Bushing and the direct gap of idle gear shaft are small, and lubricating oil flow speed is slower, so when the PTO gear assemblies of engine carry out long
Between high-power output when, the friction pair of idle gear component may cooling and lubricating deficiency, so as to cause bushing premature abrasion, very
To the failure of locking excessively heated axle, vehicle cisco unity malfunction is ultimately resulted in.Simultaneously because bushing and idle gear use interference fit, this
So that the assembly technology difficulty of idle gear is larger.
The information for being disclosed in the background section is merely intended to increase the understanding to general background of the present utility model, and
It is not construed as recognizing or implies that the information structure has been existing well known to persons skilled in the art in any form
Technology.
Utility model content
The purpose of this utility model is to provide a kind of simple and reasonable idle gear component, idle gear component use
Needle roller and retainer component so that the bearing capacity of idle gear component is stronger.And idle gear shaft step indoor design tiltedly
The secondary alignment needle roller of oil duct lubricating movements and retainer component so that the lubrication of kinematic pair is more abundant.
To achieve the above object, the utility model provides a kind of idle gear component, including：Idle gear shaft, its periphery are
Pressure-bearing surface, the outside of the pressure-bearing surface have the catching step of radial protrusion, oblique oil duct are offered in the catching step；Needle roller and guarantor
Frame component is held, it uses gap to coordinate on the pressure-bearing surface of the idle gear shaft；And idle gear, it uses gap to coordinate
On the needle roller and retainer component；And pass through gear baffle and idle gear tightened bolt presses.
Preferably, in above-mentioned technical proposal, the oil inlet of oblique oil duct connects with the lubricating oil oil-feed oil duct of idle gear shaft, goes out
Hydraulic fluid port is opened in the catching step of the idle gear shaft and the transition position of pressure-bearing surface.
Preferably, in above-mentioned technical proposal, idle gear fastening bolt is three.
Preferably, in above-mentioned technical proposal, gear baffle offers corresponding with the lubricating oil oil-feed oil duct of idle gear shaft
Oil-out.
Compared with prior art, the utility model has the advantages that：The idle gear component uses needle roller and holding
Frame component so that the bearing capacity of idle gear component is stronger.And in the oblique oil duct lubrication fortune of step indoor design of idle gear shaft
Dynamic secondary alignment needle roller and retainer component so that the lubrication of kinematic pair is more abundant.Simultaneously because the pressure-bearing of idle gear shaft
Without oil-out on face, this may be such that the bearing capacity of idle gear component improves significantly.

Embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described in detail, it is to be understood that this practicality
New protection domain is not limited by embodiment.
Explicitly indicated that unless otherwise other, otherwise in entire disclosure and claims, term " comprising " or its change
Change such as "comprising" or " including " etc. and will be understood to comprise stated element or part, and do not exclude other members
Part or other parts.
As shown in Figure 3 and Figure 4, included according to the concrete structure of the idle gear component of the utility model embodiment：
Idle gear shaft 21, needle roller and retainer component 22, idle gear 23, gear baffle 24 and idle gear fastening bolt 25.Wherein, needle roller
And the Internal and external cycle of retainer component coordinates mounting means with idle gear shaft, idle gear using gap, the lubricating oil of engine enters
After the oil duct for entering idle gear shaft, kinematic pair obtains that lubricating oil is more, it is relative before scheme, the effect of cooling and lubricating obtains very big
Raising, so as to solve premature abrasion, locking excessively heated axle failure.In addition, new departure idle gear is cleverly in catching step
Portion devises oblique oil duct, the oil-out alignment needle roller and retainer component of oblique oil duct, may be such that the lubrication of kinematic pair more
Fully.Simultaneously because without oil-out on the pressure-bearing surface of idle gear shaft, this may be such that the bearing capacity of idle gear component significantly
Improve.
Specifically, the periphery of idle gear shaft 21 is pressure-bearing surface, for being set with needle roller and retainer component 22 and idle gear
23.The outside of the pressure-bearing surface has the catching step of radial protrusion, and oblique oil duct 26 is offered in the catching step, oblique oil duct 26
Oil inlet connects with the lubricating oil oil-feed oil duct of idle gear shaft, and oil-out is opened in the catching step and pressure-bearing surface of idle gear shaft 21
Transition position, be directed at needle roller and retainer component, may be such that the lubrication of kinematic pair is more abundant.Simultaneously because idle gear shaft
Pressure-bearing surface on without oil-out, this may be such that the bearing capacity of idle gear component improves significantly.
Idle gear 23 is set on the pressure-bearing surface of idle gear shaft 21 by needle roller and retainer component 22, and kept off by gear
Plate 24 and idle gear fastening bolt 25 compress.The catching step of gear baffle 24 and idle gear shaft 21 coordinates from both ends to idle gear
23 progress are spacing.Wherein, needle roller and retainer component 22 coordinate installation side with idle gear shaft 21, idle gear 23 using gap
Formula, after the lubricating oil of engine enters the lubricating oil oil-feed oil duct of idle gear shaft, the oblique oil duct passed through in idle gear shaft step sprays
Go out, cooling and lubricating directly is carried out to needle roller and retainer component.Due to needle roller and retainer component and idle gear shaft, idle gear it
Between small―gap suture be present, so kinematic pair obtains, lubricating oil is more, it is relative before scheme, the effect of cooling and lubricating obtains very big
Improve, so as to solve premature abrasion, locking excessively heated axle failure.Further, it is that interference is matched somebody with somebody between the bushing and idle gear of former scheme
Close, it is necessary in low temperature environment, and need special frock to be assembled, and the needle roller and retainer component that new departure uses
Internal and external cycle is that small―gap suture coordinates, and under normal temperature, does not need frock to complete to assemble, reduces production cost.
In addition, this programme employs needle roller and retainer component (standard component), its hardness are higher than the bushing of scheme before, institute
Improved significantly with the bearing capacity of idle gear component.
Preferably, idle gear fastening bolt 25 is three.Gear baffle 24 offers the lubricating oil oil-feed with idle gear shaft
Oil-out corresponding to oil duct.
To sum up, the idle gear component uses needle roller and retainer component so that the bearing capacity of idle gear component is stronger.And
In the secondary alignment needle roller of the oblique oil duct lubricating movements of the step indoor design of idle gear shaft and retainer component so that the profit of kinematic pair
Sliding cooling is more abundant.Simultaneously because without oil-out on the pressure-bearing surface of idle gear shaft, this may be such that holding for idle gear component
Loading capability greatly improves.
The foregoing description to specific illustrative embodiment of the present utility model is to illustrate and the purpose of illustration.These
Description is not wishing to for the utility model to be defined to disclosed precise forms, and it will be apparent that according to above-mentioned teaching, can carry out
It is many to change and change.The purpose of selecting and describing the exemplary embodiment is that explain certain principles of the present utility model
And its practical application, so that those skilled in the art can realize and utilize a variety of examples of the present utility model
Property embodiment and various chooses and changes.The scope of the utility model is intended to by claims and its waits similar shape
Formula is limited.
