【 Jiaxing bearing group co. , LTD. ) The determination of the bearing clearance

There is rotational, have HRB bearing ( ) 【 Jiaxing bearing group co. , LTD. ) The determination of the bearing clearance. 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 cash supply ability. 1. Bearing monomer clearance determination of determination of bearing clearance, bearing vertical platform, pressure bearing outer ring with the hand, keep the inside and outside the ring did not tilt, about 1/2 - turn the inner ring 1 ring, roller is stable. Then around the column of any roller into the upper, respectively. Internal clearance with a feeler, its measuring location and measurement point according to bearing outside diameter size is somewhat different. Outer diameter greater than 200 mm of bearing clearance measurement insert the pin into the bearing is between the above 2 column roller and outer circle and the relative position of bearing center symmetric 2 columns between roller and inner circle position, determination of the bearing internal clearance. Bearing internal clearance ( R） Is that the bearing is above 2 columns between rollers and the outer ring of bearing internal clearance respectively set ( r1) ”( r2) , set in the internal clearance of the bearing is above ( RT） 。 RT = 1/2 ( r1 + r2) The relative position of bearing center symmetric 2 columns of determination of bearing internal clearance between roller and the outer ring and between the two columns on the left of the roller and outer side clearance, set up for rL1 ` rL2, set on the left side of the bearing internal clearance RL. RL=1/2( rL1+rL2） The between two columns on the right side of the roller and the outer side of each clearance for rR1 ` rR2 bearing internal clearance is set on the right side of the rR. rR=1/2( rR1+rR2) Use the type and the bearing internal clearance (r = 1/2 RT+RL+rR) 2. Bearings mounted on the shaft or set set of clearance in determination of bearing outer ring price roller sagging state of clearance. First, ensure the integrity of the bearing outer ring 1/2 - gesture to turn right or left 1, 2 column roller column of any roller was positively at the bottom of the location, respectively. Determination of using feeler clearance, somewhat different parts according to the bearing outer ring outside diameter size. Outer diameter greater than 200 mm of bearing clearance measurement insert the pin into the bearing is between the above 2 column roller and outer ring and the relative position of bearing center symmetric 2 columns between roller and inner circle, the determination of the bearing internal clearance. Bearing internal clearance is r, the bearings are the following two columns between rollers and the outer ring of bearing internal clearance respectively set to rS1 ` rS2, internal clearance on bearing is set to rS. rS=1/2( rS1+rS2) The relative position of bearing center symmetric 2 columns between rollers and the outer ring of bearing internal clearance and 2 column on the left side of determination of clearance between roller and outer ring, respectively, set to rL1 ` rL2, set on the left side of the bearing internal clearance to rL. rL=1/2( rL1+rL2) Between the two columns on the right side of the roller and outer determination of the clearance is set respectively for R1 ` rR2, on the right side of the bearing internal clearance is set for the rR. rR=1/2( R1+R2) Use the type bearing internal clearance. r=1/2( rS + rL + rR) Measure the matters needing attention in the bearing internal clearance and bearing in the determination of such size, measuring instruments and the temperature of the unit under test must be consistent. Especially with the heating oil tank ` bearing induction heater heating installation, measure its internal clearance must be from a state of heating cooling rear can be completely. Bearing from custody warehouse handling to determine, for example, place, bearing temperature may be higher, if the temperature of the bearing is not confirmation of clearance, the size of the measurement, the measurement results may be wrong. Determination of more than 400 mm outer diameter of large bearing clearance, or size, can take place apart packaging bearing on the platform of a day and night, making the temperature at which the measurement is consistent with the environmental temperature. 24-hour customer service hotline: if you are above jiaxing bearing group co. , LTD.
