Abstract
The utility model provides a torsion limiter. When a driving end is clamped, the torsion limiter is capable of avoiding damage caused by overloading to a motor and capable of preventing accidents. The torsion limiter comprises a driving wheel and a driven wheel. The driving wheel is connected with the driving end and the driven wheel is sleeved on the driving wheel through a lining. The torsion limiter is characterized in that sphere grooves are evenly formed in one side of the driven wheel and screw holes which match with the sphere grooves which are formed in the driven wheel are evenly formed in the driving wheel. Adjusting screws and adjusting springs penetrate through the screw holes and press ball head lifting pins into the grooves which are formed in the driven wheel.
Description
Technical field
The utility model relates to the limiter technical field, is specially a kind of torque force limiting device.
Background technique
In the occasion that is driven by motor, when driven end breaks down when being stuck, its load meeting exceeds a certain limit value, and is very easily damaged at this situation equipment, need to stop motor at once, burns to avoid motor overload, causes the accident.
Summary of the invention
For the defects of prior art, the utility model is carried and has been encircleed a kind of torque force limiting device, and when drive end was stuck, it can avoid the motor overload damage, and Accident prevention occurs.
The technical solution of the utility model is: it comprises driving wheel and driven wheel, described driving wheel is connected with drive end, described driven wheel is enclosed within on the driving wheel by lining, it is characterized in that: uniform spherical groove on the side of described driven wheel, be evenly distributed with on the described driving wheel with described driven wheel on tapped hole corresponding to spherical groove size, adjust screw and adjust spring by adjusting tapped hole, the bulb ejector pin is pressed in the groove of described driven wheel.
It is further characterized in that: be drilled with groove on the described bulb ejector pin; Corresponding described groove location place is drilled with the locking screw thread hole on the driving wheel, and lock screw and locking spring be by described locking screw thread hole, and stop pin is pressed into groove on the described bulb ejector pin; Described lining is nylon lining.
After adopting design of the present utility model, when the drive end driven, the cooperation of the bulb ejector pin by driving wheel and the groove of driven wheel, transfer motion power is to the moved end.When be obstructed in the moved end, the groove of bulb ejector pin and driven wheel produces relative movement, and groove retreats the extruding of bulb ejector pin, until disengage fully.Simultaneously along with the retreating of bulb ejector pin, the groove of bulb ejector pin falls back on the below of stop pin, and stop pin falls into groove, blocks the bulb ejector pin, prevents that ejector pin from being gone out again by spring, guarantees that the disengaged position of driving wheel and driven wheel is stable.Turn on the locking Spring screws, elongate stop pin, can finish and reset.Such design has effectively prevented from having played protective action because overload causes equipment to equipment, has improved device security.
Description of drawings
Fig. 1 is the schematic representation of the utility model normal state.
Embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
See Fig. 1, the utility model comprises driving wheel 1 and driven wheel 2, driving wheel 1 is connected with drive end 3, driven wheel 2 is sleeved on the driving wheel 1 by nylon lining 4, uniform spherical groove 5 on one side of driven wheel 1, be evenly distributed with on the driving wheel 1 with driven wheel on adjustment tapped holes 6 corresponding to spherical groove 5 size, adjust screw 7 and adjust spring 8 by adjusting tapped hole 6, bulb ejector pin 9 is pressed in the groove 10 of driven wheel.Be drilled with latch recess 11 on the bulb ejector pin 9; Corresponding described groove location place on the driving wheel 1 is drilled with big or small corresponding locking screw thread hole 12, and lock screw 13 and locking spring 14 be by described locking screw thread hole 12, and stop pin 15 is pressed into latch recess 11 on the described bulb ejector pin.
After adopting design of the present utility model, when drive end 3 driven, the cooperation of the bulb ejector pin 9 by driving wheel and the groove 5 of driven wheel, transfer motion power is not to moved end (providing among the figure).When moved end (not providing among the figure) when being obstructed, bulb ejector pin 9 produces relative movement with the groove 5 of driven wheel, and groove 5 retreats 9 extruding of bulb ejector pin, until disengage fully.While retreating along with bulb ejector pin 9, the latch recess 11 of bulb ejector pin falls back on the below of stop pin 15, and stop pin 15 falls into latch recess 11, blocks bulb ejector pin 9, prevent that bulb ejector pin 9 is adjusted spring 8 and again goes out, guarantee that driving wheel 1 and driven wheel 2 disengaged positions are stable.After this can overhaul equipment after cutting off the electricity supply, after plant maintenance finishes, only need turn on locking Spring screws 14, elongate stop pin 12, can finish and reset.Such design has effectively prevented from having played protective action because overload causes equipment to equipment, has improved device security.
Claims (3)
