The utility model discloses a torsion coupler, which is used for connecting a driving shaft and a driven shaft and comprises two chain wheels, a casing pipe, a chain, friction plates, a pressing plate, a spring and a guide plate. a first chain wheel is sleeved on the driving shaft, the casing pipe is sleeved on the driven shaft, the first chain wheel and the casing pipe are connected through the chain, the two friction plates are arranged on the casing pipe, a second chain wheel is arranged between the two friction plates, one side of the pressing plate is connected with a friction plate away from the second chain wheel, and the other side of the pressing plate is connected with the guide plate through the spring. The torsion coupler has the advantages of being compact in structure, simple, reliable in work and the like, delivered torque can be adjusted in a certain range, and an overload protecting function is achieved.
Description
Technical field
The utility model relates to a kind of coupling, relates in particular to a kind of torsion coupling.
Background technique
Coupling makes its barycenter or principal inertia axis add shaft axis with it for various reasons and does not overlap; To produce the phenomenon of uneven centrifugal inertia force, centrifugal inertia idol power and dynamic deflection (vibration shape) in the running; This energy imbalance must cause the vibration of axle system, thus shadow error, axle stand under load and the distortion that produces, pedestal distortion, bearing wear, temperature variation (proper functioning and working life that heat expansion, shrinkage ring machine.
Diaxon that coupling joins is owing to foozle, installation), the multiple factors such as relative movement between the parts produce relative displacement.Generally speaking, the diaxon relative displacement is difficult to avoid, but the axle under the different working condition is the direction of displacement that transmission produces, promptly axially (x), radially (y), angle (a) and displacement amount is big or small different.Application area is restricted, so consumption seldom.
Summary of the invention
The purpose of the utility model just is to provide in order to address the above problem a kind of torsion coupling with compact structure, simple and reliable operation.
The utility model is realized above-mentioned purpose through following technological scheme:
The utility model is used to connect driving shaft and driven shaft, comprises sprocket wheel, sleeve, chain, friction plate, pressing plate, spring and guide plate, and said sprocket wheel is two; Said first sprocket wheel is socketed on the said driving shaft; Said jacket casing is connected with said chain between said first sprocket wheel and the said sleeve on said driven shaft, and said friction plate is two; Be arranged on the said sleeve; Said second sprocket wheel is arranged between said two friction plates, and a side of said pressing plate is connected with said friction plate away from said second sprocket wheel, is connected through said spring between the opposite side of said pressing plate and the said guide plate.
Particularly, said spring is a belleville spring.
Further, on the said guide plate adjusting screw is installed, on the said adjusting screw adjusting nut is installed.
Further, said friction plate is an asbestos-free friction sheet.
The beneficial effect of the utility model is:
The utlity model has advantages such as compact structure, simple and reliable operation, overload protection function can arbitrarily be adjusted, had to torque transmitted within the specific limits.
Description of drawings
Fig. 1 is the partial sectional view of the utility model;
Among the figure: 1-the first sprocket wheel, 2-sleeve, 3-chain, 4-asbestos-free friction sheet, 5-pressing plate, 6-belleville spring, 7-adjusting screw, 8-adjusting nut, 9-guide plate, 10-the second sprocket wheel, 11-driving shaft, 12-driven shaft.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1; The utility model comprises that first sprocket wheel 1, second sprocket wheel 10, sleeve 2, chain 3, asbestos-free friction sheet 4, pressing plate 5, belleville spring 6, adjusting screw 7, adjusting nut 8 and guide plate 9, the first sprocket wheels 1 are socketed on the driving shaft 11, and sleeve 2 is enclosed within on the driven shaft 12; Be connected with chain 3 between first sprocket wheel 1 and the sleeve 2; Asbestos-free friction sheet 4 is two, is arranged on the sleeve 2, and second sprocket wheel 10 is arranged between two asbestos-free friction sheets 4; One side of pressing plate 5 is connected with asbestos-free friction sheet 4 away from second sprocket wheel 10, is connected through belleville spring 6 between the opposite side of pressing plate 5 and the guide plate 9.Adjusting screw 7 is installed on the guide plate 9, install adjustment nut 8 on the adjusting screw 7.
Shown in Fig. 1; Through regulating adjusting screw 7 and adjusting nut 8, the pressing plate 5 and the gap of adjusting nut 8 are met the requirements, when operation torque during less than the torque set; The friction torque that second sprocket wheel, 10 bi-side produce is greater than operation torque; Through the friction torque between sleeve 2, pressing plate 5 and second sprocket wheel 10, by double strand chain 3, transmission of power on first sprocket wheel 1 and driving shaft 11.
In conjunction with Fig. 2, the process of the utility model work is following:
1, requires adjustment adjusting screw 7 according to equipment work, the pressing plate 5 and the gap of adjusting nut 8 are met the requirements;
2, when operation torque during less than the torque set; The friction torque that second sprocket wheel, 10 bi-side produce is greater than operation torque; Driving shaft 11 is through the friction torque between sleeve 2, pressing plate 5 and second sprocket wheel 10, by double strand chain 3, transmission of power on first sprocket wheel 1 and driving shaft 11;
3, when operation torque during less than the torque set; Can produce between second sprocket wheel 10 and the asbestos-free friction sheet 4 and skid relatively; Sleeve 2 idle running that drive motor is connected can't drive first sprocket wheel 1 and second sprocket wheel 10, thereby cut off the motion between motor and working machine.
