What is the function of transmission bearing system comprehensive analysis

The house is not strong enough, enough to see how its roots played kind; Cotton-padded jacket can be warm, what breed is depends on the filler, ideally, must have internal support surface talent show a better state. Let us watch the transmission bearing. The role of transmission bearing - — Transmission of bearing request 1, the thought of variable speed drive bearing shape and size. 2, degree of variable speed drive bearing can settle, also can be vertical or inclined to settle. Can be positive and negative rotation. Can be positive and negative input and output power ( The reduction or growth) 。 3, no matter adopt what kind of variable speed drive bearing device, and its connection has the size match the request. Introduce using: d inner circle hole and shaft with press H7 / h6; Circle the pin hole on the do cooperate with transmission of the H7 / r6; With the outer shell and D according to H8 / h7; Drive with the output shaft hole with the use of clearance fit, the interval of 0. 2 to 0. 5mm。 4, variable speed drive bearing axial positioning: axial positioning will stop any of its three laps after, do not need other two shaft axial position again. 5, the rotation direction positioning; Both outer and inner ring is flat key position. The circle is applied location. 6, variable speed drive bearing on radial acceptable smaller force, but unfavorable to accept a larger workload. 7, transmission ratio, all is according to the first device mode of transmission ratio. If using other devices, it should calculate the transmission ratio. 8, at the rated speed ( 1500rpm) The transmission ratio and the required, under power ( 千瓦) The selection of variable speed drive bearing type. 9 and when to work based on torque, need corresponding selection model. 10, reducer, selection of model with variable speed drive bearing model. The role of transmission bearing - — Varieties of deep groove ball bearing structure is simple, use lunch, use the most common. Is mainly used for the radial load, also can accept certain axial load, when the radial clearance is bigger, has the properties of Angle contact ball bearing. Compared with the size of the other kinds of bearings, the bearing has a small friction coefficient, high limit speed, manufacturing high accuracy, easy to finish the features, such as bearing seal is the user's preferred bearing type. （ Double row angular contact ball bearing, ball bearing series, clean bearing) Cylindrical roller bearings belong to this type of bearings do not, devices, and remove the bento, common used for radial load, compared with the appearance of the same size deep groove ball bearings, has large radial load and stiffness, suitable for high load or high rigidity request. Tapered roller bearing is mainly used for accepting to mainly consisting of radial load and axial load, has higher bearing ability, but the manufacturing precision is difficult to progress, high noise, shall not apply to the high speed and low noise. Needle roller bearing needle roller bearing: ( Stamping, thrust, needle, adhere to the frame components) Because of the compact structure, small radial size, large load capacity, especially suitable for the limited size of radial gear bearing parts, with mechanical equipment to small HuaQing quantitative development request. Linear bearing linear ball bearings mainly use straight line reciprocating movement of the parts in the mechanical equipment, has a small friction, movement sensitive, and repair a change in lunch, etc. Clutch bearing this kind of product structural style is mainly stamping outer garment type angular contact ball bearing and single side band rubber seal type two kinds of angular contact ball bearing, common for outer ring spinning, can't use alone, general need to cooperate with cast iron sleeve. The product is gradually replaced by the automatic self-aligning clutch bearing separation. （ Automatically self-aligning clutch bearing separation assembly, automatic self-aligning, short-lived life, light weight and other characteristics; Have to reduce the noise, reduce wear and damage of the matching parts of the function. The center of local is a set of angular contact ball bearing) 。 Transmission bearing role will auto transmission is directly related to its function, auto transmission must meet all kinds of requests, including shift smoothly and high output power, compact structure, light weight, high efficiency and low noise, etc. , and for these requests higher and higher. Therefore, transmission bearing performance also must satisfy the higher request. This is to develop the warp and woof of auto transmission bearing.
