Abstract
The utility model relates to an elastic torque protection device, primarily used for connecting between two rotation shafts to avoid damage of the rotation shafts or equipment on the rotation shafts resulting from excessive speed or small speed of the rotation shafts. The elastic torque protection device comprises a left flange, a right flange, a screw cap, a steel rod and a shaft sleeve. The left end of the shaft sleeve is integrated with the left flange, the right end of the shaft sleeve is provided with a mounting seat, the diameter of the mounting seat is smaller than that of a sleeve body of the shaft sleeve, and the right flange is arranged round the mounting seat. Left flange holes on the left flange and right flange holes on the right flange are of the same quantity, and are arranged correspondingly one to one. One end of the steel rod is retained in the left flange holes, and the other end of the steel rod is fixed through the screw caps after passing through the right flange holes. The elastic torque protection device has the advantages of reasonable structural design, compact and simple structure, easy manufacture, convenient assembly and disassembly, good process and wide application.
Description
Technical field
The utility model relates to a kind of elastic torque protective gear, is mainly used in to be connected between two rotatingshafts, be used to prevent rotatingshaft because of rotating speed the excessive or too small device damage that is connected on rotatingshaft and the rotatingshaft of causing.
Background technique
Epoch in that machine building industry constantly develops in order to improve the machinery comprehensive performance, in the machinery manufacture process, need incorporate brand new concept, in the life-span how prolongation equipment uses, how safety in production are placed above the other things or the like.Safety in production has many types, but its main object is in process of production safety still, particularly in using machinery, because the mistake of data input, pressing the wrong button because of carelessness like thatly all can cause dangerous production and can cause burden to worker's body and mind safety.Safety protection device is the thing that urgently can not treat so pack in machinery, and this type of device needs working principle simple, and the cost cost is low, could make huge contribution for economic benefit and social benefit like this.After country had proposed " safety in production " this notion, protection device for installing can become the important component part of manufacturing machine equipment in machinery, also was a direction of mechanical industry development.
The model utility content
Technical problem to be solved in the utility model is to overcome existing above-mentioned shortcoming in the prior art, and the elastic torque protective gear that a kind of reasonable in design is provided, can plays a protective role to the equipment that rotatingshaft connects.
The technical scheme in the invention for solving the above technical problem is: a kind of elastic torque protective gear is characterized in that: comprise left flange, right flange, nut, rod iron and axle sleeve; The left end of axle sleeve and left flange hold together, and right-hand member forms the fitting seat of a diameter less than the body diameter, is set with right flange on the fitting seat; A left side on the flange left flange hole and the right flange hole quantity on the right flange equates and one by one over against; One end of rod iron is fixed in the left flange hole, and the other end was used fixed by nut after installing right flange hole.
Have the screw thread that cooperates with nut on the rod iron described in the utility model, have in the left flange hole with rod iron on the screw thread of screw-thread fit; Described rod iron threaded one end is fastened in the left flange hole, and the other end is threaded fixing with nut.
Left flange hole described in the utility model and right flange hole are 12, and described rod iron is 12, and described nut is 12.
The utility model compared with prior art has the following advantages and effect: 1, reasonable in design; 2, compactness is simple, making is easy, install and remove convenience, good manufacturability, of many uses.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment.
Embodiment:
Referring to Fig. 1～Fig. 6, the utility model embodiment comprises left flange 1, right flange 2, rod iron 3, axle sleeve 4 and nut 5.
Axle sleeve 4 is linked to be an integral body at left end and left flange 1, and right-hand member forms the fitting seat 41 of a diameter less than the body diameter, and the transition position of body and fitting seat 41 is a vertical plane 42.Right flange 2 is sleeved on the fitting seat 41 and by vertical plane 42 and blocks.
On left flange 1, have 12 left flange holes 11, on right flange 2, have 12 right flange holes 21.12 left flange holes 11 and 12 right flange holes 21 one by one over against, that is to say that each left flange hole 11 faces a corresponding with it right flange hole 21.Rod iron 3 is 12, has screw thread 31 on rod iron 3, and this screw thread 31 cooperates with nut 5.In the flange hole 11 of a left side and have a screw thread that cooperates with screw thread 31 on the rod iron 3.Rod iron 3 threaded one ends are fastened in the left flange hole 11, the other end installed with this left side flange hole 11 over against right flange hole 21 in the back tighten with nut 5 itself and right flange 2 fixed, like this, one end of 12 rod irons 3 is separately fixed in 12 left flange holes 11, the other end installed 12 right flange holes, 21 backs respectively and tightened fixingly with nut 5, and 12 rod irons 3 are parallel each other with axle sleeve 4.Rod iron 3 plays the effect of protection simultaneously of rotating of transmitting.Under the effect of nut 5 and vertical plane 42, right flange 2 is fixed.
On left flange 1, be connected with slewing gears such as rotatingshaft, on right flange 2, be connected with slewing gears such as another rotatingshaft.The utility model plays the effect of protection simultaneously of rotating of transmitting.When left flange 1 rotates, can drive right flange 2 by rod iron 3 and rotate, axle sleeve 4 rotates together simultaneously.When meeting accident, such as being connected that rotatingshaft rotating speed on left flange 1 or the right flange 2 reduces owing to mechanical disorder or when increasing to beyond the safe speed of rotation, because left flange 1 can be inequality with right flange 2 rotating speeds, thereby can produce very big moment of torsion, when moment of torsion exceeds the tolerance range of rod iron 3, rod iron 3 fractures, the rotation transmission between left flange 1 and the right flange 2 stops, and machine decommissions automatically.
In addition, need to prove, the specific embodiment described in this specification, its zero, the shape of parts, institute's title of being named etc. can be different.Allly conceive equivalence or the simple change that described structure, feature and principle are done, be included in the protection domain of the utility model patent according to the utility model patent.
