Thrust tapered roller bearings can accept one-way axial loads.
The type of thrust tapered roller bearing is coded as 90000.
Because the output of thrust tapered roller bearings is small; the types produced by various factories are mostly non-standard shape scales; the series with standard shape scales; the types of production are less; therefore, there is no national standard specification for the shape scale of such bearings.
Second, the thrust angle touch ball bearing layout, function features thrust angle touch ball bearing touch angle is usually 60 ° commonly used thrust angle touch ball bearings are usually two-way thrust angle touch ball bearings; first used for fine machine tool spindle; usually with double column Cylindrical roller bearings work together; can accept two-way axial load; with high precision; good rigidity; low temperature rise; high speed; easy to assemble and disassemble.
Third, the double row tapered roller bearing layout, functional characteristics Double row tapered roller bearing layout is complicated; the largest amount is 35000 type; there is a double raceway outer ring and two inner rings; there is a spacer between the two inner rings; Change the thickness of the spacer to adjust the clearance. These bearings can accept the biaxial axial load together with the radial load; the axial displacement of the shaft and the outer casing can be constrained within the axial clearance of the bearing.
Fourth, the layout of the tapered roller bearing features tapered roller bearing type code is 30000; tapered roller bearing is a separate bearing. Under normal circumstances; especially in GB/T307. 1-94 "rolling bearing radial bearing public service In the scale scale involved in the scale, the outer ring of the tapered roller bearing and the inner component are 100% universally interchangeable. The outer ring's viewpoint and the outer race diameter scale have been standardized as the outer dimensions. It is allowed to change during the drawing process so that the outer ring of the tapered roller bearing and the inner component can be universally exchanged on an international scale.
Tapered roller bearings are mainly used to accept radial and axial combined loads based on radial loads. Compared with angular contact ball bearings, the bearing capacity is large; the limit speed is low. Tapered roller bearings can accept axial loads in one direction. Can constrain the axial displacement of the shaft or housing in one direction.
5. Characteristics of deep groove ball bearings In the layout, each ferrule of deep groove ball bearings has one-third of the continuous groove type raceways whose cross-section is approximately the length of the equatorial circumference of the ball. Deep groove ball bearings are mainly used for Accepts radial loads; also accepts a certain axial load. When the radial clearance of the bearing increases; has the property of angular touch ball bearings; can accept axial loads alternating in two directions. Others with the same scale Type bearing comparison; friction coefficient of this type of bearing. 俑撸痪 俑撸痪 撸 撸 怯 ⌒ ⌒ ⌒ 〉 〉 〉 〉 〉 〉 〉 〉 〉 〉 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深A type of bearing.
