ZYS ball bearing installation method

A ZYS ball bearing installation method: press-fit: the bearing inner ring and the shaft so that a tight fit, the outer ring with the bearing hole is relatively loose fit, can be pressed press the bearing on the shaft, then the shaft along with bearing fitted together the bearing hole, when the pressure mounted on the inner end surface of the bearing pad material is made of a soft metal mounting sleeve (copper or soft steel), bearing outer ring with the bearing hole tight fit, the inner ring and the shaft is loose When fit, the bearing can be pressed into the bearing hole, then assemble the outer diameter of the sleeve seat should be slightly smaller than the diameter of the hole. If the bearing ring and the housing bore and shaft are a tight fit, installation of interior and outer ring To simultaneously pressed into the shaft and housing bore, the assembly casing shall be constructed simultaneously charging tight end face bearing inner and outer rings.
Two ZYS ball bearing installation method: heating with: by heating bearings or bearing, the use of thermal expansion close fit into a song with the installation method is a commonly used method of installation and labor-saving method is suitable for this large amount of interference bearing. installation, before loading the bearing or separable heat bearing rings into the tank uniform heating 80-100 ℃, then remove from the oil loaded onto the shaft as quickly as possible in order to prevent the cooling inner face and shoulder fit not tight, you can then fasten the rear bearing axial cooling when the bearing outer ring and light metal bearing tight fit, using heat bearing hot charging method, can be avoided with the surface by scratches. When the tank is heated by bearing a certain distance away from the bottom of the gate should have a net, or with a hook hanging bearings, can not be put on the bottom to prevent impurities entering the bearing Shen or uneven heating, the tank must have a thermometer, strict control of the oil temperature must not exceed 100 ℃, in order to prevent tempering effect, reduce the hardness of the rings.

ZYS ball bearing properties

Deep groove ball bearing are most representative of the rolling bearing, widely used. For high speed or high speed operation, and very durable, without regular maintenance. This kind of bearing friction coefficient is small, extreme high speed, simple structure, low cost, easy to achieve high manufacturing precision. Size range and diverse, used in precision instruments, low noise motors, automobiles, motorcycles and general machinery industries, the machinery industry, the most widely used class of bearings. The main radial load, but also can withstand a certain amount of axial load.
Select a larger axial clearance radial load carrying capacity increase, when the contact angle of pure radial force is zero. When the axial force, the contact angle is greater than zero. Commonly used stamping Ribbon Cage, machined solid cage, sometimes with nylon frame.
sealed angular contact ball bearing installed in the shaft, the axial clearance in the bearing within the shaft or housing to limit the two directions of the axial displacement, it can be positioned in the bi-axial direction. In addition, the class also have some bearing self-aligning capability, when compared to shell hole tilt 2 'to 10', still work, but have a certain influence on bearing life. ZYS ball bearing cages are mostly steel stamping Ribbon Cage, a large multi-use vehicles bearing metal solid cage.
ZYS ball bearings are the most commonly used bearing. It's simple and easy to use. Mainly used to bear radial load, but increase the bearing radial clearance, with a certain angular contact ZYS ball bearing performance, can withstand radial and axial load. When should not be used in high speed and thrust ZYS ball bearings, it can also be used to bear pure axial load. With ZYS ball bearing specifications same size compared to other types of bearings, bearing friction coefficient is small, high speed limit. However, the impact of intolerance, not suitable to withstand heavy loads.

ZYS ball bearings

Super precision ball bearings are mainly made up of four basic elements: Ball (ball), the inner ring (inner ring), the outer ring (outer ring) and the holder also called retainer (cage or retainer). General industrial use of ZYS ball bearings to meet the AISI standard, ball and ring 52100 is usually high chromium steel, Rockwell hardness (Rockwell C- scale hardness) of between about 61-65. While maintaining the hardness of the ball and ring compared to low, the material with metal (such as: carbon steel, aluminum alloy) or non-metallic (eg: Teflon, PTEF, polymer materials). ZYS ball bearing (ZYS ball bearing) than the journal bearing (journal bearing) rotation friction is small, so the same speed, temperature will be relatively low friction Angular contact thrust ball bearing is a rolling bearing, ball ball mounted on inner and outer rims intermediate steel ring, can withstand a greater load. Also known as ZYS ball bearings.
