Abstract
The utility model discloses a kind of gearbox shaft end structures, including end cap, spacer I, hasp ring, spacer II and axis；The hardness of spacer I and spacer II reaches suitable with hasp ring hardness.The hardness and wearability of the inner peripheral surface of spacer I are suitable with the hardness of axis and wearability.The inner ring of spacer I is installed on by interference fit on axis so that the two keeps opposing stationary；The outer peripheral surface of spacer II is installed on by interference fit in the endoporus of end cap so that the two keeps opposing stationary；Hasp ring is installed in the slot of II outer surface of spacer so that end cap avoids direct rotating contact with axis.This fabricated construction is more using interference fit installation, and structure is relatively easy, easy to implement.
Description
Technical field
The utility model is related to a kind of a kind of shaft end structures applied on engineering machinery fixed shaft type speed-changing gear box.
Background technology
Currently, rotatory sealing is mostly used and is taken between engineering machinery fixed shaft type speed-changing gear box shaft end oil inlet end cover and axis
Button sealing ring, hubcap mostly use cast iron process part, and hardness is relatively low, wears no resistance, and buckle type sealing ring and axis are height
Hardened material, in axis runs at high speed, hubcap is easy to wear and cause the seal failure of sealing ring.And since axis is adopted more
Cause its spin friction coefficient larger with the materials variances between hardened steel, with cast iron end cap, do not only result in the abrasion of end cap,
And abrasion fever is caused to lead to the increase of power loss.
Invention content
The purpose of this utility model is to provide a kind of Novel shaft simple in structure, wear-resistant, reliability is high, power loss is small
End structure.
What the purpose of this utility model was realized in：
A kind of gearbox shaft end structure, including end cap, spacer I, hasp ring, spacer II and axis；The spacer I is mounted on axis
On so that the two keeps opposing stationary；The spacer II is mounted in the endoporus of end cap so that the two keeps opposing stationary；Institute
It states hasp ring to be installed in the slot of II outer surface of spacer so that end cap avoids direct rotating contact with axis.
Preferably, the inner ring of the spacer I is installed on by interference fit on axis.
Preferably, the outer peripheral surface of the spacer II is installed on by interference fit in the endoporus of end cap.
Preferably, the hardness of the inner peripheral surface of the spacer I and wearability are suitable with the hardness of axis and wearability.
Preferably, the hardness of the spacer I and spacer II reaches suitable with hasp ring hardness.
The utility model advantageous effect：
Since the utility model uses above-mentioned fabricated construction, simple in structure, end cap avoids direct rotating contact with axis,
Avoid abrasion；The hardness of spacer I and spacer II reach with hasp ring hardness, during relative rotation friction coefficient compared with
It is small, the reliability and service life of hasp ring are improved, and reduce power loss.
Description of the drawings
Fig. 1 is the structure chart of the utility model.
1- end caps, 2- spacers I, 3- hasps ring, 4- spacers II, 5- axis in figure.
Specific implementation mode
Below in conjunction with attached drawing, the utility model is further described by specific implementation mode.
As shown in Figure 1, a kind of gearbox shaft end structure, including end cap 1, spacer I 2, hasp ring 3, spacer II 4 and axis 5；Every
Covering I 2 uses mild steel carburizing and quenchings, spacer II 4 that mild steel carburizing and quenching, the hardness of spacer I 2 and spacer II 4 is used to reach
It is suitable with hasp ring hardness.The hardness and wearability of the inner peripheral surface of spacer I 2 are suitable with the hardness of axis 5 and wearability.Spacer I 2
Inner ring by interference fit be installed on axis 5 so that the two keep it is opposing stationary；The outer peripheral surface of spacer II 4 passed through
Cooperation of being full of is installed in the endoporus of end cap 1 so that the two keeps opposing stationary；Hasp ring 3 is installed on the slot of II 4 outer surface of spacer
It is interior so that end cap 1 avoids direct rotating contact with axis 5.In relative motion, the abrasion of end cap 1 greatly reduces, and improves end cap
1 and hasp ring 3 service life and reliability；Spacer I 2, hasp ring 3, the spacer II 4 of relative rotation contact, spacer I 2
It is all made of mild steel carburizing and quenching with spacer II 4, friction coefficient substantially reduces, and reduces the power damage in rotational movement process
It loses.This fabricated construction is more using interference fit installation, and structure is relatively easy, easy to implement.
Above are merely preferred embodiments of the utility model, it should be pointed out that：For the ordinary skill people of the art
For member, without departing from the principle of this utility model, several improvements and modifications can also be made, these improvements and modifications
Also it should be regarded as the scope of protection of the utility model.
