What are the installation steps for trailer ball bearing turntable?
Generally, the trailer ball bearing turntable adopts the total hardened carbon chrome bearing steel. The grade is GCr15 or GCr15SiMn steel; The ferrule of the trailer ball bearing turntable is made of surface hardened steel. If the user has no special requirements, it is generally made of 50Mn steel, but sometimes to meet the host's requirements in some special applications. The specific terms of use provided by the user choose other grades of surface hardened steel, such as 42CrMo, 5CrMnMo, etc.
The diameter of the center circle of the rolling element is 3150 mm, the diameter of the ball 75 mm, the gear module m H220 mm, the ring material 50 Mn and the raw material the normalized state.
The seal of the trailer ball bearing turntable is designed to prevent the filled grease from escaping and, on the other hand, to prevent dust, impurities and water from entering the interior of the bearing from the outside, affecting normal operation. Since the trailer ball bearing turntable usually works under high load and low speed, the bearing seal type uses two structures, a rubber seal ring and a labyrinth seal. The rubber seal structure itself has the advantages of simple structure, small occupied space and reliable sealing performance, and has been widely used. Labyrinth seals should be used for large roller bearings operated under working conditions.
1. Dimensions
The diameter is usually 0.4 cm to 10 m, up to 40 m.
2. High load capacity
Generally, it can accommodate axial load, radial load and tilting moment load together.
3. Low speed
The working speed is lower than 10/min, and in some cases it does not rotate successively, but only rotates within a certain angle and makes a swivel movement.
4. With bearing seat slot
It can be fastened with screws to the upper and lower supports.
5. No pivot point
The inner ring or outer ring has gears for the rotary drive.
6. With lubricating oil bore and sealing installation.
The main structural methods of trailer ball bearing turntable are characterized as follows: four-point contact ball turntable bearing seat, two-row angular contact ball turntable bearing seat, interspersed cylindrical roller turntable bearing seat, interspersed taper roller turntable bearing seat, three-row cylindrical roller bearing seat Customize the large roller bearing seat.
