The interference fit and application of bearing

The installation of the cone bearing always USES the interference fit. The decrease of the radial internal clearance value, or inner ring in the cone axis neck axial displacement, were used to determine and measure ( cè liáng) The amount of interference. Measurements ( cè liáng) There are many different ways to interference. 1. Measured with a feeler gauge, cè liáng) The decrease of the clearance value. 2. Measuring the lock nut tightening Angle. 3. Measurements ( cè liáng) The axial distance. Thin wall bearings manufacturer of angular contact ball bearings can match the optimal number of balls and the contact Angle of 30 °. They support radial load is higher than contact bearing deep groove ball bearings or four o 'clock, and can support comes from the same direction of axial load. In view of the special demand, 4. Measuring the inner ring ( 膨胀) The amount. Measured with a feeler gauge, cè liáng) The clearance reduction is bearing ( 轴承) Before and after installation, measured with a feeler gauge, cè liáng) Radial internal clearance of the method is suitable for large and medium-sized spherical and CARB bearings. It is best to measure between outer ring and no-load roller clearance. Measurements ( cè liáng) Lock nut tightening Angle lock nut tightening Angle measurement is an effective method of verified ( 方法) That can be used to determine the cone shaft neck on the right of small and medium-sized bearing interference degrees. Tighten Angle values has been established, and the guidance of a help pinpoint bearing on the cone shaft neck. Measuring the axial forward distance installation cone bearing ( 轴承) , can be measured by ( cè liáng) The inner ring on the shaft neck forward distance s to complete. Bearing the use of clean environment for bearing is very important. Such as cross section thin-walled bearing ring rotation surface and rough surface precision of the rolling element is about 1/10 microns, this smooth surface of the ball if polluted, its influence is very serious. Axial forward distance guidance value, see related products ( 产品) Part. However, more suitable for the method of this kind of circumstance, 方法) Is; SKF propulsion method; 。 This kind of installation method provides a reliable and convenient way of interference quantity. By controlling ( 控制) Bearing ( 轴承) Relative to the desired location of axial displacement, which can realize the correct fit. This method USES is equipped with the dial gauge hydraulic nut, and installed on the selected pump specially calibrated ( 校准) The digital measurement. Essential oil pressure and axial displacement of a single bearing, the definite value for precise positioning of the bearing. The measuring inner ring expansion by measuring the expansion of the inner ring ( 膨胀) Quantity, can be simple and very accurately determine the large number of spherical and CARB bearings in the correct position of the journal. This kind of measurement ( cè liáng) , you can now use SensorMount® It USES a bearing inner ring with integrated sensors, a dedicated handheld indicator and ordinary hydraulic ( hydraulic) Installation tools. Bearing size, shaft, materials or design - finish Problems in aspects of solid or hollow, all need not be considered.
