Description
Technical field
The utility model belongs to field of mechanical technique, is related to a kind of differential mechanism, in particular to a kind of differential mechanism and driven tooth
The connection structure of wheel.
Background technique
Differential mechanism is a kind of mechanical device operated by planetary gear set for realizing left and right sidesing driving wheel with different rotating speeds,
It is mainly made of left and right axle shaft gear, two planetary gears and tooth rest, same size can be distributed by two jack shafts to the left and right
Torque.The two sides of driven gear are mainly connected with tooth rest and fluted disc, it is therefore necessary to open up use on the flank of tooth of driven gear
In the screw hole of connection, conventional connection type is to open up two secondary different screw holes on the flank of tooth to be respectively used to tooth rest and tooth at present
The connection of disk has the disadvantage that although the structure versatility is higher since the screw hole opened up on the flank of tooth is more,
Driven gear is easy to produce stress fracture, keeps the stability of product poor, service life is low.
Summary of the invention
The purpose of this utility model be for the above-mentioned problems in the prior art, provide it is a kind of overall structure not
The connection structure of differential mechanism and driven gear that the quantity that screw hole on driven gear is reduced in the case where change keeps the flank of tooth firmer.
The purpose of this utility model can be realized by the following technical scheme: a kind of connection knot of differential mechanism and driven gear
Structure, including tooth rest, driven gear and fluted disc, the inside of the tooth rest are symmetrically equipped with planetary gear and half axle gear respectively
It takes turns and is intermeshed, which is characterized in that the flank of tooth center of the driven gear offers circular groove, uniformly opens in circular groove inner circumferential
Equipped with a circle screw hole one, the fluted disc is fixed on the back side of driven gear by the cooperation of flat head screw and screw hole one, described
Screw hole two is offered on the screw rod of flat head screw, the tooth rest is arranged in circular groove and by hexagon socket head cap screw and screw hole two
Cooperation be fixed on the front of driven gear.
In the connection structure of this differential mechanism and driven gear, fluted disc is first fixed on to the back of driven gear by flat head screw
Face, then cooperated by hexagon socket head cap screw with the screw hole two on flat head screw screw rod and fix tooth rest, relative to traditional connection
Structure, the utility model have only opened up a circle screw hole in driven gear, and quantity only has conventional half, therefore the knot of the face of gear
Structure is more firm not easy to break, and if necessary can be with the diameter of overstriking flat head screw screw rod, convenient for opening up for screw hole two, In
The diameter probability that its stress fracture occurs compared with opening up two screw holes for increasing single screw hole in practical application is smaller.
In the connection structure of a kind of above-mentioned differential mechanism and driven gear, the hexagon socket head cap screw is tight by tooth rest
Gu there are gaps between two bottom surface of screw hole after.
In the connection structure of a kind of above-mentioned differential mechanism and driven gear, it is mounted in the tooth rest and fluted disc
Bearing.
In the connection structure of a kind of above-mentioned differential mechanism and driven gear, the back side of the driven gear offers a circle
Card slot, the fluted disc cooperation are arranged in card slot.
Compared with prior art, the connection structure of this differential mechanism and driven gear is by working as tooth rest and fluted disc stationary phase
In indirectly being fixed with driven gear, reduces the quantity of screw hole on half driven gear, therefore have stability more preferable, use
The advantages of longer life expectancy.

Specific embodiment
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
As shown in Figure 1 and Figure 2, the connection structure of this differential mechanism and driven gear, including tooth rest 1, driven gear 2 and tooth
Disk 3, the inside of tooth rest 1 are symmetrically equipped with planetary gear 4 and axle shaft gear 5 respectively and are intermeshed, wherein axle shaft gear 5
Inside offer spline, convenient for its connection between output shaft, the flank of tooth center of driven gear 2 offers circular groove 6, in circle
6 inner circumferential of slot uniformly offers a circle screw hole 1, and fluted disc 3 is fixed on driven by the cooperation of flat head screw 8 and screw hole 1
The back side of gear 2, screw hole 29 is offered on the screw rod of flat head screw 8, and tooth rest 1 is arranged in circular groove 6 and by interior hexagonal spiral shell
The front of driven gear 2 is fixed in the cooperation of silk 10 and screw hole 29.
