Abstract
The invention provides a coupling. The coupling is characterized in that a half connecting groove is formed in an annular gear, a rotating shaft is inserted into the half connecting groove, the half connecting groove is used for controlling the clearance of the rotating shaft so as to reduce vibration of the rotating shaft in the annular gear and to also reduce the angular displacement deviation and the radial displacement deviation of the rotating shaft, and meanwhile, due to limitation of the half connecting groove, the rotating shaft and a driven shaft are horizontally concentric, the rotation and transfer power of both the rotating shaft and the driven shaft is effectively and steadily transferred, excessive swinging amplitude of the coupling due to vibration is reduced, and the transmission efficiency is improved. Moreover, as the driven shaft is fastened to the interior of an inner connecting groove of a shaft sleeve by bolts, and a thermal insulation gasket is arranged at the joint between bolts by which the driven shaft is fixed and the inner connecting groove. Due to the use of the thermal insulation gasket, one end of the driven shaft can be sealed better, at the same time, favorable heat resistance, pressure resistance and compression-recovery performance are achieved, and the service life of the coupling is prolonged.
Description
Technical field
The present invention relates to a kind of shaft coupling.
Background technology
The shaft coupling used on crane has two types, and one is the size gear coupling being exposed；Two is closed gear shaft coupling.Wherein exposed gear shaft coupling, is used for low speed rotation system.Deceleration device in the cart drive system of the old-fashioned crane that the past produces, is all this exposed gear shaft coupling.Owing to its travelling gear is all exposed, easily enter dust, poor lubrication, so gear is easy to wear.In the decelerator of enclosed construction, gear is incorporated in airtight shell, and dust enters not go, and lubrication is good.Owing to decelerator lubricating condition is good, easy to maintenance, use durable, so on current crane, the deceleration device of the afterbody of big elevating capacity still adopting exposed gear shaft coupling.And exposed gear shaft coupling exists following problem: the noise that (1) is uneven, mainly rotor helical-screw angle is inconsistent, or axis not parallel caused by.(2) interrupted and clear and melodious strike note, mainly rotates shaft connection place open, and destroked space limits.(3) driven shaft insufficient lubrication poor heat resistance.
Summary of the invention
For solving above-mentioned technical problem, the invention provides a kind of shaft coupling, its objective is to provide a kind of simple in construction, size is little, easy to manufacture need not lubricate again, dismounts simple shaft coupling.
A kind of shaft coupling, it includes rotating axle, the described side rotating axle is provided with half access slot, described rotation axle inserts in half access slot, and half described access slot is socketed in ring gear, and described ring gear and axle sleeve pass through bolt-connection, it is provided with driven shaft in described axle sleeve, described axle sleeve is provided with interior access slot, and of described driven shaft is arranged in this interior access slot, and one end of described driven shaft is provided with external screw thread and is fixed by driven shaft by bolt.
Preferably, described rotation and driven shaft two axle level are concentric.
Preferably, the link position of the end bolt of described driven shaft and interior access slot is provided with heat insulating mattress.
Preferably, described heat insulating mattress is ceramic fibre paper gasket.
A kind of shaft coupling provided by the invention, it has the beneficial effects that: is provided with half access slot in ring gear and is plugged in half access slot by rotation axle, half described access slot is for controlling to rotate the gap of axle, reduce the vibration rotating axle at ring gear, reduce the angular displacement deviation and radial displacement deviation that rotate axle, simultaneously because the restriction of half access slot, make to rotate the horizontal concentricity of axle and driven shaft, make to rotate axle and driven shaft revolution and transmission power effectively transmits smoothly, reduce vibration and cause that the amplitude of fluctuation of shaft coupling is excessive improves transmission efficiency；Have again, driven shaft is anchored in the interior access slot of axle sleeve by bolt by driven shaft, in order to the fixing position with interior access slot at fixing driven shaft is provided with heat insulating mattress, driven shaft one end is sealed better by the use of this heat insulating mattress, there is well thermostability, pressure performance and compression recovery performance simultaneously, extended the service life of shaft coupling.
Accompanying drawing explanation
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below.
