For setting the ball limiting slot of ball.Bearing directlys adopt centreless design and greatly reduces production cost.
Preferably, further including that lid is located at the flange outer ring other side for limiting the ring washer of ball.It is solid using retaining ring
Determine ball, lid is located at bearing side, prevent gas shock directly impact in bearing to take away greasing substance.
Preferably, side through hole edge is equipped with flange collar in the retaining ring, the flange collar section is triangular in shape, side wall and through-hole
Inner wall is consistent, and angle is formed between flange collar and retaining ring, plays certain guiding function to air-flow, prevents the direct contact bearing rolling of air-flow
Pearl prevents greasing substance to be entrained by the flow of air.
Preferably, the raceway outer is equipped with chamfering, the raceway outer after the retaining ring lid is located on flange outer ring
Chamfering and retaining ring form the angle gap being detained for lubricating fluid.
Preferably, being equipped with the chimb for setting up O-ring on the outside of the flange outer ring, the chimb is with side angle
It is arc-shaped.Chimb and the arc-shaped angle in side can be convenient O-ring setting on the outside of flange outer ring, greatly facilitate in bearing group
The control of dress process intermediate gap.
Preferably, improving ball degree of lubrication, ball limiting slot side offers oil storage tank on the retainer.
Preferably, being equipped with the holding tank for accommodating retainer on the inside of the flange outer ring.
Preferably, the retaining ring outer extends the convex edge being equipped with for wrapping up bearing.
Preferably, the flange outer ring is made of outer ring and housing, the raceway is arranged in the outer ring inner wall, institute
Stating coat part includes confined planes, is wrapped in outer ring sidewall sections and chimb.
Further, the retaining ring face ball is equipped with groove, and the groove is arranged concentrically with retaining ring.The groove also can be used
Greasing substance is received in storage.
Can be set up directly on shell when in use also can be by O-ring sandwiched inside the shell, then only need to be by pneumatic whirlpool
Taking turns bearings at both ends insertion middle part can be used.
The utility model has the beneficial effects that: 1: the cost of bearing is greatly reduced, to reduce air impeller
The cost of machine；2: avoiding air-flow during operation and take away greasing substance to influence bearing service life；3: using method
It is easy for installation while reducing noise that the design of blue outer ring is arranged O-ring；Reduce the diameter jump during bearing operation.
