Description
Technical field
It is more particularly to a kind of to can be used for flexible locking two grades of circles of building hoist the present invention relates to mechanical transmission fields
Cone-cylinder gear speed reducer.
Background technology
It is the converter that motor speed conversion is realized using gear that decelerator is mainly, using quite varied, greatly to vapour
In car, ship, construction equipment and the equipment of industrial product, the small transmission system to the various machineries such as our household electrical appliances, can all apply to
Decelerator.Building hoist is essential plant equipment in building trade, the capital equipment of building hoist mechanism section
It is exactly decelerator, domestic construction lifter reducer mainly has Worm-gear type decelerator, planet gear transmission speed reduction at present
Three kinds of forms of device and cylinder gear speed reducer, but there is certain, worm gear in actual applications in these three decelerators
The defect of Worm type decelerator is：The larger, speed of service of being generated heat after less efficient, continuous work is relatively low；Planetary gearing speed reducer
With apparent operational shock and the problems such as bad decelerator stress；Cylinder gear speed reducer is also because the reasons such as shake could not be wide
General application.
Because in the organization plan of above-mentioned conventional decelerator, hub class part is fixed and positioned using tradition on axle
Fastening schemes, for example with axle sleeve, shaft shoulder etc. rigidity tightening member.But building hoist longtime running is in low-speed heave-load and punching
Hit under load frequency of occurrences operating mode higher, rigid tightening member permanent deformation occurs under the repeated action of shock loading, from
And it is unintelligible to cause decelerator hub class part axial to position, when building hoist runs, there is the axial play of hub class part,
So that there are a series of defects such as vibrate, stress is bad, construction safety accident is even resulted in.
With being continuously increased for building height, skyscraper is more and more, to the stable of construction lifter reducer
Property require also more and more higher, in the urgent need to a kind of decelerator for using New anti-loose method is to solve above-mentioned deficiency.
The content of the invention
It is an object of the invention to overcome the decelerator in existing building hoist to make due to being frequently subject to shock loading
Axial stiffness setting element deformation inside decelerator, and then hub class part is produced axial play, cause vibration, stress bad
Etc. above-mentioned deficiency, there is provided a kind of flexible locking gear reduction unit for building hoist, by the hub class zero in decelerator
It is locking that part carries out axial elasticity so that decelerator can absorb the instantaneous energy of shock loading when by shock loading, can be with
It is reduced or avoided when decelerator works the problems such as the deformation caused by the rigid fastening schemes of itself, loosening, vibration, raising
Decelerator job stability and reliability.
To achieve these goals, the technical solution adopted by the present invention is：
A kind of flexible locking gear reduction unit for building hoist, comprising casing, be provided with the casing input shaft,
Jackshaft and output shaft, the input shaft are arranged on casing by a bearing of input shaft, and the output shaft is defeated by two
