The inwall of shell is provided with the slot rolling matched with 3 road raceway；Also include being provided with steel ball in 3 retainers, the retainer.
The utility model is done further preferably, provided with the through hole communicated between the slot rolling.
The utility model is done further preferably, the bottom of the raceway is provided with the dovetail groove set along raceway bottom wall.
The utility model is done further preferably, the elliptical bearing shell is provided with the oilhole communicated with slot rolling, described
Oilhole carries rubber stopper.
The utility model is done further preferably, the end-play of the cartridge housing and bearing core is 0.15-0.2mm.
The utility model is done further preferably, the angle of the axis of the swing rod and the RADIAL of the bearing core is
10-15 degree.
The utility model is done further preferably, in addition to dust-proof seal ring.
The utility model is done further preferably, the dust-proof seal ring is arranged in the outside of outermost retainer.
The beneficial effect that the utility model is reached compared with prior art is：
The utility model is in the outer wall 3 road raceways of formation of the bearing core, and the inwall of the cartridge housing is provided with and described 3
The slot rolling that road raceway matches；Also include being provided with steel ball in 3 retainers, the retainer.The utility model is set using 3 row's steel balls
Put, improve the power that can bear during use, and the power born is uniformly distributed, and extends overall service life.
Single-row steel ball is set so that during actual electric drill use, impulsive force, which is spent, causes greatly biased, discontinuity, and this reality
Set with new three road steel ball so that the power born is uniform, and service life is greatly improved.
From the foregoing, it will be observed that the utility model can solve the problem that the shortcomings of the prior art, institute during use is improved
The power that can be born, and the power born are uniformly distributed, and extend overall service life.
Brief description of the drawings
Accompanying drawing is used for providing further understanding to of the present utility model, and constitutes a part for specification, with this practicality
New embodiment is used to explain the utility model together, does not constitute to limitation of the present utility model.
In the accompanying drawings：
