Description

Bearing support structure

Technical field

The present invention relates to a kind of supporting structure, refer to a kind of institute's spring bearing supporting structure in working life that improves especially.

Background technique

Bearing is in the mechanical structure, and the common auxiliary component of being located between two rotating elements rotates smooth and easyly in order to make between the rotating element, reduces mechanical loss.

Wherein, have axis hole and supply the structural cover of bearing installing to be called bearing support structure, and when bearing is arranged in the bearing support structure now; This bearing causes the bearing shell because of axially going up the unbalance stress slight inclination from axial stress, more can further need bear the compressing of radial stress; Cause the ball in the bearing to receive very big extruding; Gently then cause bearing operation to have some setbacks, heavy then when bearing high speed rotating and stress are excessive, the anxiety of the deformed element of causing, impaired or damage is arranged.

In view of this, how improve, and then guarantee that shaft strength rotates equably, naturally this people in the industry direction of demanding urgently making great efforts to bearing support structure.

Summary of the invention

The objective of the invention is to improve the deficiency of existing technology, a kind of bearing support structure that improves working life is provided.

For realizing above-mentioned purpose, the present invention adopts following technological scheme:

One annular inner wall, this inwall enclose the axis hole that structure one supplies bearing to be provided with, and on this annular inner wall, offer an annular shallow ridges.

Said shallow ridges position in the axial direction is corresponding with those roll pieces.

Said shallow ridges extended length in the axial direction is more than or equal to those roll pieces length in the axial direction.

Definition has one first support surface and one second support surface on the said inwall, and this first, second support surface lays respectively at this shallow ridges both sides.

Said shallow ridges position in the axial direction is corresponding with those roll pieces, makes this first, second support surface lay respectively at those roll pieces both sides in the axial direction.

Said shallow ridges has one first ora terminalis and one second ora terminalis, and this first ora terminalis is close to said first support surface, and this second ora terminalis is close to said second support surface, and this first, second ora terminalis and the central axial distance of each said roll piece are isometric.

Also or, said shallow ridges has one first ora terminalis and one second ora terminalis, this first ora terminalis is close to said first support surface, this second ora terminalis is close to said second support surface, construction one furrow bank between first ora terminalis to the second ora terminalis wherein, this furrow bank is an inclined-plane.

Again or, said shallow ridges has one first ora terminalis and one second ora terminalis, this first ora terminalis is close to said first support surface, this second ora terminalis is close to said second support surface, construction one furrow bank between first ora terminalis to the second ora terminalis wherein, this furrow bank is a circular arc camber.

Described bearing support structure comprises that also one rotates auxiliary member, and it is to be arranged in the said inner casing, and the outer ring surface of this rotation auxiliary member is to supply to lean with the inner ring surface of bearing.

Be formed with a groove on the outer ring surface of said rotation auxiliary member.

Beneficial effect of the present invention is: improve working life, reduce mechanical loss, improve working stability.

Through accompanying drawing the present invention is described further below.

Embodiment

Below will the effect that structure characteristic of the present invention and expection thereof are reached be described, but be not in order to limit claim protection domain of the present invention, to chat bright in advance through preferred embodiment.

Please refer to Fig. 1 to Fig. 6.In the present invention's one preferred embodiment, this bearing support structure 1 supplies to support a bearing 2, and this bearing 2 has a shell 3, an inner casing 4 and a plurality of roll piece 5, and those roll pieces 5 for example are glomerate balls, thereby is able to make the inside and outside shell can a relative rotational.Wherein, this bearing support structure 1 lid has an annular inner wall 10, and this annular inner wall 10 encloses the axis hole 11 that structure one supplies bearing 2 to be provided with, and on this annular inner wall 10, offers an annular shallow ridges 12.

Wherein, this shallow ridges 12 position in the axial direction is corresponding with those roll pieces 5, and this shallow ridges 12 extended length in the axial direction is not less than those roll pieces 5 length in the axial direction, and so-calledly axially promptly refers to the direction parallel with this axis hole bearing of trend.In addition; Definition has one first support surface 13 and one second support surface 14 on this inwall 10; This first,

second support surface

13,14 lays respectively at this shallow ridges 12 both sides; This first,

second support surface

13,14 lays respectively at those roll piece 5 both sides in the axial direction, and this shallow ridges 12 has one first ora terminalis 121 and one second ora terminalis 122 again, these first ora terminalis, 121 these first support surfaces 13 of next-door neighbour; This second support surface 14 of 122 of this second ora terminalis next-door neighbour, this first, second ora terminalis 121,122 equates with these roll piece 5 central axial distances respectively.

In addition; See also among Fig. 5 A the present invention shallow ridges 12 in 122 construction of first ora terminalis, 121 to second ora terminalis, one furrow bank 123; This furrow bank 123 can be an inclined-plane, and wherein this furrow bank 123 extends to a ramp structure by first ora terminalis 121 and second ora terminalis 122 to the centre of two ora terminalis; 123 of furrow banks can be the arc-shaped surface structure among another embodiment in Fig. 5 B; Another embodiment then is arranged with one and rotates auxiliary member 6 outside the inner casing 4 of this bearing 2 in Fig. 5 C in addition; It is to be arranged in this inner casing 4, this rotation auxiliary member 6 can be one have a ring pipe portion axostylus axostyle, in order to bearing 2 mutual starts; Wherein the outer ring surface of this rotation auxiliary member 6 is to supply to lean with the inner ring surface of bearing 2; And on the outer ring surface of this ring pipe portion relatively the roll piece 5 of bearing 2 be formed with a groove 61, when this groove can make this bearing 2 of outer ring surface contact, make that bearing 2 shells are stressed evenly to be difficult for tilting; And the ball in the bearing 2 can not receive external force pressure, and it is smooth and easy to make bearing 2 rotate.

Thereby; This first, second support surface can be resisted against top, the position, bottom of this shell respectively, makes this shell radially force in roll piece and difficult inclination, and the ball in the bearing can not receive external force pressure; Can guarantee that so bearing rotation cunning is suitable, avoid fault; Except the mechanical loss that can reduce bearing structure, more can prolong bearing working life in view of the above, have progressive effect really.

Bearing support structure according to the invention is that general reference has axis hole and can supply the mechanical structure of bearing setting; What for example Fig. 1 was extremely shown in Figure 6 is to supply the sheathed bicycle element of bicycle crank; As Fig. 7 with shown in Figure 8 then be two kinds of aspects that bicycle hub cooperates with bearing; The bearing support structure that right the present invention is alleged is also not only exceeded with what embodiment illustrated, chats bright in advance.
