Abstract
The utility model relates to a novel limit moment of torsion antioverloading device, driving shaft pass through the both ends of the coaxial setting of driven shaft at the adapter sleeve, be equipped with threaded connection's adjustable nut on the driving shaft, be equipped with the spring between adjustable nut and the adapter sleeve terminal surface, be equipped with 90 degrees rectangular holes on the adapter sleeve, trundle I passes 90 degrees rectangular kong houyu driving shafts and connects, corresponding driven axle head at the adapter sleeve and being equipped with step circular arc transition face, be equipped with trundle II on the low surface of step circular arc transition face, trundle II is connected with the driven shaft. This overload device adopts spring and nut adjustable, the required moment of torsion of regulation of comparable accuracy, but automatic compensation can use for a long time after the wearing and tearing, and the specially adapted requires to have limited moment of torsion and prevent overstrain work occasion.
Description
Technical field
The utility model relates to a kind of novel limited torque overload protective device, for needing the occasion limiting moment of torsion or need overload protection in machinery transmission, belonging to mechanical transmission and manufacturing field.
Background technique
In machinery transmission, some mechanical transmission workplace is that the appearance of Accident prevention needs to install overload protection arrangement, overload device makes power transmission system and throws off from transmission system thus play a protective role when a fault occurs, some mechanical transmission needs to limit Operating torque, as: the line belt had is operationally owing to will arrange overload device when goods overloads and when having goods to clamp, torque wrench is limit certain moment of torsion output to be also provided with overload device, overload device in the past adopts friction plate, precision is inadequate and not wear-resisting, need often to regulate, waste time and energy, affect utilization efficiency.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of novel limited torque overload protective device, this overload device adopt spring and nut adjustable, moment of torsion needed for comparable more accurate adjustment, after wearing and tearing can auto-compensation can Long-Time Service, be specially adapted to require to have the workplace limiting moment of torsion and prevent from transshipping.
For overcoming the above problems, concrete technological scheme of the present utility model is as follows: a kind of novel limited torque overload protective device, and driving shaft is coaxially arranged on the two ends of connecting sleeve by driven shaft; Driving shaft is provided with the adjustable nut be threaded, between adjustable nut and connecting sleeve end face, is provided with spring; Connecting sleeve is provided with 90 degree of strip holes, and driving pin I is connected with driving shaft through after 90 degree of strip holes; Be provided with step arc-shaped transitional surface at the corresponding driven axle head of connecting sleeve, be provided with driving pin II on the low surface of step arc-shaped transitional surface, driving pin II is connected with driven shaft.
The excircle of described adjustable nut is provided with Cock screw, and Cock screw withstands on the outer surface of driving shaft through after adjustable nut.
This novel limited torque overload protective device adopts on connecting sleeve and is shaped with 90 degree of strip holes; connecting sleeve and driving shaft are connected with spring, and when driven shaft torque overload, driven shaft starts to skid, thus Accident prevention is bionical; or when reaching the moment of torsion of regulation; driven shaft skids and stops operating, can auto-compensation owing to be provided with after spring wear, feature that can be non-maintaining for a long time; durable in use; structure is simple, low cost of manufacture, and being specially adapted to needs limit moment of torsion or need the mechanically operated workplace of overload protection.
Accompanying drawing explanation
Fig. 1 is the structural representation of novel limited torque overload protective device.
Embodiment
As shown in Figure 1, a kind of novel limited torque overload protective device, driving shaft 1 is coaxially arranged on the two ends of connecting sleeve 6 by driven shaft 8; Driving shaft 1 is provided with the adjustable nut 3 be threaded, between adjustable nut 3 and connecting sleeve 6 end face, is provided with spring 4; Connecting sleeve 6 is provided with 90 degree of strip holes, and driving pin I 5 is connected with driving shaft 1 through after 90 degree of strip holes; Be provided with step arc-shaped transitional surface at the corresponding driven axle head of connecting sleeve 6, be provided with driving pin II 7 on the low surface of step arc-shaped transitional surface, driving pin II 7 is connected with driven shaft.
The excircle of described adjustable nut 3 is provided with Cock screw 2, and Cock screw 2 withstands on the outer surface of driving shaft 1 through after adjustable nut 3.
The working procedure of this novel limited torque overload protective device is, carried out the elastic force of Regulation spring by adjustable nut 3, decided the limiting value of torque overload by the size of elastic force, then by Cock screw 2, adjustable nut 3 is fixed, prevent in the process of active rotation, adjustable nut 3 loosens.When driving shaft rotate reach capacity moment of torsion time, connecting sleeve will holddown spring 4, and driving pin I 5 is slipped to another angle of 90 degree of strip holes, therefore causes driving pin II 7 to depart from the step arc-shaped transitional surface of connecting sleeve 6, realizes driven shaft and skids.
Claims (2)
