Description
Technical field
The utility model relates to a kind of elastic connecting device, is mainly used in, in machine driven system, belonging to technical field of mechanical transmission.
Background technique
In mechanical transmission, speed reducer Main Function is the moment of torsion and rotating speed that the moment of torsion that exported by prime mover (motor, steam turbine, oil hydraulic motor etc.) and rotating speed convert that applicable working machine requires to, but in actual applications, speed reducer often bears again extra radial and axial load.Such as, when speed reducer is connected with working machine by belt, the output shaft of speed reducer will bear the radial load that belt tension causes.Also having when producing axial float in working machine work, also will produce extra thrust load to speed reducer.These extra radial and axial load can cause harmful effect to the bearing of speed reducer and gear, and its life-span is shortened dramatically.
Summary of the invention
The purpose of this utility model is to provide a kind of connection set, and this device, while connection speed reducer and working machine, can shield axis and the radial load of working machine generation, make speed reducer be in more reasonably using state.
For achieving the above object, the technical solution of the utility model is to provide a kind of elastic connecting device, comprise roller bearing, connecting sleeve, expansion set, spring sheet, outer press ring, inner pressure ring and connecting bolt, spring sheet adopts high-strength spring steel plate to process, and the output shaft of speed reducer is connected with upper the coiling of working machine by elastic connecting device.
Speed reducer is fixed on matrix, and roller bearing is arranged in the bearing support of matrix, and the upper dish of working machine is arranged in the endoporus of roller bearing, is radially oriented.Leave the gap of 1mm between the output shaft of speed reducer and the endoporus of upper dish, the radial vibration of working machine is delivered on matrix by roller bearing, and can not be delivered on the output shaft of speed reducer.Connecting sleeve is connected with the output shaft of speed reducer by expansion set, leaves 3 ~ 5mm gap between the bottom surface of expansion set and connecting sleeve and the upper dish of working machine.One end of spring sheet is fixed on connecting sleeve by inner pressure ring and connecting bolt, the other end by outer press ring and connecting bolt be fixed on working machine on coil.When working machine produces axial float, spring sheet plays the effect of buffering, fully absorbs axial float, thus the thrust load that the output shaft substantially reducing speed reducer bears.
Use of the present utility model overcomes the deficiency in existing machinery transmission system in connection set, can effectively reduce the axis because load play produces speed reducer and radial load, the working life of speed reducer is significantly extended.

embodiment
For making the utility model become apparent, hereby with a preferred embodiment, and accompanying drawing is coordinated to be described in detail below:
Composition graphs 1, Fig. 2, Fig. 3 and Fig. 8, during machine driven system use elastic connecting device 10, first fixed over substrate 12 by speed reducer 13, roller bearing 7 is arranged in the bearing support of matrix 12, the upper dish of working machine 11 is arranged in the endoporus of roller bearing 7, is radially oriented; Leave the gap of 1mm between the output shaft of speed reducer 13 and the upper dish endoporus of working machine 11, the radial vibration of working machine 11 is delivered on matrix 12 by roller bearing 7, and can not be delivered on the output shaft of speed reducer 13; The output shaft of connecting sleeve 5 with speed reducer 13 is connected by expansion set 6, leaves 3 ~ 5mm gap between the bottom surface of expansion set 6 and connecting sleeve 5 and the upper dish of working machine 11; One end of spring sheet 3 is fixed on connecting sleeve 5 by inner pressure ring 4 and connecting bolt 2, the other end by outer press ring 1 and connecting bolt 2 be fixed on working machine 11 on coil, the spring sheet 3 of some arranges at circumference uniform distribution, and spring sheet center line 8 is tangent with connecting sleeve center line 9, use 3 ~ 5 layers of spring sheet 3 to be superimposed as spring plate group to use, the spring sheet 3 of every layer is separated by inner pressure ring 4 and outer press ring 1, does not directly contact; When working machine 11 produces axial float, spring sheet 3 plays the effect of buffering, fully absorbs axial float, thus the thrust load that the output shaft substantially reducing speed reducer 13 bears.
Claims (3)
