Gap can exist the accuracy of mesh between turbine and worm screw gear ring is worked into very high, and increase processing in this way
Cost, since turbine and worm screw are in engagement, existing gap between gear ring, to drive turbine by worm screw when motor works
When rotation, have the shortcomings that noise is big, and when worm screw rotation, after eliminating the gap between gear ring, then in rotary course suddenly
With the gear ring rigid contact of turbine, work also reduces the service life of entire tripod turnstile so for a long time.
Utility model content
To solve problems of the prior art, the purpose of the utility model is to provide a kind of turbines of tripod turnstile machine core
Shaft assembly, which can effectively eliminate the gap between worm screw and turbine gear ring, to make tripod turnstile in the course of work
In have the advantages that low noise, and also improve the service life of tripod turnstile to a certain extent.
A kind of in order to achieve the above purposes, the technical solution adopted by the utility model is: turbine shaft assembly of tripod turnstile machine core,
Including turbine wheel shaft and turbine mechanism, the turbine mechanism includes the fixed turbine and movable turbine coaxial with the turbine wheel shaft, institute
It states fixed turbine to be structure as a whole with the turbine wheel shaft, the activity turbine is movably set in the turbine wheel shaft against fixed turbine
On；The inner peripheral surface of the activity turbine is equipped at least one first groove, the outer circumference surface of the turbine wheel shaft be equipped with
The second groove that first number of recesses is equal and position is opposite is equipped with spring between first groove and the second groove,
When the spring in a free state, the first groove and the second groove face, and the fixed turbine and movable turbine at this time
Gear ring on outer circumference surface is staggered.
As a preferred embodiment, the turbine shaft assembly of the tripod turnstile machine core further includes being arranged in the turbine wheel shaft
On shaft retaining ring, the shaft retaining ring is set to movable side of the turbine far from fixed turbine.
It is multiple when the quantity of first groove and the second groove is multiple as another preferred embodiment
First groove is distributed on the inner peripheral surface of the movable turbine, and multiple second grooves are distributed in the turbine wheel shaft
On outer circumference surface.
The beneficial effects of the utility model are: the spring between the first groove of the utility model and the second groove is in freely
When state, the first groove and the second groove face, and the gear ring staggered row on fixed turbine and movable turbine outer circumference surface at this time
Column, can effectively eliminate the gap between gear ring, can be effectively reduced through this structure tripod turnstile during the work time due to
The big disadvantage of noise caused by gap between the gear ring of worm and gear, and extend the service life of tripod turnstile.

Specific embodiment
The embodiments of the present invention are described in detail with reference to the accompanying drawing.
Embodiment
As Figure 1-Figure 4,1 component of turbine wheel shaft of a kind of tripod turnstile machine core, including turbine wheel shaft 1 and turbine mechanism, it is described
Turbine mechanism includes the fixed turbine 2 and movable turbine 3, the fixed turbine 2 and the turbine wheel shaft coaxial with the turbine wheel shaft 1
1 is structure as a whole, and the activity turbine 3 is movably set on the turbine wheel shaft 1 against fixed turbine 2；The activity turbine 3
Uniformly distributed there are four the first groove 4 on inner peripheral surface, the outer circumference surface of the turbine wheel shaft 1 is equipped with and 4 quantity of the first groove
The second equal and opposite position groove 5 is equipped with spring 6, at the spring 6 between first groove 4 and the second groove 5
When free state, 5 face of the first groove 4 and the second groove, and the fixed turbine 2 and 3 outer circumference surface of movable turbine at this time
On gear ring be staggered；1 component of turbine wheel shaft of the tripod turnstile machine core further includes the shaft retaining ring 7 being arranged on the turbine wheel shaft 1,
The shaft retaining ring 7 is set to side of the movable turbine 3 far from fixed turbine 2.
The working principle of the present embodiment is described further below:
As shown in Figure 1, it is recessed that spring 6 is installed on the first groove 4 and second after movable turbine 3 is sheathed on turbine wheel shaft 1
In gap between slot 5, then the card of shaft retaining ring 7 is set on turbine wheel shaft 1 and blocks movable turbine 3, when spring 6 is in such as Fig. 3 institute
When the free state shown, 5 face of the first groove 4 and the second groove, the movable gear ring of turbine 3 and the gear ring of fixed turbine 2 at this time
It is staggered, the gap between turbine mechanism and worm screw gear ring can be effectively eliminated, when motor, which works, drives worm screw rotation, worm screw
It drive activity turbine 3 can rotate first, movable turbine 3 can compress the spring between the first groove 4 and the second groove 5 when rotating
6, when spring 6 is compressed to a certain degree, as shown in figure 4, spring 6 at this time is in running order, the gear ring of movable turbine 3
Gear ring with fixed turbine 2 will be just opposite, this process spring 6 plays good buffer function, and when motor stops
When work, spring 6 restores to original state, and the gear ring of movable turbine 3 and fixed turbine 2 is made to be alternately arranged elimination gear ring again
Between gap, tripod turnstile can be effectively reduced through this structure during the work time due between the gear ring of worm and gear
The big disadvantage of noise caused by gap, and extend the service life of tripod turnstile.
Specific embodiment of the present utility model above described embodiment only expresses, the description thereof is more specific and detailed,
But it should not be understood as limiting the scope of the patent of the utility model.It should be pointed out that for the common of this field
