[1], standard constraints. Generally TIMKEN bearings can be constrained by the space of the equipment. In most cases; the shaft diameter (or TIMKEN bearing inner diameter) is based on mechanical depiction or other depiction constraints. So TIMKEN bearing type And the selection of the standard is based on the inner diameter of the TIMKEN bearing. Thus; the standard standard table of the standard TIMKEN bearing is based on the world standard inner diameter standard. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
The standard method of standard TIMKEN bearings is complicated; the best TIMKEN bearings are used in the description of mechanical equipment (this describes whether TIMKEN bearings can be easily acquired; here is a topic of off-topic; some imported TIMKEN bearing catalogues do have the type; However, some non-standard TIMKEN bearings are not in stock in mainland China; some time-divided futures will be very long; so in the TIMKEN bearing selection, we must consider the time cost and the cost of the later replacement) TIMKEN bearing load; the load applied to the TIMKEN bearing Its nature, size, and direction are changeable. Generally; the extra fundamental load is shown on the standard table. But the axial load and radial load, etc.; is also an important factor in selecting the appropriate TIMKEN bearing. When the ball and roll When the standard of the needle bearing is equal; the needle bearing generally has a higher load and can accept a large oscillation and impact load.
[2], the speed; the allowable speed is based on the type of TIMKEN bearing; standard; accuracy; cage type; load; smooth method; and cooling method and other factors. The TIMKEN bearing table lists the standard precision TIMKEN bearing in the oil smooth and Allowable speed of grease under smooth. General; deep groove ball bearings, active self-aligning ball bearings and cylindrical roller bearings are used in high-speed work.
[3], TIMKEN bearing public service; TIMKEN bearing standard accuracy and rotation accuracy are based on ISO and JIS standards. For high-precision and high-speed working machinery; TIMKEN bearings with 5 or more precision are recommended; deep groove ball bearings, The heart thrust ball bearing or cylindrical roller bearing is used for high working precision mechanical rigidity. When the TIMKEN bearing's moving body and raceway contact surface are pressed; elastic deformation will occur. Some mechanical requirements will reduce the elastic deformation to the minimum. The sub-bearing is smaller than the elastic deformation of the ball bearing. [4] In some cases, the TIMKEN bearing is preloaded to add rigidity. This procedure is generally used for deep groove ball TIMKEN bearings, radial thrust ball bearings and tapered rollers. Bearing inner and outer ring offset; shaft tortuosity; shaft or TIMKEN bearing box public service change; cooperation fault will lead to the inner and outer ring of the pain. To avoid excessive pain angles; active self-aligning ball bearings; active spherical roller bearings; Or self-aligning bearing housing is the best choice. å—“ audio frequency and torque; dynamic bomb TIMKEN bearings are produced according to high-precision standards; so the voice and torque is small. Deep groove ball bearings, and cylinder About bearings combined with low voice; low torque applications have unique needs.
[5], equipment and disassembly; some occasions are often disassembled and equipment; to ensure that they can be inspected and repaired according to their location. TIMKEN bearings that can separate the inner and outer rings, such as: cylindrical bearings; needle bearings; The bearing is very suitable for this occasion. The tapered self-aligning ball bearing and the active spherical roller bearing are assisted by the bushing; the same simplifies the equipment program.
