Bearing oiling: angular contact bearings installed back to back to work

Machine tool spindle bearings, bearing a measuring instrument, the rated speed RPM) , according to the transmission ratio and the required power ( 千瓦) The selection of variable speed drive bearing type. Suitable for motor, generator, especially variable frequency motor is applied more widely, in order to block the current flows through the bearing, we have to cut off the circuit, so that insulation bearing and insulation bearing chamber was born. Bearing clearance code: C: standard clearance code, the code omitted in the bearing type is not marked as C: clearance slightly smaller than the standard clearance C: clearance slightly larger than the standard clearance C: slightly larger than C clearance C: C slightly larger than the clearance of rolling bearing radial clearance standard note: junior partner with bearing type and inner diameter size and clearance level, corresponding to the corresponding standard form to query the bearing clearance. Transmission bearing performance, therefore, must also meet the requirements of higher, code of rolling bearing GB/T - The composition of the rolling bearing code and representation. Linear bearing the features of lightweight, corrosion resistance, compatibility, low cost, etc. , before installing the linear bearing must first be clear on the surface of the machinery installation burrs, dirt and surface scars. Select - transmission characteristics - - Extruder operating characteristics of the so-called extruder operating characteristics, refers to the screw rotation speed and the relationship between the driving power and torque. Therefore, in many parts of the automobile and engineering machinery materials used as lubricating grease, namely we often say butter! The role of the grease is mainly lubrication, protection and sealing. Creep inside or outside surface skid, mirror or change, sometimes gets stuck, reason:; Rust electric erosion caused by the development; Bad lubrication. Due to the irregular motion of rolling body caused by the skid. Hot working performance is good, measures: to research lubricant, lubrication methods; Check the conditions of use; Set appropriate preloading; Improved sealing performance; Normal use of the bearing. The first kind of circumstance, the iron bearing chamber, it is recommended that you check with the bearing chamber, the question was much easier than the above, mostly with loose! According to some bearing ( NSK SKF) Information is introduced: the bearing outer ring and the degree of the bearing chamber with bearing ring to indoor creep in bearing, get the uniform makes the bearing outer ring so wear and prolong the service life of bearing, excuse me reasonable? A: you said, is refers to the axial creep, the peristalsis is to absorb the axial expansion. In strict accordance with the proportion of mixed sauvy SDH material and coating to the bearing wear surface, solid tooling, treatment of iodine tungsten lamp heating and accelerate the curing speed. Guide is also called the slide rail, linear guide, linear slide rail, used for straight line reciprocating movement situation, has higher rated load, than the straight line bearing can bear the constant torque at the same time, can be achieved under the condition of the high load and high precision linear motion.
