Description
Technical field
The present invention relates to a kind of speed changes without chain drive assembly.
Background technique
The hand crank transmission device (assembly) of existing compact shelving bookshelf etc., usually has chain drive structure and without chain drive
Structure etc. is several, and relative to no chain drive structure, chain drive structure is primarily present, power transmission low with respect to transmission efficiency
It is weak, the problems such as operational reliability.But its reasonability for totally constituting of existing no chain gear transmission structure is inadequate, not only
The stability and reliability of its operation are influenced, and is mostly single transmission agency, to implement gear simultaneously, is then needed
In addition special speed change gear is set or in addition add more complicated gear on driver plate (assembly plate).This
Not only considerably increase transmission transmission loss；And making manual setter integrally and become complicated, reliability substantially reduces, maintenance dimension
Repair heavy workload；Meanwhile relative motion efficiency reduces, drive noise is big, and manufacturing cost increases.
Summary of the invention
The purpose of the present invention is in view of the deficiency of the prior art, provide a kind of speed change without chain drive assembly.
It is extremely simple, scientific, reasonable that the speed change is formed without chain drive assembly structure, has that gear driving is multi-functional, and operation is steady
Fixed reliable, power transmission loss is small.
Technical solution of the speed change of the present invention without chain drive assembly includes intellectual input driver structure, the input transmission
Mechanism includes several incoming spur gears being connected on input shaft, be passed to angular wheel, be connected to corresponding transmission shaft,
With the outflow angular wheel of the incoming angular wheel transmission connection, and to coaxially connected corresponding of the incoming angular wheel
Several outflow spur gears, the two incoming spur gear and the corresponding transmission connection of corresponding outflow spur gear.
The input shaft, which is equipped on the incoming conical tooth wheel shaft of the two incoming spur gears, is provided with corresponding two outflows straight-tooth
Wheel.
The two incoming spur gears and the two outflow spur gear difference numbers of teeth are different.
The input shaft is staged input shaft.
It can not only realize that a variety of power such as speed-changing braking locking pass to speed change of the invention simultaneously without chain drive assembly
Defeated mapping function, especially its whole gear structure are very simple, increase transmission components without additional, in basic power
Naturally speed change is realized in transmission transmission process, transferring drive structure and corresponding transferring drive methods are simple, science, close
Reason, drive mechanism is highly stable, accurate, reliable, can obtain preferably power transmission characteristic and transmission performance relatively, higher
Transmission efficiency is high, and applicable loading range is big, and transmission loss is small, adaptable, is not only applicable in general load, is also applicable to height
Fast heavy duty is, it can be achieved that compared with large transmission ratio, laborsaving, run smoothly low noise.

The mutual not phase of the size or the corresponding number of teeth of its two incoming spur gear (i.e. incoming spur gear one and incoming spur gear two)
Together, the correspondingly sized or corresponding number of teeth of outflow spur gear one and outflow spur gear two is different accordingly.Staged input
Axis 4 and incoming conical tooth wheel shaft 5 and its corresponding two incoming spur gear and two outflow spur gears form input transmission gear shift.Change
Corresponding incoming, outflow spur gear diameter or gear ratio, i.e. change gear ratio.
Brake is set to the middle part of transmission shaft by corresponding fixed plate 7.Brake includes braking lock 9 and total lock 8, with
And it is fixed on the corresponding braking sprocket wheel 10 of transmission shaft corresponding site.Braking lock can be only arranged in brake.The brake also may be used
It is similar with existing relevant apparatus.
The both ends of transmission shaft pass through corresponding bearing arrangement respectively or bearing holder (housing, cover) is connected to input rack 2 and output bracket
12.The middle part of transmission shaft is connected to assembly plate by a vertical bearing seat 11 and its corresponding vertical bearing seat board.
As shown in figure 3, when staged input shaft 4 is straight with outflow by when being manually pulled out (release), being passed to spur gear 2 17
For 23 engaged transmission cooperation of gear to reach another speed, remaining incoming spur gear of two outflows is vacant.
As shown in figure 4, being passed to spur gear 1 and outflow spur gear 1 when staged input shaft 4 is by manually advancing
