THRUST BALL BEARINGS
May 19th, 2008 | by admin |☆ creation characteristics
Thrust ball bearings from the dig laps, Seat, Ball and Cage composition, with the axis harmonious Rings titled axis laps, with the bomb harmonious Rings titled seat, centre artefact spherical The bearings are aligning performance, crapper turn the effect of the artefact error.
Thrust ball bearings to bear the important stem load, crapper designate super stem load, but crapper not give symmetric load. Such bearings are mainly utilised in automobile control mechanism, much as organisation spindle.
★ Product Categories
ZWZ creation of oblige ball bearings crapper be generally categorised into digit types:
1. Thrust ball bearings one-way
2. Bi-directional oblige ball bearings
One-way oblige ball bearings
Including an axis circle, a centre and the ball - Cage components. Bearing clastic dig laps, Seat, Ball - Cage removed components crapper be installed. Can be separated into threesome types:
1. Plane Seat track oblige ball bearings
2. Aligning centre track oblige ball bearings
3. Aligning centre track and aligning ball bearing oblige washers Block
One-way important oblige ball bearings to resist a one-way stem load, and crapper be single-axial direction of the location.
Two-way oblige ball bearings
Including an axis lap, digit laps Block, a lot and the ball dig - Cage components. Bearing clastic dig laps, Seat, Ball - Cage removed components crapper be installed. Can be separated into threesome types:
1. Plane Seat track oblige ball bearings
2. Aligning centre track oblige ball bearings
3. Aligning centre track and aligning ball bearing oblige washers Block
Two-way oblige ball bearings bearing inexpensive two-way stem load, and two-way stem location.
Size range, 2000
ZWZ the base oblige ball bearings sizes are traded in the table,
Size arrange diameter: 25 mm ~ 1380mm
Size arrange diameter: 42 mm ~ 1540mm
Size arrange width: 11 mm ~ 160 mm
● Tolerance
ZWZ accepted with the generalized oblige ball bearings level, P6, P5, P4-level quality levels, in distinction with domestic standards.
◇ Cage
Cage the generalized stamping planes, the two-entity structure, where primary requirements haw also hit another cage.
When the bearings D ≤ 250 mm diameter, a bag (with) stamping Cage, Cage’s bag after the cipher did not sign.
When bearing diam D> 250mm, a monument entities Cage, Cage’s bag after the cipher does not sign, and the remaining signs the same place code.
◆ peak stem load
Thrust ball is in operation, if added alluviation is likewise small, not high axial, motorial obligate cod to the role, Ball module hit a bearing artefact and alteration the connatural functioning. To preclude this from happening, oblige ball bearings in their effect staleness bill the peak stem loading. Famin.
Famin = 5.1 ()
Of which: Famin: the required peak load??? [KN]
n: to r / min
C0a: base rated noise alluviation [KN]
Allow point of error
Thrust ball bearings activity the digit staleness grappling parallel, does not earmark some deviation. Spherical centre and spherical washers with the oblige ball bearings for mental, crapper turn the artefact point of the effect of error.
□ equal impulsive load
P = Fa [KN]
■ equal noise load
P0 = Fa [KN]
