Abstract
The utility model relates to the technical field of mechanical transmission, in particular to a coupling. In order to solve the wear problem of the rigid coupling during the high speed running process, the utility model provides the coupling, which comprises a rubber tube and two hoops; two ends of the rubber tube are respectively sleeved at two shaft end parts to be connected; the two hoops are respectively sleeved at the two ends of the rubber tube so as to realize the fixed connection between the rubber tube and the two shaft ends to be connected. Compared with the prior art, the connecting part of the utility model is changed into the rubber tube from a rigid joint; in this way, the utility model has enough elasticity to meet the high speed running conditions of the shaft. The coupling has the advantages of simple structure, light weight, convenient and fast manufacturing and assembling as well as reliable working. After the coupling is assembled and put into use, almost no maintaining work is needed and the service life is long; therefore, the maintenance cost is greatly reduced.
Description
Technical field
The utility model relates to the mechanical transmissioning technology field, is specifically related to a kind of coupling.
Background technique
In order to adapt to different needs, people have designed the numerous coupling of form, at present, the development of coupling technology is very ripe, such as, rigid coupling, gear type coupling, cross universal coupling, plum blossom elastic coupling flexible coupling etc. are applied in the mechanical transmission position of various different needs.
For with the crane hoisting system of motor as power source, exist spread of voltage and cause the too fast problem of motor speed, thereby the operation that hoists brings great unsafe factor to elevator, therefore, for preventing that existing master file system motor from causing uncontrollable serious accident because of the hypervelocity problem, add over speed switch at the master file motor shaft end,, effectively avoided potential potential safety hazard to prevent the motor hypervelocity.But what the installation of this over speed switch was adopted is rigid coupling, and in the high speed rotating process, the rigid joint position very easily produces wearing and tearing, and life cycle was less than one month, and maintenance cost is higher.
The model utility content
For solving above-mentioned rigid coupling problem easy to wear in the process of running up, the utility model provides a kind of coupling, and it has enough elasticity and satisfies the condition that axle runs up.
The technical solution of the utility model is achieved in that and comprises rubber pipe and two clips, the two ends of described rubber pipe are set in diaxon end to be connected, described two clips are set with the two ends of described rubber pipe, to realize described rubber pipe and to wait to connect the fixedly connected of two axial ends.
Preferably, be interference fit between described rubber pipe and the diaxon end to be connected.
Preferably, described clip is specially hose clip.
Compared with prior art, point of attachment of the present utility model changes rubber pipe into by the rigidity catcher and connects, and like this, satisfies the condition that axle runs up with regard to enough elasticity is arranged.
Coupler structure described in the utility model is simple, in light weight, makes easy to assembly fast, has the advantage of the advantage reliable operation of reliable operation.Assembling finish come into operation after, need maintenance work hardly, therefore long service life greatly reduces maintenance cost.
Description of drawings
Fig. 1 is an overall structure schematic representation of the present utility model.
Embodiment
Specify preferred implementation of the present utility model below in conjunction with accompanying drawing.
Referring to Fig. 1, this figure is an overall structure schematic representation of the present utility model.
As shown in Figure 1, the utility model is made up of rubber pipe 1 and two clips 2; Wherein, the two ends of described rubber pipe 1 are set in diaxon end to be connected: motor side transmission shaft 3 and over speed switch transmission shaft 4, described two clips 2 are set with the two ends of described rubber pipe 1, to realize described rubber pipe 1 and to wait to connect the fixedly connected of two axial ends.
Further, be interference fit between the external diameter of the internal diameter of described rubber pipe 1 and two axial ends to be connected, magnitude of interference is for best about 1mm.Like this, after disposable being in place, in daily using process, need maintenance work hardly.
By above-mentioned illustrative embodiments as can be known, technological scheme described in the utility model is not limited thereto.For the one of ordinary skilled in the art, under the situation that does not break away from flesh and blood of the present utility model, can make different modification and improvement, use needs as long as satisfy, all in protection domain of the present utility model.
