Description
Technical field
The utility model belongs to a kind of field of bearings, and in particular to a kind of combination bearing.
Background technique
Bearing (Bearing) is a kind of important spare part in contemporary mechanical equipment.Its major function is the mechanical rotation of support
Swivel, reduces the coefficient of friction in its motion process, and guarantee its rotating accuracy.According to the difference of the friction properties of the moving elements, axis
Rolling bearing and sliding bearing two major classes can be divided by holding.Wherein rolling bearing is normalized, seriation, but with sliding bearing phase
More larger than its radial dimension, vibration and noise, price is also higher.Rolling bearing is generally by outer ring, inner ring, rolling element and holding
Four part of frame composition.By the shape of rolling element, rolling bearing is divided into ball bearing and roller bearing two major classes.
Generally all shaft is all interference fit to traditional bearing, it is therefore desirable in view of the production precision of shaft, if turned
The outer diameter of axis is too big, and bearing may be made not easy to install, if the outer diameter of shaft is too small, causes gap between bearing and shaft excessive
And it loosens.
Utility model content
(1) technical problems to be solved
The technical problems to be solved in the utility model is the production precision of shaft or shaft to be reduced.
(2) technical solution
A kind of in order to solve the above technical problems, the technical scheme adopted by the utility model is: combination bearing, including it is interior
Circle, outer ring, the first roller, thread bush and multiple card keys；The periphery of the inner ring is socketed with the first roller and thread bush, institute
The periphery of the inner ring and inner ring of stating the first roller is coaxially connected, and outer ring is coaxially connected with outer ring；The periphery of the inner ring is set
It is equipped with the uniformly distributed sliding groove of multiple annulars, the inner ring and outer rings of inner ring are connected to by the sliding groove, and the bottom of card key is plugged on cunning
In dynamic slot, top is provided with an inclined-plane, and the thread bush is threadedly coupled with inner ring, and the thread bush includes inner hole, described
The hole wall and contact of incline plane of inner hole.
Further include the second roller and ring support in combinations of the above bearing, the axial sides of second roller respectively with circle
Seat and inner ring rotation connection.
In combinations of the above bearing, including the outside of the second roller is arranged in retainer, the retainer.
In combinations of the above bearing, the card key has 4.
It further include retainer ring in combinations of the above bearing, the inner headed face of the outer ring is provided with an annular groove, the retainer ring
Clamping is in a ring groove.
(3) beneficial effect
The uniformly distributed sliding groove of multiple annulars is arranged in the combination bearing of the utility model, is provided with and turns in the sliding groove
It is mobile simultaneously and rotating axis locking towards rotor shaft direction to control card key by the moving in rotation of thread bush axial direction for the card key of axis contact, because
This connection is stronger.So there is no need to limit brearing bore perhaps the precision of spindle outer diameter therefore can reduce brearing bore or
The precision of spindle outer diameter makes more convenient.
Detailed description of the invention
Fig. 1 is the schematic diagram of internal structure of the combination bearing of the utility model；
Fig. 2 is the enlarged drawing of A in Fig. 1；
1 it is inner ring in figure, 2 be outer ring, 3 be the first roller, 4 be thread bush, 5 be card key, 6 be sliding groove, 7 is inclined-plane, 8
It is ring support for the second roller, 9,10 be retainer, 11 be annular groove, 12 is retainer ring.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
Embodiment: a kind of combination bearing as depicted in figs. 1 and 2, including inner ring 1, outer ring 2, the first roller 3, thread bush 4
With 4 card keys 5；The periphery of the inner ring 1 is socketed with the first roller 3 and thread bush 4, the inner ring of first roller 3 with
The periphery of inner ring 1 is coaxially connected, and outer ring and outer ring 2 are coaxially connected；It is uniformly distributed that the periphery of the inner ring 1 is provided with multiple annulars
Sliding groove 6, the inner ring and outer rings of inner ring are connected to by the sliding groove 6, and the bottom of card key 5 is plugged in sliding groove 6, and top is set
It is equipped with an inclined-plane 7, the thread bush 4 is threadedly coupled with inner ring 1, and the thread bush 4 includes inner hole, the hole wall of the inner hole
It is contacted with inclined-plane 7.
This structure further includes the second roller 8 and ring support 9, the axial sides of second roller 8 respectively with ring support 9 and inner ring
1 rotation connection.
This structure further includes retainer 10, and the outside of the second roller 8 is arranged in the retainer 10.
This structure further includes retainer ring 12, and the inner headed face of the outer ring 2 is provided with an annular groove 11, and the retainer ring 12 is clamped
In annular groove 11.
When installation, first inner ring 1 is socketed on shaft (in figure for show), then 4 axial-rotation of thread bush so as to
It moving axially, the inner hole in the thread bush 4 touches the inclined-plane 7 of card key to make card key block shaft, therefore completes connection,
Connect it is very secured, so there is no need to limit brearing bore perhaps the precision of spindle outer diameter therefore can reduce brearing bore or turn
The precision of axis outer diameter makes more convenient.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvements and modifications can also be made, these change
It also should be regarded as the protection scope of the utility model into retouching.
