Description
Technical field：
The utility model is related to a kind of mini-tiller more particularly to a kind of axis installing mechanisms of mini-tiller.
Background technology：
Existing mini-tiller includes gearbox body, and clutch is provided in babinet, to make clutch work, need to be arranged one
Clutch yoke pushes the push-plate of clutch, and the clutch yoke need to be fixed on a clutch yoke axis.Therefore, existing
Have in technology, clutch yoke axis passes through the gearbox body and the clutch yoke, then connects with the clutch arm outside gearbox body
It connects, by driving the clutch arm so that the clutch yoke shaft rotation is dynamic, so that the clutch yoke on clutch yoke axis pushes away
Move the clutch push-plate so that clutch push-plate compresses the friction plate of clutch, make at clutch with working condition and will move
Power is transferred to speed changer.When needing to stop or shift gears, then clutch arm is driven to rotate the clutch yoke axis so that clutch yoke
Principle clutch push-plate so that push-plate stops pressing friction piece, stops the power output of clutch.
However in gearbox, machine oil is needed to be lubricated each axis of speed changer and each pair of gear pair, so that its is suitable
Smooth operation.Therefore, when the clutch yoke axis passes through the gearbox, there will be seam between axis and the via of gearbox
Gap so that lubricating oil leakage.In order to prevent lubricating oil leakage, the prior art from using technical solution below：Bushing is passed through into tooling
It is pressed into the installation via of gearbox, then O-ring seal is assembled in the seal groove of clutch yoke axis both sides, then by clutch
Shift fork axle is assembled in gearbox clutch yoke axis installation via, is positioned with retainer ring finally by axis.It reaches in this way
To the sealing to clutch yoke axis and gearbox, the leakage of machine oil is avoided.
But certain problem is still remained using existing mounting means：1, existing mounting means needs at least two
A bushing, it is known that the cost of a bushing is nearly 2 yuan, and then the cost of the installing mechanism can be caused to increase using two bushings
Nearly 4 yuan, for the relatively thin mini-tiller industry of profit, undoubtedly burden is increased to enterprise.2, in assembling process, it is arranged with
The clutch yoke axis of O-ring seal need to sequentially pass through the installation via of gearbox one side wall outside gearbox, into gearbox
The installation via of another side wall is then passed through after interior.And when clutch yoke axis is by the installation via across another side wall in gearbox
When, since chamfering can not be processed in babinet, easily occurs O-ring seal when mounted and cut bad situation, once it is O-shaped
Sealing ring is cut bad, then cannot achieve sealing effect, result in lubricating oil leakage.3, in addition, also easily being sent out using clutch yoke bushing
The deviation of raw installation accuracy, and then cause product unqualified.
Utility model content：
The purpose of this utility model is to provide axis installing mechanisms a kind of at low cost and high installation reliability.
To achieve the goals above, the utility model is realized in this way：A kind of axis mounting structure of mini-tiller, including case
Body and axis, are respectively arranged with opposite installation via in babinet two opposite side walls, and the axis sequentially passes through the installation via
It is connect with the babinet, it is characterised in that：Sealing element is set between the inner wall and the axis of an installation via A wherein,
Sealing element is set between the outer and the axis of another installation via B.
In order to further increase sealing performance, it is equipped with annular groove on the inner wall of the installation via A, in the axis and institute
It states and is provided with sealing ring between annular groove.
To further increase sealing performance, the outer of the installation via B is provided with step holding tank inwardly, in institute
It states and is provided with sealing element in holding tank, locating part is additionally provided with outside the sealing element.
The sealing element being arranged in the holding tank is sealing ring.
The sealing ring being arranged in the holding tank is two.
The locating part is the washer and retainer ring for being set in the axis outer wall, and the retainer ring fixation is fastened on the axis.
The axis is clutch yoke axis, and the babinet is gearbox body.
A kind of mini-tiller, including axis mounting structure described above.
Advantageous effect：
1, the damage for avoiding sealing ring is solved using the axis mounting structure of the utility model and is not easy chamfering in babinet
The problem of, problem is damaged caused by avoiding sealing ring from directly being contacted with sharp edge, improves installation reliability, and reduce
The waste of sealing ring.
2, cost is reduced, cost is reduced and is embodied in two aspects, on the one hand to reduce the use of bushing, it is known that a lining
The cost of set is nearly 2 yuan, and the use for reducing two bushings saves nearly 4 yuan of cost, is on the other hand embodied in making for sealing ring
With using the mounting structure of the utility model, it is entirely avoided the damage of sealing ring.
3, sealing performance is improved, using the mounting structure of the utility model, sealing ring installation reliability is high, will not damage
Bad or recessive damage, so that good seal performance.
4, product qualification rate is improved, reduces the use of bushing, then reduces the installation that bushing occurs during the installation process
The problem of deviation, and then improve the qualification rate of product.
5, installation operation process is reduced, efficiency of assembling is improved.
