## ” axle of Daye ” -The angle contacts the structure type of the ball bearing

30th June 2010 Bearing Technology 0 Comments

Horn it exposed to the intersection of ball bearing and terminal rotational speeds to be relatively high, can bear the intersection of radial and load and axial load at the same time, can also bear the purely axial load. It is determined by the fact that exposed to the angle that it bears axially loaded ability, and is exposed to the angle to increase and increase at the same time.

Structural pattern
1. The separating angle contacts the ball bearing
Inner circle and outer lane of such structural bearing can’t separate installation, there is a structural pattern of the following aspects specifically:
Contact the angle α=15 degrees, it is the 7000C type to lock the mouth in the outer lane
Contact the angle α=25 degrees, it is the 7000AC type to lock the mouth in the outer lane
Contact the angle α=40 degrees, it is the 7000B type to lock the mouth in the outer lane

2. Contact the ball bearing at four o’clock
Such structural bearing, in order to separate the bearing. Among them, QJ000 type have pairs of half inner circle, QJF000 type have pairs of half an outer lane, it is 35 degrees to be exposed to the angle. While there is no load and pure radial load to act on, the steel ball keeps in touch with one set of circles at four o’clock. Under the pure loaded function axially, the steel ball keeps in touch with one set of circles for two o’clock. Can bear the two-way axial load, can also bear the moment load.

3. Pair lists the angle and contacts the ball bearing
Such structural bearing can bear the larger radial, axial two-way union load and moment load relying mainly on radial load. It can limit the axle or two-way axial displacement of outer cover, contact the angle as 30 degrees or 40 degrees .

Keep a material
The angle contacts the ball bearing and generally adopts the stencil plate to press and keep the shelf or brass entity keeping the shelf. Pair list horn, contact ball bearing, adopt the brass entity, keep the shelf generally.

Allow the angle of inclination
What the angle is contacted in the ball bearing, between the outer lanes is tiltable and limited, allow the angle of inclination to depend on operating in the interval, bearing size, inside design within the bearing and act on strength and moment on the bearing, allow the angle of inclination to guarantee to produce the too high extra stress in the bearing the most largely.
If inner, store in the angle of inclination between the outer lanes will influence the bearing life-span. Meanwhile, the bearing operates the precision to drop, the noise of operating increases.
