Abstract
The invention relates to a torque limiting anti-overload device which is suitable for the occasions needing torque limiting or overload protection in the mechanical equipment transmission process. Elastic force of a spring is adjusted through an adjustable mechanism composed of a screw, a spring II and a compression spring gasket, and the torque overload limit value is determined according to the magnitude of the elastic force; when a driving shaft rotates to the ultimate torque, a connecting sleeve compresses the spring I, and a transmission pin slides down to the end, away from an electromagnet, of a 90-degree long strip hole, so that the pressure of a steel ball clutch is lowered, and a driven shaft slips; and when the driving shaft stops rotating, the electromagnet attracts the transmission pin back to the original position.
Description
Technical field
Overload device is prevented the present invention relates to a kind of limited torque, it is adaptable to need to limit moment of torsion in plant equipment transmission process
Or need the occasion of overload protection.
Background technology
In plant equipment transmission, some machine work occasions need to install overload protection dress for the appearance for preventing accident
Put, overload device causes that power drive system and servo system are separated so as to play a protective role when a fault occurs, such as exist
The process of screwing bottle cap is accomplished by setting overload protection arrangement in microorganism culture flask sacking, so as to reach protection microorganism training
Support the purpose of bottle.Conventional overload device uses friction plate, causes precision inadequate and not wear-resisting, wastes time and energy, and influences efficiency.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of new limited torque overload protective device, and the overload device front end is
Adjustable mechanism is constituted by screw, spring II and pressing spring pad, than the moment of torsion needed for more accurate regulation, can be certainly after abrasion
Dynamic compensation, is conducive to long-term use, is particularly well-suited to require there is the workplace for limiting moment of torsion and preventing overload.
To solve problem above, the present invention uses technical scheme：A kind of limited torque overload protective device, it is characterised in that institute
State limited torque overload protective device including driven shaft, steel ball clutch, adapter sleeve, minitype electromagnet, spring I, screw, spring II,
Pressing spring pad, driving shaft, trundle, driving shaft are extend into adapter sleeve, and 90 degree of strip holes, trundle are provided with adapter sleeve
Driving shaft is set to be connected with adapter sleeve through 90 degree of strip holes, and right angle in 90 degree of strip holes is provided with minitype electromagnet, even
Female connector and driven shaft are connected by steel ball clutch, and driving shaft front end is provided with pressing spring pad, adapter sleeve and pressing spring pad
Between be provided with spring I, spring I is enclosed within driving shaft；3 screws are installed, 3 between screw and driving shaft on pressing spring pad
Two 120 degree of twenty percent angles, are provided with spring II between pressing spring pad and screw, spring II is enclosed within screw.
Brief description of the drawings
Fig. 1 prevents the structural representation of overload device for limited torque.

Specific embodiment
As shown in the figure, 1. 9. a kind of limited torque overload protective device, driving shaft pass through two 2. of steel ball clutch with driven shaft
End links together, driving shaft 9. on be provided with by screw 6., the adjustable mechanism that is 7. 8. constituted with pressing spring pad of spring II, pressure
5. 8. spring shim be provided with spring I between adapter sleeve 3. end face, adapter sleeve 3. on be provided with 90 degree of strip holes, and at 90 degree
4. the right angle of strip hole is provided with minitype electromagnet：During 3. 9. driving shaft extend into adapter sleeve, trundle is 10. through 90 degree of length
Bar hole makes driving shaft be 9. 3. connected with adapter sleeve, and 2. 3. adapter sleeve connect with steel ball clutch, steel ball clutch 2. another
1. one end is connected with driven shaft.
The course of work of the new limited torque overload protective device is, by by screw 6., spring II 7. with pressing spring pad
8. the adjustable mechanism for constituting adjusts the elastic force of spring, the limiting value of torque overload is determined by the size of elastic force, when actively
When 9. axle is rotated up to ultimate torque, adapter sleeve 3. will holddown spring I 5., and 10. trundle is slipped to the remote of 90 degree of strip holes
From one end of electromagnet, therefore cause the pressure that 2. steel ball clutch is gone up to reduce, realize that 1. driven shaft skids, when 9. driving shaft stops
During rotation, 4. trundle can be sucked back electromagnet original position.Beneficial effects of the present invention：
1) the limited torque device automatic performance in this patent is relatively good, and initial shape can be automatically reverted to after having worked once
State, being capable of continual work.
2) cost is cheap, and practicality is higher, installs and debugging is convenient, is easy to safeguard, easy to operate.
4) the technical problem to be solved in the present invention is to provide a kind of new limited torque overload protective device, and the overload device is used
Adjustable, required than the more accurate regulation moment of torsion being made up of spring, screw and pressing spring pad, can be automatic after abrasion
Compensation, is conducive to long-term use, is particularly well-suited to require there is the workplace for limiting moment of torsion and preventing overload.
5) steel ball clutch be conducive to extend overload device life-span, improve efficiency.
