Shock absorber bearing with installation points

Shock absorber bearing equipment should be cleaned before, after monotonous use, and ensure excellent lubrication, bearings generally choose grease lubrication, can also choose oil lubrication. When selecting grease lubrication, grease with superior performance such as no impurities, anti-oxidation, anti-rust and extreme pressure should be selected. The filling amount of grease is 30%-60% of the volume of bearings and bearing boxes, and should not be too much. The bearing of the shock absorber with a sealed structure has been filled with grease and can be used directly by the user and cannot be cleaned.

When the interference is large, oil bath heating or sensor heating bearing method can be used to equipment, heating temperature scale of 80℃-100℃, the maximum can not exceed 129℃. At the same time, use nuts or other appropriate methods to tighten the bearing to avoid shortening the width direction of the bearing after cooling, so that there is an open space between the ring and the shaft shoulder.

Shock absorber bearing

The following four points should be paid attention to when shock absorber bearing collaboration equipment:

(1) It is necessary to pay attention to making bearing equipment and disassembly simple, saving labor, time and expense.

(2) The free end bearing must be able to adapt to the length change of the shaft and bearing seat hole, that is, it is necessary to have the ability to adapt to the axial position and move within a certain scale.

(3) The ring cannot slide in the tangential direction in its cooperative surface, otherwise it will damage the cooperative surface.

(4) The circumference of the bearing ring should have excellent support and uniform force to reduce deformation and give full play to the bearing capacity.

Pressure mounting method of shock absorber bearing inner ring

1. Measurement and adjustment of radial clearance In order to ensure that the radial clearance reserved for the inner ring, roller and shaft diameter thermal expansion of the running middle bearing is not too large or too small, and to avoid the change of equipment clearance in the later period, the following measurements should be taken carefully. When the equipment clearance is not reached, the equipment clearance is gradually adjusted to the regular equipment clearance according to the regular equipment method.

Aligning bearing

A The bearing of the heating equipment requires that the shaft and the bearing are isothermal and then the equipment clearance is measured again.

B Measure the device clearance again before locking the washer device.

C When the oil pressure nut is replaced by a locking nut, measure the equipment clearance again.

D After the oil pressure discharge of the injection pump, measure the equipment clearance again.

2. Axial positioning and adjustment of shock absorber bearing manufacturers

(1) Pressure mounting method of the inner ring of the aligning roller bearing

A taper shaft with locking nut, end cap, end cap or oil pressure nut directly mounted bearing;

B clamping sleeve with locking nut or oil pressure nut directly press bearing;

C Release bushing shaft Press release bushing to equipment bearing with locking nut or oil pressure nut.

(2) Setting and completion of axial open space

The following four points should be paid attention to when shock absorber bearing collaboration equipment:

(1) It is necessary to pay attention to making bearing equipment and disassembly simple, saving labor, time and expense.

(2) The free end bearing must be able to connect with the shaft and shaft
