Abstract

ABSTRACT OF THE DISCLOSURE

A taper split sleeve is inserted between an axle and a wheel to fix the wheel to the axle by the taper portion of the split sleeve.

Description

~1~86~9 The present invention relates to a r,lounting wheel structure, SUC}l as a tire wheel, lug wheel or crawler wheel.
As a method of mounting a wheel to an axle, clamping by bolts and nuts or the use of a key has generally been known.
Such conventional mounting methods not only require a long time, but also do not permit the fixing of a wileel at a desired position on an axle.
The present invention provides a wheel mounting device by which a wheel may readily ~e fixed to an axle at a desired position thereof, thereby to readily change the wheel thread.
According to the present invention there is provided a wheel mounting structure comprisiny; a wheel having a disk which is formed to integrally define in a central position thereof a hub portion with a tapered inner surface, an axle extending ;~
through said hub portion and having a plain outer surface, a split sleeve disposed between said hub portion and said axle, said split sleeve having a tapered portion substantially corres-ponding to said tapered inner surface of said hub portion and a threaded portion at a small diameter end thereof, said split sleeve having a plain inner surface substantially corresponding to said plain outer surface of said axle, said tapered portion of said split sleeve having at least one axial split groove to permit variation in an outer diameter thereof, said split groove being defined in said tapered portion but not extending to said threaded portion, and a nut adapted to engage said threaded portion of said split sleeve and to abut against part of said wheel whereby said wheel is fixed at a desired position on said axle immovably in axial and peripheral directions of said axle only by wedging action of said split sleeve caused by tightening o said nut under normal condition, and said split sleeve and axle serve as torque limiter by slipping with respect to each other when an excessive torque acts on said wheel.

Suitably the hub portion of said disk is provided at an end thereof with a ring element to be abutted against by said nut.
In particular a further nut is desirably adapted to engage a threaded portion formed on an outer periphery of said ring element for contacting said nut and said wheel is drawn toward the small diameter end of said split sleeve by tightening of said further nut which removes the wedging action of said split sleeve and frees said wheel from a fixed state.
10Desirably the stopper means is provided on said axle to prevent removal of said split sleeve from said axle.
The present invention will be further described by way of example with reference to the accompanying drawings, in which:
Fig. 1 is a longitudinal sectional view of a wheel mounting device in accordance with one embodiment of the present invention;
Fig. 2 is a sectional view of the main portions in Fig. l;
Fig. 3 is a perspective view of a split sleeve;
20Fig. 4 is a sectional view of a sleeve removing structure, and . c., ;,, - la -` ` 9L~¢~136Ç;~
!
Fig. 5 is a sectional view of a wheel mounting device in accordance with another embodiment of the present invention.
Fig. 1 illustrates a state in which a wheel 4 is inte-grally fixed by means of a disc 4c and hub 4a to a drive axle
2 extending from a transmission case, and the ghost line 3 shows another state in which the wheel 4 is mounted on the axle at a different position.
A split sleeve 5 is provided with a taper portion 5a, the outer diameter of which may be changed. The taper portion 5a is provided at the outer surface of the small diameter portion thereof with a threaded portion 5b, and at the main body thereof with a plurality of axial split grooves a which are open at the ~-large diameter end of the taper portion 5a, thereby to permit change of the diameter of the taper portion 5a. From the large diameter portion, this split sleeve 5 is slidably inserted into the axle 2 with a predetermined dimensional tolerance.
- A hub 4a of the wheel 4 has an internal shape which corresponds approximately to the external shape of the taper portion 5a. A nut 7 is threadedly connected to the threaded portion 5b through a washer 6 disposed between the nut 7 and aring element 4d or the hub 4a. Thus, by this clamping means A
constituted by the nut 7 and the threaded portion 5b, the wheel 4 is pressed toward the large diameter portion of the split sleeve 5. The axle 2, the split sleeve 5 and the wheel 4 are therefore integrally fixed to each other. Namely, by the wedging action of the taper portion 5a of the split sleeve 5 inserted between the axle 2 and the wheel 4, the three com-ponents, 2, 4 and 5 are integrally fixed to each other, thus providing a simple, easy and assured mounting of the wheel 4 on the axle 2 in a stable condition.
In addition, the tread of a wheel may readily be changed by moving the split sleeve 5 axially of the axle 2 as necessary.

~ .

36~9 According to the present wheel mounting device, adjust-ment of clamping pressure by the clamping means A may cause s lip - 2a -~86~g ~_tween the axle 2 and the split sleeve 5, or between the wheel 4 and the spllt sleeve 5, thus serving as a torque limit structure for preventing damage to gears in the power drive system, for ex-ample, in the case excess load has been applied to tlle wheel 4.
At this time, a member 8 disposed at the axle ~nd for preventing the split sleeve 5 from coming off unexpectedly from the axle 2 is efficiently operated as best shown in Fig. 2.
~hen intending to release the wedye action of the split sleeve 5, it is enough to strike the split sleeve 5 toward the large diameter portion thereof or the wheel 4 toward the small diameter portion of the split sleeve 5, after the nut 7 has been removed. Alternatively, as shown in Fig. 4 a threaded portion 4b may be forMed at the outer surface of the end of the hub 4a, and a nut 9 to be threadedly connected to this threaded portion 4b may be formed at the small diameter end of the split sleeve 5 so as to contact therewith, whereby the split sleeve 5 may be pressed out by clamping action of this nut 9. In this case, the nut 9 May be contacted with the end surface of the nut 7, so that the split sleeve 5 is pressed out without removing the nut 7.
In Fig. 5 illustrating another cmbodiment oE the wheel mounting device in accordance with the preserlt invention, the por-tion 5a of the split sleeve 5 is tapered toward the axle insertion side thereof, and the nut 7 of the clamping means A is adapted to threadedly connect to the wheel 4, whereby the axle 2, the split sleeve 5 and the wheel 4 are integrally fixed by clamping pressure caused by drawing action of the clamping means A.
It is to he understood that the axle 2 of circular, square or hexagonal section may be used, and the structure of the clamping means A may be modified in various ways. In addition, the present invention may be applied to different type wheel struc-tures including lug wheels of a rice-planting machine or crawler wheels of a crawler travelling machine. In the par-ticular case of ~6)86~9 .awler wheels, it is advantageous to adopt the torque limit structure as described earlier. It is also a matter of course that the present invention may be applied to machines other than agricultural machines. Furthermore, a spli-t sleeve having a C-shape section which is axially split at one portion thereof, may also be used.
