Guangzhou chaozhou bearing manufacturer to speed all the way forward

Guangzhou chaozhou bearing manufacturer to speed all the way forward at a speed of rolling bearing is limited. It is normal, the limit speed by the working temperature of smooth agent or data set of bearing parts. To limit the speed of working temperature depends on the bearing friction heat created during the operation, Including any external heat) Quantity and bearing can distribute heat. Bearing type and size, internal design, load, smooth and cooling conditions, and insist on frame design, precision and internal clearance, will affect the speed capacity is. Listed in the product table, usually two kinds of speed: ( Hot) Reference speed and ( Movement) Speed limit, its value depends on the thinking of the specification. Reference speed products listed in the table ( Hot) Reference speed is a reference for sure bearing under the certain condition of load and smooth oil viscosity allows running speed. Listed in the reference speed values agree with the ISO 15312 ( Do not include thrust ball bearing) 。 The ISO specification is applicable to oil is smooth, smooth as effective but for grease. Given the high temperature bearing reference speed on behalf of its speed in a specific operation conditions. Under this kind of speed, the heat generated by the bearing from bearing to the shaft, bearing and heat dissipation of smooth agent to equilibrium. According to ISO 15312, to reach the thermal equilibrium of the reference condition is: - - Environment temperature is 20 degrees Celsius to add 50 degrees, bearing temperature, 70 degrees Celsius. Measurement points for bearing outer ring fixed or bearing washer; - - Radial bearing: the stability of radial load, static load ratings - C0 is 5% - Thrust bearing, the stability of the axial load, static load rating of 2% - With normal clearance smooth open bearings bearing oil: smooth agent: does not contain mineral oil extreme pressure additives, 70 & deg; The kinematic viscosity = 12 c was/s ( ISO VG 32) ( For radial bearing) 24 square mm/SEC (= ISO 68 VG) For thrust roller bearing - - Smooth way: oil bath, when the roll in the low position, smooth oil arrived in the middle. Smooth grease for bearings is smooth, smooth agent: 40 & deg; Viscosity of 100 to 200 was under c/s ordinary smooth lithium soap grease (mineral oil Such as ISO VG 150) - - Smooth fat quantity: about 30% of bearing internal and comfortable space. Smooth fat smooth bearing temperature peak may be present when it is started. Therefore, bearing may need 10 to 20 hours of ability to reach normal operating temperature. Under the condition of these particular, smooth smooth oil and fat equals the reference rate. When the bearing outer ring rotates, derate may demand.
