1.The basic parameters
This type of deep groove ball bearing consists of a outer ring, an inner ring, a set of steel ball and a set of cage.Deep groove ball bearing type has a single row and double row two kinds, deep groove ball structure is sealed and open two kinds of structure, open without sealing structure refers to the bearing, seal type deep groove ball into dust seal and oil seal.Dustproof cover gasket material for sheet metal, only simple prevent dust from entering the bearing raceway.Oil type for the contact seal, can effectively prevent the grease within the bearing.
Single row deep groove ball bearing type code is 6, double row deep groove ball bearings, code-named 4.Its structure is simple, easy to use, is the most common production, the most widely used type of bearings.
2.working principle
Deep groove ball bearings mainly take radial load, also can bear radial load and axial load at the same time.When its only bear radial load, the contact Angle is zero.When deep groove ball bearings with larger radial clearance, with the performance of angular contact bearings, can withstand large axial load, deep groove ball bearing friction coefficient is small, the limit rotational speed is high.
3.Bearing characteristics
Deep groove ball bearing is the most representative of the rolling bearing, widely used.Suitable for high speed and high speed running, and very durable, need not often maintenance.These bearing small friction coefficient, high limit speed, simple structure, low manufacture cost, easy to achieve high manufacture precision.Size range and variety in form, used in precision instrument, low noise motors, automobiles, motorcycles and general machinery and other industries, is the most widely used type of bearings in machinery industry.Mainly bear radial load, also can withstand a certain amount of axial load.
Choose the larger radial clearance when the axial bearing capacity increases, under pure radial force when the contact Angle is zero.With axial force, the contact Angle is greater than zero.Generally adopts the stamping ribbon cage, car solid cage, sometimes also used nylon frame.
Deep groove ball bearings mounted on a shaft, within the scope of the axial clearance of bearing, can limit shaft or the shell axial displacement in two directions, so can in two-way axial positioning.In addition, this class also has a certain bearing capacity, when compared with the shell hole '2 ~ 10', can still work normally, but had certain influence on bearing life.Deep groove ball bearing cage for stamping steel ribbon cage, large bearing use car more metal solid cage.
Deep groove ball bearing is the most commonly used rolling bearing.Its structure is simple, easy to use.Is mainly used to bear radial load, but when increasing the bearing radial clearance, has certain properties of Angle contact ball bearing, joint can withstand diameter and axial load.In high speed and should not be using thrust ball bearing, could also be used to carry pure axial load.With deep groove ball bearing size is the same the other types of bearings, such bearing small friction coefficient, high limit speed.But don't impact resistance, not suitable for carry heavy load.
4.Structure classification
Type of bearing
A, single row deep groove ball bearings
B, single row deep groove ball bearing with dust cover
C, with dust cover, sealing ring of single row deep groove ball bearings
D, on the outer ring groove and stop stop ring of single row deep groove ball bearings
E, have put the ball deep groove ball bearing gap
F, double row deep groove ball bearings
According to the size of deep groove ball bearing can be divided into:
(1) the miniature bearing, nominal diameter size range for 26 mm below the bearing;
(2) small bearings - 28-55 mm size range for the nominal diameter of bearing;
(3) the small and medium-sized bearings - size range for the nominal diameter of 60-115 - mm bearing;
(4) medium bearing - size range of 120-190 - mm nominal diameter of the bearing
(5) large bearing - size range of 200-430 - mm nominal diameter of bearing;
(6) oversize bearings, size range for the 440 mm above the nominal diameter
5.application
Deep groove ball bearing can be used for transmission, instruments and meters, electric machinery, household electrical appliances, internal combustion engines, transportation vehicles, agricultural machinery, construction machinery, engineering machinery, the yo-yo roller type rollerblading, etc
6.Installation method
Deep groove ball bearing installation method one: force fit: bearing inner ring and shaft tight fit, outer ring and bearing hole is a loose fit, available press the bearing pressure equipment in the shaft first, then put the shaft together with the bearing load bearing hole, when pressed on the bearing inner ring end face, cushion the assembling casing made of a soft metal material (copper or mild steel), bearing outer ring and bearing hole tight fit, inner ring and the shaft is a loose fit, the bearing can be pressed into the bearing hole first, then assembling casing diameter should be slightly less than the diameter of a hole. If the bearing ring and shaft and hole is a tight fit, install indoor ring and outer ring to pressure into the shaft and hole, at the same time assembling casing structure should be able to at the same time, so the bearing inner ring and outer ring end face.
Deep groove ball bearing installation method 2: heating cooperates: through heating bearing or bearing seat, by using thermal expansion will fit into a loose fit method of installation. Installation method is a kind of common and energy saving. This method is suitable for interference quantity larger the installation of the bearing, the bearing before hot charging type or separable bearing ring into the fuel tank even heat 80-100 ºC, and then loaded on the shaft, as soon as possible out of the oil to prevent inner ring after cooling end face and the shoulder joint is not tight, to axial bearing cooling can then tighten. Bearing outer ring and light metal bearing seat tight fit, by heating the hot charging method of the bearing, can avoid the mating surface scratch.Heating tank with bearing and should be at a certain distance from the bottom of a mesh, or hanging hooks in the bearings, bearing on the bottom, in case of heavy impurities into the bearing or uneven heating, fuel tank must have a thermometer, strictly control the oil temperature shall not exceed 100 ºC, in order to prevent the tempering effect, reduce the hardness of the ring.
7.tolerance
All have a common standard deep groove ball bearing, consistent with GB307.1.
8.clearance
Standard deep groove ball bearing with C2, standard level (CN), C3, C4 and C5 internal clearance, all consistent with GB4604.
9.Retainer
Deep groove ball bearings generally USES the steel plate stamping entities cage or brass cage.When diameter less than 400 mm, USES the steel plate stamping cage without post code, when the diameter is larger than 400 mm multi-purpose rear brass cage without entity code.
10.three processing form of bearing
Deep groove ball bearing parts processing form is as follows:
A, machining: general bearing production need 20 ~ 40 working procedure, much more than 70.
B. Processing: bearing parts of the surface of the work are rotary forming surface, suitable for molding in processing.
C, precision machining: most of the surface to bearing parts after grinding, grinding size and geometric accuracy in microns. |
