Description
Technical field：
A kind of torque force limiting device is the utility model is related to, especially a kind of friction-type torque force limiting device.
Background technology：
Overload protection is used in many plant equipment now, when driven load is unstable, when impulsive force is larger, or is set
When being broken down during received shipment row, it is desirable to have overload protection arrangement in the transmission system.Friction-type torque force limiting device is usually used in
Between powerdriven active and passive side, when in operation overload fault occurs for equipment, it is possible to in transmission system
Motor, reductor, gear etc. carry out overload protection, for larger jumbo or expensive equipment, the limitation of friction-type torsion
Device can also safety transmission moment of torsion, when equipment, which is run, to break down, affected at first is it, reparation to it installation
It is it is required that simple and easy.At present, existing friction-type torque force limiting device will be sequentially adjusted in when amount of spring compression is adjusted
Six hex nuts, during this six nuts are adjusted, it is easy to error occur, prevent amount of spring compression from keeping height
Uniformity.
Utility model content：
The utility model provides a kind of friction-type torque force limiting device, and it is reasonable in design, by adjusting single nut
Position adjust spring decrement, avoid and occur error during adjustment, ensure that amount of spring compression can keep one
Cause property, solves problems of the prior art.
The utility model is that technical scheme is used by solving above-mentioned technical problem：
A kind of friction-type torque force limiting device, including be set in the axle sleeve on the outside of horizontally disposed driven shaft, axle sleeve with it is driven
It is connected between axle by key, back-up ring is provided with one end of axle sleeve, a bushing is provided with the outer sheath of axle sleeve, in the outer sheath of bushing
Provided with friction member, friction member is fixed on support member by hexagon socket cap head screw, is provided with and is rubbed between friction member and back-up ring
Pad, friction member, friction plate and back-up ring are abutted against, and pressurization disk is also arranged with the outside of axle sleeve, and the pressurization disk is located remotely from
The side of back-up ring, friction plate also is provided between pressurization disk and friction member, is abutted against between pressurization disk, friction plate and friction member,

Embodiment：
For the technical characterstic for illustrating this programme can be understood, below by embodiment, and its accompanying drawing is combined, to this reality
It is described in detail with new.
As shown in fig. 1, a kind of friction-type torque force limiting device, including it is set in the axle sleeve on the outside of horizontally disposed driven shaft
1, it is connected between axle sleeve 1 and driven shaft by key, back-up ring 2 is provided with one end of axle sleeve 1, a lining is provided with the outer sheath of axle sleeve 1
Set 3, friction member 4 is provided with the outer sheath of bushing 3, and friction member 4 is fixed on support member 5 by hexagon socket cap head screw 6,
Friction plate 7 is provided between friction member 4 and back-up ring 2, friction member 4, friction plate 7 and back-up ring 2 are abutted against, also covered in the outside of axle sleeve 1
Provided with pressurization disk 8, the pressurization disk 8 is located remotely from the side of back-up ring 2, and friction plate also is provided between pressurization disk 8 and friction member 4
7, abut against between pressurization disk 8, friction plate 7 and friction member 4, covered successively on axle sleeve 1 away from the side of friction plate 7 in pressurization disk 8
Provided with disc spring 9, drag washer 10 and round nut 11, the pressurization disk 8, disc spring 9, drag washer 10 and round nut 11 offset successively
Connect.
Carrying out, in use, when needing the frictional force to torque force limiting device to be adjusted, adjusting the position of round nut 11,
When round nut 11 moves towards disc spring side, disc spring 9 is compressed, so that disc spring 9 compresses pressurization disk 8, pressurization disk 8 is compressed and rubbed
Pad 7 so that between friction member 4 and the friction plate of both sides 7, the frictional force increase between two friction plates 7 and axle sleeve 1.
Using friction-type torque force limiting device of the present utility model, compressed by adjusting the position of single nut to adjust spring
Amount, avoids and occurs error during adjustment, ensure that amount of spring compression being capable of being consistent property.
Above-mentioned embodiment cannot function as the limitation to scope of protection of the utility model, for the skill of the art
For art personnel, any alternate modification or conversion made to the utility model embodiment all fall within guarantor of the present utility model
In the range of shield.
Part is not described in detail for the utility model, is the known technology of those skilled in the art of the present technique.
