Variable speed bearing and linear bearing

Tweet

Linear bearing features: the linear bearing is used with quenching linear shaft, load ball and quenching shaft for contacts, but when linear motion, allowable load is small, high precision, minimum friction resistance, quick movement. For infinite linear motion system. Linear bearing has been widely applied to electronics, food machinery, packaging machinery, medical machinery, printing machinery, textile machinery, machinery, equipment, nc machine tools, robots, tools, machinery, automobile and other general or special machinery industry. Ball Bearing is widely used in electronic equipment, tensile testing machine and digital precision equipment such as 3 d coordinate measurement equipment, and multi-axis machine tools, tools, grinding machines, printers, punch press, automatic gas cutting machine, card sorting machine, industrial machinery, such as food packages installed the sliding parts. Linear bearing is composed of a cylindrical outer ring and multiple columns of steel ball and adhere to the frame. Bearing can do reciprocating linear motion on the shaft. Steel ball more than the number of columns, friction small, long service life, light and flexible, easy to repair and care replacement.

For unlimited travel used with cylindrical shaft. Because point contact ball bearing with shaft, so using the load is small. Steel ball with minimal friction spinning, linear bearing is a kind of linear motion system at low cost production, which can obtain high precision of smooth movement. 1, The appearance of variable speed drive bearing and the connecting size reference. 2,Variable speed drive bearing level can be settled, can also be placed vertical or inclined. Can be positive and negative rotation. Can be positive and negative input and output power (that is, to slow down or growth) 3,No matter adopt what kind of variable speed drive bearing device, and its connection are size requirements. Recommended use: d inner circle hole and shaft with the pin hole in the circle of H7 / h6 do cooperate with transmission of the H7 / r6 with the outer shell and d according to H8 / H7 transmission with the output shaft hole with the use of clearance fit, the interval is 0.2 ~ 0.5 mm 4, Variable speed drive bearing axial positioning: will any of its three laps after axial positioning, 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 the use of transmission 6, Variable speed drive bearing on radial can bear the external force of smaller, but unfavorable to accept large working load. 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, Rated speed (1500 RPM, according to the transmission ratio and the required power (Kw variable speed drive bearing type selected. 9 When based on the working torque, need corresponding selection model. 10 Reducer selection of model with variable speed drive bearing model.
