Rolling bearing manufacture processing is very convenient.
In above-mentioned rolling bearing, described flute profile is arranged on the middle part of bearing height.
In above-mentioned rolling bearing, described flute profile tooth root width is 0.5-0.8 times of bearing height.
In above-mentioned rolling bearing, the tooth root both sides of the flute profile form the first contact surface with bearing end respectively,
Two sides of teeth groove notch are respectively equipped with the second contact surface with the first contact surface matches mutually, when flute profile is ratcheting with teeth groove
Afterwards, the first above-mentioned contact surface mutually fits with the second contact surface.
In above-mentioned rolling bearing, described flute profile cross section contour is in sinusoidal.
In above-mentioned rolling bearing, arc angling is provided with the notch of described teeth groove.
In above-mentioned rolling bearing, described flute profile cross sectional shape is trapezoidal.
Compared with prior art, the advantage of this rolling bearing is：
1st, by provided with flute profile and the teeth groove and described flute profile part that match with flute profile stretch into teeth groove, install
Before, flute profile is partly stretched into teeth groove, so as to prevent the high infraversion malposition of flute profile and teeth groove during installation；
2nd, the part flute profile stretched into teeth groove has guide effect, virtually improves the installation effectiveness of bearing；
3rd, because flute profile end has the transition part that seamlessly transits, it is to avoid crush because of flute profile end, fall bits to damage bearing,
Virtually extend the service life of this rolling bearing.
4th, design more reasonable.

Embodiment
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
Embodiment one
As illustrated in figs. 1 and 2, the utility model provides a kind of rolling bearing, and the rolling bearing includes the axle in annular
Hold 1, a diameter of D and D=38mm of the bearing 1, the height of bearing 1 is H and H=4.5mm, and the thickness of bearing 1 is T and T=
1mm, therefore the ratio between diameter D and height H is 8.44.
This rolling bearing is sintered in the copper powder layer of thereon and is penetrated into and covered the anti-friction wear-resistant of copper powder layer by substrate
Plastic layer constitutes 3-layer composite material, and is made of rolling technology, the nature interface position shape of annular bearings 1 after rolling
Into the open seam 2 of axial direction together.The flute profile (3) that described open seam (2) one end is provided with and set along bearing (1) circumferencial direction,
The other end of open seam (2) is provided with the teeth groove (4) matched with the flute profile (3) and described flute profile (3) partly stretches into teeth groove
(4) in.
At present, for the big and thin rolling bearings of the ratio between D/H, using the open seam be arrangeding in parallel, open when mounted
The problems such as mouth seam closed end easily produces high infraversion malposition, contraposition is inaccurate, so as to influence the efficiency of the installation of bearing.In the present embodiment
In, by flute profile 3, the ratcheting setting of teeth groove 4 and in the state of free state is when bearing is unassembled, described flute profile 3 is
Stretched to through part in teeth groove 4, so that the high infraversion malposition of the closed end of open seam 2 during installation is prevented, and the portion stretched into teeth groove 4
Divide flute profile 3 that there is guide effect, virtually improve the installation effectiveness of this rolling bearing.
In the present embodiment, the end of flute profile 3 has the transition part 31 seamlessly transitted, and the cell wall of teeth groove 4 is also smoothly to set
Put.The setting of this kind of structure avoids crushing bits because of flute profile end insufficient strength to damage bearing, virtually extends this volume
The service life of bearing processed.
As shown in figure 3, as the prioritization scheme of the present embodiment, described flute profile has the cross section profile of one and flute profile 3
