Abstract
Disclosed by the utility model is a kind of three tooth connection structures, including triple gear and output shaft, the end face of the triple gear is equipped with placing groove, plane bearing is equipped in the placing groove, the output shaft is equipped with gear part, the output shaft passes through triple gear, and the gear part is located at outside triple gear, and the end face of the gear part is in contact with the washer of plane bearing.It is the utility model structure novel, ingenious in design, it is separated by plane bearing between the gear part and triple gear of the output shaft, when output shaft is in rotation, the end face of gear part can drive the washer of plane bearing also to generate corresponding movement, the friction that only will produce very little between the washer of gear part and plane bearing in this way, to reduce gear part and plane bearing washer abrasion.
Description
Technical field
The utility model is related to auto parts fields, in particular to a kind of three tooth connection structures.
Background technology
Automobile differential is the important composition accessory of automobile, and left and right (or forward and backward) driving wheel can be made to realize with difference
The mechanism of rotational speed.Automobile differential is mainly made of three teeth, planetary gear, axle shaft gear and output shaft etc., described
Three teeth, planetary gear and axle shaft gear engage successively, and the output shaft sequentially passes through three teeth, planetary gear and half axle gear
Wheel, the output shaft are equipped with gear part, and the end face of three tooth is equipped with gasket placing groove, the placing groove and gear part phase
It is adapted to and is placed with gasket, the end face of the gear part and the end face of gasket are inconsistent.With the rotation of output shaft, gasket
Can soon be worn so that connected between output shaft and three teeth it is unstable, to influence the use of entire automobile differential.
Utility model content
Provided by the utility model is a kind of three tooth connection structures, and main purpose is to overcome of the existing technology
The above problem.
The utility model adopts the following technical scheme is achieved：
A kind of three tooth connection structures, including triple gear and output shaft, the end face of the triple gear, which is equipped with, to be put
Slot is set, plane bearing is equipped in the placing groove, the output shaft is equipped with gear part, which passes through triple gear, described
Gear part is located at outside triple gear, and the end face of the gear part is in contact with the washer of plane bearing.
Further, it is equipped with the rolling bearing coordinated with output shaft in the triple gear, is equipped in the triple gear
Card slot, the card slot are equipped with the clamp spring for fixing rolling bearing.
Further, the plane bearing is plane needle bearing.
Further, the rolling bearing is needle bearing.
From the above description of the utility model, it can be seen, compared to the prior art, the utility model has the following advantages that：This
It is utility model structure novel, ingenious in design, it is separated by plane bearing between the gear part and triple gear of the output shaft, when
For output shaft in rotation, the end face of gear part can drive the washer of plane bearing also to generate corresponding movement, such gear part
The friction that only will produce very little between the washer of plane bearing, to reduce gear part and plane bearing washer mill
Damage.The utility model avoids existing the problem of causing gasket rapid wear using gasket after improvement so that output shaft
The stability connecting is kept between triple gear.
Description of the drawings
Fig. 1 is the schematic cross-sectional view of the utility model.
Fig. 2 is the schematic cross-sectional view of the utility model triple gear.
Specific implementation mode
Referring to Figures 1 and 2.A kind of three tooth connection structures, including triple gear 1 and output shaft 2.The triple gear
1 end face is equipped with placing groove 11, and plane bearing 3 is equipped in the placing groove 11.The output shaft 2 is equipped with gear part 21, should
Output shaft 2 passes through triple gear 1, and the gear part 21 is located at outside triple gear 1, and the end face and plane axis of the gear part 21
3 washer is held to be in contact.The plane bearing 3 is plane needle bearing, and plane needle bearing dish is increased with high-precision needle roller
Contact length so that this bearing can get high loadability and high rigidity under the space of very little.
Referring to Figures 1 and 2.The rolling bearing 4 coordinated with output shaft 2, the triple gear are equipped in the triple gear 1
Card slot 12 is equipped in 1, which is equipped with the clamp spring 5 for fixing rolling bearing 4.The rolling bearing 4 is needle bearing,
Friction between 1 inside of output shaft 2 and triple gear can be reduced using rolling bearing 4.
Referring to Fig.1.The design principle of the utility model is as follows：Between the gear part 21 and triple gear 1 of the output shaft 2
It is separated by plane bearing 3, when output shaft 2 is in rotation, the end face of gear part 21 can drive the washer of plane bearing 3 also to produce
Raw corresponding movement, only will produce the friction of very little, to reduce tooth between such gear part 21 and the washer of plane bearing 3
The abrasion of wheel portion 21 and the washer of plane bearing 3.
The above is only the specific embodiments of the present invention, but the design concept of the present invention is not limited thereto,
All non-essential modifications to the present invention made by this concept should all belong to the row for invading scope of protection of the utility model
For.
