Description
Technical field
The utility model relates to the connected element between machine industry axis and the axle, particularly a kind of bullet, stiff assembly coupling.
Background technique
At machine industry, axle with spool, equipment is connected by coupling with equipment is common thing, coupling can be divided into rigid coupling and elasticity (flexible) coupling.
Rigid coupling or claim permanent coupling, though this coupling does not have compensation performance, have simple in structure, easy to manufacture, need not safeguard, characteristics such as cost is low and its using scope should be arranged.Elastic coupling flexible coupling contains the parts that can produce big resiliently deformable, also has buffering and damping effect except that compensation performance is arranged, but on the ability of transmitting torque, because of the intensity that is subjected to elastic element limits, general not as good as rigid coupling.
Produce making " bullet, stiff assembly coupling " idea, is a workshop overhead traveling crane that derives from our factory, and " the band brake wheel elastic dowel pin shaft coupling " of the reduction gear box on it often needs personnel's maintenance of ascending a height, and frequency of maintenance is higher, and it is relatively poor to keep in repair environment.
" band brake wheel elastic dowel pin shaft coupling " is a kind of standard piece, and standard No. is GB4323-84.This kind coupling in use has following problem: the frequent corrupted of (1) flexible rubber ring; (2) oval appears in the attachment hole of flexible rubber ring; (3) connecting pin often becomes flexible; Distortion appears in the cone shape hole that (4) is connected with pin.When above problem occurred simultaneously, this coupling just must be changed.
The reason that above problem occurs is very simple: " band brake wheel elastic dowel pin shaft coupling " is a kind of coupling of strap brake hub exactly, when overhead traveling crane lift heavy thing, often rely on brake to make the skyborne a certain position of Chong Wu Xuan, bump and the extruding that can cause flexible rubber ring and attachment hole this moment also can cause flexible rubber ring and bump that is connected pin and extruding.This bump and extruding make the external diameter surface serious wear of flexible rubber ring, and outside dimension diminishes gradually; Inside diameter surface is serious wear too, and it is big that interior hole dimension becomes gradually.Flexible rubber ring will lose normal work functions like this, will come off when serious.The connection pin of coupling is six generally speaking, after flexible rubber ring corrupted that certain connecting pin nails on comes off, will make the few power transmission point of coupling, stressed will increase of flexible rubber ring of nailing on of Sheng Xia five connecting pins so, the speed of corrupted will be accelerated, if untimely replacing flexible rubber ring, final result is exactly that the flexible rubber ring that nails on of all six connecting pins all comes off, if can not in time find again, the rigid impact of pin and coupling body will occur connecting, in the course of time, connect pin and occur crooked, distortion occurs with the taper hole that is connected the pin connection, connect pin and occur becoming flexible.Finally cause coupling normally not use.Various coupling up till now mostly are the product by standard production greatly, or are rigid coupling, or are elastic coupling flexible coupling.
Summary of the invention
At the problem that exists in the above-mentioned technology, the purpose of this utility model provides a kind of bullet, stiff assembly coupling, increases work efficiency the working life that is beneficial to improve coupling, reduces cost.
For achieving the above object, technical solution of the present utility model provides a kind of bullet, the stiff assembly coupling, wherein: this coupling includes Brake drum, shaft coupling, connect platen, spacer shell, connect pin, flexible rubber ring, clamping bolt, equally spaced a plurality of through holes and the tapped hole of being provided with on the described Brake drum, spacer shell and flexible rubber ring are installed in the through hole on the described Brake drum, on described shaft coupling, be provided with a plurality of through holes, the central position of these through holes is corresponding with a plurality of through holes on the Brake drum, pass through hole on the shaft coupling and the flexible rubber ring in the Brake drum through hole successively by connecting pin, one end of described connection pin by nut check in shaft coupling one side, it is fixing that the other end of described connection pin and the taper hole that is connected platen are seated, and described clamping bolt passes the through hole that connects platen and is screwed in the tapped hole on the Brake drum.
Effect of the present utility model is to use the use of this " bullet, stiff assembly coupling ", can prolong the working life of coupling; Reduce and change flexible rubber ring and maintenance times; Easy to maintenance.Particularly use, more show its superiority in the place of inconvenience maintenance.

Embodiment
In conjunction with the accompanying drawings bullet of the present utility model, stiff assembly coupler structure are illustrated.
1). the flexible rubber ring of former coupling is directly to contact with its attachment hole, now changes into setting up a spacer shell between the two, and wear-resisting for guaranteeing, the spacer shell material is selected the 65Mn steel for use.As owing to make spacer shell wearing and tearing occur for a long time, also only need its replacing is got final product, the replacing of coupling integral body can not appear.
2). improve stressing conditions: former connection pin is that cantilever type, single strong point are stressed, and it is stressed now to change dual-gripper point into.Like this, can improve the taper hole stressing conditions that connects pin, make taper hole not yielding, thereby make coupling keep normal for a long time the use.
3). the structure of former connection pin is: an end is the cone form, and the other end is a flange forms.Now change two ends into and be the cone form.
4). for realizing being rigidly connected, need set up one and connect platen.Connecting the through hole of offering taper hole and connecting bolt on the platen, taper hole and pin cone match, and through hole is used to be connected and fixed bolt.
Bullet of the present utility model, the stiff assembly coupling, this coupling includes Brake drum 1, shaft coupling 3, connect platen 4, spacer shell 6, connect pin 2, flexible rubber ring 5, clamping bolt 7, equally spaced a plurality of through holes and the tapped hole of being provided with on the described Brake drum 1, spacer shell 6 and flexible rubber ring 5 are installed in the through hole on the described Brake drum 1, on described shaft coupling 3, be provided with a plurality of through holes, the central position of these through holes is corresponding with a plurality of through holes on the Brake drum 1, pass through hole on the shaft coupling 3 and the flexible rubber ring 5 in Brake drum 1 through hole successively by connecting pin 2, one end of described connection pin 2 by nut check in shaft coupling 3 one sides, it is fixing that the other end of described connection pin 2 and the taper hole that is connected platen 4 are seated, and described clamping bolt 7 passes the through hole that connects platen 4 and is screwed in the tapped hole on the Brake drum 1.
Have a plurality of through holes on the described shaft coupling 3 and be taper hole, tapering is 1: 10.Described connection pin 2 is a cone shape, and tapering is 1: 10, and wherein an end is provided with screw thread.Described flexible rubber ring 5 is ring apron or helical cushion rubber.
