Abstract
The utility model relates to a torque limiter for generating torque through friction force. The torque limiter comprises an outer shell (1), an upper cover (4) and an axis (5), wherein the axis (5) is arranged in the center of the interior of the outer shell (1), the upper cover (4) is installed between one side of the outer shell (1) and the axis (5), and a spring (2) is installed between the outer side of the axis (5) and the inner side of the outer shell (1) in a connected mode. The torque limiter is simple in structure, few in parts, convenient to assemble and low in cost.
Description
Technical field
The utility model relates to torque limiter manufacturing technology field, particularly relates to a kind of torque limiter that utilizes frictional force to produce moment of torsion.
Background technique
Torque force limiting device (also is torque limiter; safety coupling, safety clutch); be a kind of parts that connect active machine and working machine; major function is overload protection; torque force limiting device is when overload or mechanical failure and when causing required torque to surpass setting value; it recovers after moment of torsion disappears to connect with the torsion of the form limiting drive train system institute transmission of skidding voluntarily.So just prevent mechanical failure, avoided expensive shutdown loss.
The principle of employing torque limiter can be designed to the industrial devices of not same-action of all kinds at present, but most devices all are complex structures, and part is many, and manufacturing process is many, and manufacture cost is higher.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of torque limiter that utilizes frictional force to produce moment of torsion, and simple in structure, part is few, and is easy to assembly, and cost is low.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of torque limiter that utilizes frictional force to produce moment of torsion is provided, comprise shell, loam cake and axle center, the inside center of described shell is furnished with the axle center, between one side of described shell and the axle center loam cake is installed, is connected and installed with spring between the inboard of the outside, described axle center and shell.
Described spring is fixedlyed connected with the axle center, closely contacts with shell.
Between one side of described spring and the loam cake rubber sheet gasket is installed.
Beneficial effect
The utility model relates to a kind of torque limiter that utilizes frictional force to produce moment of torsion, simple in structure, utilize the debt friction of spring to produce moment of torsion, torque limiter axle center and shell when its suffered outside torsion is no more than particular value can not rotated, easily manufactured, cost is low.
Description of drawings
Fig. 1 is the structural representation that partly cuts open of the present utility model.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiments only are used for explanation the utility model and are not used in the scope of the present utility model that limits.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As shown in Figure 1, mode of execution of the present utility model relates to a kind of torque limiter that utilizes frictional force to produce moment of torsion, comprise shell 1, loam cake 4 and axle center 5, the inside center of described shell 1 is furnished with axle center 5, between one side of described shell 1 and the axle center 5 loam cake 4 is installed, is connected and installed with spring 2 between the inboard of 5 outsides, described axle center and shell 1.
Described spring 2 is fixedlyed connected with axle center 5, closely contacts with shell 1, between a side of described spring 2 and the loam cake 4 rubber sheet gasket 3 is installed.
Utilize the torsion of the frictional force generation of spring, torque limiter axle center 5 when its suffered outside torsion is no more than particular value can not rotated with shell 1.
