The importance of safety production rules in bearing production
Safety production has always been the main emphasis in industrial enterprises, because no matter what process is carried out in the factory, it is more dangerous. In the bearing production, it is impossible to make comparisons without a good production rule. Good products are still the same in bearing production. During the assembly operation of […]
Impact of bearing wear
Bearing wear is diverse. Their basic common feature is that they are limited to a local area, and the bearing wear zone always transitions gradually. The slightest and most normal bearing wear phenomenon is the wear-in bearing wear and the wear of the bearing, but it does not occur under extreme operating conditions. Ideally, it […]
Condition detection and fault diagnosis of rolling bearings
Rolling bearings are important parts in rotating machinery. Statistics show that in rotating machinery using rolling bearings, about 30% of mechanical failures are caused by rolling bearings. With the use of condition detection and fault diagnosis technology, the accident rate can be reduced by 75%, and maintenance costs can be reduced by 25% to 50%. […]
Definition of tapered roller bearings
The single-row tapered roller bearing's ability to withstand axial load depends on the contact angle, that is, the outer ring raceway angle. The larger the angle, the greater the axial load capacity. The most used tapered roller bearings are single-row tapered roller bearings. In the front wheel hub of the car, a small double-row tapered […]
Structural characteristics of tapered roller bearings
The type code of tapered roller bearings is 30,000, and tapered roller bearings are separate bearings. In general, especially in the dimensions covered by GB / T307.1-94 "Tolerances for rolling bearings, radial bearings", the outer ring and inner components of the tapered roller bearing are 100% interchangeable. The angle of the outer ring and the […]
Classification of tapered roller bearings
The single-row tapered roller bearing has an outer ring, an inner ring and a set of tapered rollers, which is an inner ring component formed by a basket-shaped cage. The outer ring can be separated from the inner ring component. According to the ISO standard for external dimensions of tapered roller bearings, the outer ring […]
Uses of tapered roller bearings
Tapered roller bearings mainly bear radial and axial combined loads. Bearing bearing capacity depends on the raceway angle of the outer ring. The larger the angle, the larger the bearing capacity. This type of bearing is a separate bearing, which is divided into single row, double row and four row tapered roller bearings according to […]
Installation of tapered roller bearings
Adjusting the axial clearance For the installation of tapered roller bearings, the axial clearance can be adjusted by adjusting nuts on the journal, adjusting washers and the threads in the bearing housing holes, or by pre-tensioning the spring. The size of the axial clearance is related to the arrangement of the bearing, the distance between […]
Size range of tapered roller bearings
The basic dimensions of ZWZ tapered roller bearings are listed in the dimension data table. Single-row tapered roller bearings: Inner diameter size range: 20mm ～ 1270mm Outer diameter range: 40mm ～ 1465mm Width size range: 15mm ～ 240mm Double-row tapered roller bearings: Inner diameter size range: 38mm ～ 1560mm Outer diameter range: 70mm ～ 1800mm […]
Tolerance of tapered roller bearings
Equivalent dynamic load P = Fr KN] When Fa / Fr≤e P = 0.4Fr + YFa [KN] when Fa / Fr> e When single-row tapered roller bearings are used in pairs (the basic external dimensions can be different), when calculating the equivalent dynamic load of the bearing, the additional axial force caused by the radial […]
