A trailer ball bearing turntable is a part installed on a trailer to connect a tractor/trailer/truck so that it can realize the turning function while transferring the traction force from the tractor.
What are the installation steps for trailer ball bearing turntable?
How do I lubricate the ball bearing slewing ring of the trailer?
How to adjust the gear clearance of the trailer ball bearing turntable?
Before installing the trailer ball bearing slewing ring, the mounting surface of the main motor should first be checked. It is necessary that the support has sufficient strength, the connecting surface machined, and the surface is smooth and free of deposits and burrs. For those who cannot be machined to achieve the required flatness, special plastics with high splash strength can be used as fillers to ensure the accuracy of the installation plane and reduce vibration.
The clamp of the trailer ball bearing turntable has a quenched soft band area marked "S" on the end face of the clamp.When installing, the position of the soft belt should be placed in the non-load area or the non-normal load area (the dowel hole is always on the soft belt).
When installing the ball bearing turntable of the trailer, first perform radial positioning, cross-tighten the mounting screws and check the rotation of the bearing. When tightening the screw, there should be sufficient preload force, and the preload force should be 70% of the yield strength of the screw material. Fastening screws should be equipped with tempered flat washers, and spring washers are strictly prohibited.
1. Track lubrication
To ensure sufficient lubrication, before first use, the trailer ball bearing slewing ring should be the one shown in the drawing or refill the fat specified in the product manual. Pay special attention to all grease nipples one after the other, preferably while rotating the ball bearing turntable of the trailer until you see that the grease is leaking.
2. Gear lubrication
When the gears are lubricated, the tooth surfaces should be clean. It is recommended to use a clean brush to apply grease to the gears.
When installing a toothed trailer ball bearing turntable, it is important to adjust the gear play correctly. It can be adjusted with a probe gauge at the highest point of the concentricity of the gear or by pressing in a lead wire or other suitable methods. If the backlash is not within the specified value, the pinion can be moved to change the axle distance. After adjusting, rotate the turntable bearing at least one full turn to ensure that no other teeth jump beyond the peaks, and check the wrong play again after the turntable bearing is finally fixed. The highest point of the gear stroke is marked in green color in the groove.
