How to adjust the taper roller auto bearing?

The inner and outer rings and rolling elements of the taper roller auto bearing are tapered, and the inner and outer rings can be separated. Its characteristic is that the bearing clearance can be adjusted, the bearing capacity is relatively large, and it can bear radial force and axial force at the same time.

How to adjust the axial clearance of taper roller auto bearing?

For installing taper roller auto bearings, the thrust clearance can be adjusted by adjusting the nut on the journal, adjusting the washer and bearing seat thread or with a preloaded spring. Axial clearance is the bearing dimension when mounted. In this arrangement, the distance between the bearing, shaft and bearing can be determined according to the operating conditions. When adjusting the clearance for high load, the high-speed taper roller auto bearing must adjust the effect of temperature rise on the axial clearance. For low-speed and vibrating bearings, backlash-free or pre-assembled installations should be used. The purpose is to make the roller and raceway of taper roller auto bearing produce good contact load and evenly distribute, and prevent the drum and drum from being damaged by vibration. Check the size of the adjustment axial clearance with a dial gauge. The method is to attach the first micrometer to the body or housing with the glossy surface of the micrometer contacting the shaft against the shaft. The maximum allowable amount of the axial pin is the axial clearance value.

How does the taper roller auto bearing perform commissioning and temperature detection?

In order to make the rollers of the taper roller auto bearing have good contact with the raceways and obtain a suitable axial clearance, the sub-bearings should be tested and tested after each adjustment of the clearance. The method is to first operate at low speed for 2-8 minutes, then speed test for 2 hours, and then step by step to high speed. The test run at each speed shall not be less than 30 minutes and the heating rate shall not exceed 5°C/hour and the final stable temperature shall not exceed 70°C. In addition, care should also be taken when installing and adjusting taper roller auto bearings.

Does the position of the action point of the taper roller auto bearing on the shaft matter?

The action point is mainly to consider the impact on the shafting stiffness after the entire bearing is installed, because the bearing action point can change with the direction of the bearing installation. Therefore, when calculating the bearing life and the overall stiffness, the position of the bearing point of action should be considered. In bearings with a contact angle of 0° to 90°, the point where the line connecting the contact points between the rolling elements and the inner and outer ring raceways (the line representing the contact angle) intersects the central axis of the bearing. In taper roller auto bearings, it is the point at which the center of the contact length at the outer ring intersects the longitudinal line of the outer ring raceway surface and the bearing center axis.

To meet these growing demands, Shandong Xuanye Precision Machinery Co., Ltd. has committed to providing the increasing of taper roller auto bearings, and make them more effective, reliable, and consistent.
