Abstract

A gap-fee gear driving mechanism comprises a drive wheel 6 arranged on the drive shaft and driven wheels 1, 2 arranged on the driven shaft. The utility model is characterized in that the driven wheels 1,2 comprises main gears 1 and deputy gears 2 which are stuck to each other; a ring-shaped groove is arranged on the sticking face between the main gear 1 and the deputy gear 2; a non-closed ring-shaped elastic element 4 is arranged a the groove 7; a pin 3 is fixed on the sticking face of the main gear 1 and another pin 3 is also fixed on the sticking face of the deputy gear 2; the pins 3 are all arranged in the groove 7 after assembly; the elastic element 4 is arranged between the two pins 3, and the two ends of the elastic element 4 are tightly stuck to the two pins 3. Holes are all arranged on the equal circles of the main gear 1 and the deputy gear 2, and the main gear 1 and the deputy gear 2 are assembled together by a positioning shaft passing through the holes.

Description

No gap gear drive

One, technical field

The utility model belongs to a kind of gear transmission (containing the turbine and worm transmission) mechanism.

Two, background technique

General gear transmission, because there are manufacture deviation in gear and mounting center distance, a pair of gear pair wheel between cog certainly exists the gap.In the gear transmission, because variation of temperature, this gap also changes thereupon.Because the existence in this gap, when gear rotational speed changes, gear pair wheel between cog will produce impact, can cause the gear teeth to destroy when serious; To produce serious noise simultaneously, cause environmental pollution.

Three, summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, adopts a kind of simple structure to eliminate the gap of gear pair, effectively reduces impact and noise in the transmission.

The utility model is achieved in that

A kind of no gap gear drive comprises it is characterized in that driving wheel that is loaded on the driving shaft and the follower that is loaded on the driven shaft:

One of A, driving wheel or follower are made of the master gear and the pinion that paste mutually;

B, on the phase veneer of master gear and/or pinion, have groove, elastomer is housed in the groove;

C, all be fixed with a pin on the veneer mutually of master gear and pinion, assembling back pin all is arranged in groove;

D, elastomer between two pins and the elastomer two ends can be close to two pins.

Further scheme is, all can have the hole in case of necessity on the equal circumference of master gear and pinion, and passes the hole by positioning shaft master gear and pinion are assembled together.

Further scheme is, described groove is a circular groove.

Further scheme is that described groove is a straight trough again.

The utility model content is a kind of no gap gear drive, in this organization gear transmission process, no gap transmission between gear pair, and can compensate the gap variation (not having the gap all the time) that gear causes because of temperature variation, thus effectively reduced impact and the noise in the transmission.Be fit to spur gear pair, helical gear pair, herringbone tooth wheel set, the cone gear pinion kind of drive and turbine and worm auxiliary driving mode.Can effectively reduce the impact and the noise of wheel between cog in the transmission.

Five, implementation

As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, a kind of no gap gear drive comprises it is characterized in that driving wheel 6 that is loaded on the driving shaft and the

follower

1,2 that is loaded on the driven shaft:

Follower

1,2 is made of the master gear 1 and the pinion 2 that paste mutually;

On the veneer mutually of master gear 1 and pinion 2, have circular groove 7, non-closed circular elastomer 4 is housed in the groove 7;

All be fixed with a pin 3 on the veneer mutually of master gear 1 and pinion 2, assembling back pin 3 all is arranged in groove 7;

Elastomer 4 two the pin 3 between and elastomer 4 two ends be close to two the pin 3.

On the equal circumference of master gear 1 and pinion 2, all have pilot hole, and pass the hole by positioning shaft 5 master gear 1 and pinion 2 are assembled together.

Further specify as follows:

A pin 3 is installed respectively on driven master gear 1, the pinion 2, an elastomer 4 is installed between pin 3, under the effect of elastomer 4 tension force, driven master gear 1, pinion 2 have the trend that along the circumferential direction staggers mutually.During installation, driven master gear 1, pinion 2 relies on positioning shaft auxiliary bolt 5 be assembled together (as same independent gear), driven master gear 1, pinion 2 cooperate with driving gear 6 install after, take off auxiliary bolt 5, under the tension force effect of elastomer 4, driven master gear 1 and pinion 2 stagger mutually, and each is contacted its gear teeth with driving gear 6 gear teeth by one side, thereby eliminate gap between gear.When the working gear temperature variation, increase (or minimizing) distortion by elastomer 4 and eliminate the gap variation that causes because of temperature variation.

Fig. 6, Fig. 7, Fig. 8, Fig. 9 have provided another kind of implementation of the present utility model.Elastomer 4 is for placing the spring between two pins 3 among the figure.Remaining part is identical with aforementioned embodiments.
