Jiaxing bearing small make up to introduce you to the selected bearing matters needing attention

There is rotational, have HRB bearing ( ) Jiaxing bearing group sales co. , LTD. ( The company) Is bearing group co. , LTD. Established in jiaxing spot sales window, specializing in HRB brand bearings, facing the whole country, the existing stock 50 million yuan, covers the whole bearing, have very strong spot supply, is the group's retail sales center. Bearing type selected choose bearing type, fully grasp the using conditions of the bearing is very important. The following table lists the main project: analysis project, select method 1) Bearing installation space, can hold in bearing installation space bearing type, due to the design of shafting pay attention to the rigidity and strength of shaft, so generally, first determine the diameter of axle, bearing inside diameter. But rolling bearing series of a variety of sizes and types, should choose the most suitable type of bearing. 2) Load, bearing load size, direction and nature [ Bearing load capacity with basic rated load, according to the values shown in table bearing size] Bearing load abound change, such as the size of the load, if only the radial load, axial load is a one-way or two-way, the degree of vibration or shock, and so on. After considering these factors, and then to select the most appropriate type of bearing. In general, the same inner diameter of the bearing radial load capacity increasing in the following order: deep groove ball bearings (angular contact ball bearings < < < circular cone roller bearings cylindrical roller bearing, spherical roller bearing. 3) Speed, can adapt to mechanical speed bearing type [ To benchmark the threshold of the bearing rotating speed in limiting speed, its value is shown in table bearing size] Bearing limit rotational speed is not only to take on bearing type is limited to the bearing size, cage type, precision grade, load condition and lubrication method, etc. , therefore, when the choice must consider these factors. Most of the following bearings used in high speed rotation: deep groove ball bearings, angular contact ball bearings, cylindrical roller bearings. 4) Rotating accuracy, has the required rotation accuracy of bearing type [ The dimensional accuracy and rotation accuracy of bearing is not the GB by bearing type standardization] Machine tool spindle, gas turbine, and control machine, high rotating accuracy, high speed and low friction, at this time should be used more than 5 level precision bearing. Generally use the following bearings: deep groove ball bearing, contact ball bearing, cylindrical roller bearing. 5) Rigidity, which can meet the mechanical shafting needed rigid bearing type [ Bearing the load, the part of the rolling element and raceway contact will produce elastic deformation. 'high rigidity is refers to the deformation of the elastic deformation smaller] Reduction device at the end of the spindle and auto parts, such as to raise the axial rigidity of at the same time, also must improve bearing rigidity. Roller bearing the load deformation than ball bearings. (on bearing preload Negative clearance) Can improve the rigidity. The method is suitable for angular contact ball bearings and tapered roller bearings. 6) Inner ring and outer ring of relative tilt, analysis of the bearing inner ring and outer ring tilted relative factors ( Such as load caused by the deflection of shaft, shaft, and the precision of the shell bad or installation error) And choose to adapt to the conditions of use of the bearing type. If the inner ring and outer ring is too big, the relative tilt internal load bearing will cause damage. So should choose the types of bearing can withstand the tilt. In general, allowed to tilt Angle ( Or the heart) Increasing in the following order: cylindrical roller bearings, tapered roller bearings, deep groove ball bearings, Angular contact ball bearing) And spherical roller ( The ball) Bearings. 7) Installation and removal, check the installation of such as frequency and installation method of the frequent installation, use of inner ring and outer ring separable cylindrical roller bearings, needle roller bearings and tapered roller bearing is more convenient. Conical bore self-aligning ball bearing and taper hole spherical roller bearings by using fasteners or withdrawal sets can be convenient for installation.
