring compression in the elastic rod, reach the optimum state of slowing down the impact absorption vibration according to the size and the stationarity of work loads.Upper connecting rod 6 another close mouth ends outwards have connecting sheet, and connecting sheet is connected with support 3 by bearing pin 2, and backing pin plate 1 is connected with support 3 with bearing pin 2.Arm-tie 13 is connected by the housing of flange and gear drive, the branch counter moment of gear drive is delivered on the arm-tie 13 by housing, arm-tie 13 is connected with lower link 11 by bearing pin 12, branch counter moment is delivered to lower link 11 thus, be delivered on the spring 5 by bolt 8 again, the load of spring 5 is delivered to upper connecting rod 6 by attaching nut 10, and upper connecting rod 6 is connected with support 3 by bearing pin 2, and impulsive load is delivered to fixedly on the support 3 thus.
