Reducer is a mechanical transmission in many areas of the national economy, the industry involved in a variety of product categories, including a gear reducer, planetary gear reducer and worm reducer, also includes a variety of special gear, such as the growth rate of devices, speed devices, and various types of composite transmission device includes a flexible gear including so on. Goods and services in the field involved in metallurgy, nonferrous metals, coal, building materials, shipping, water, electricity, construction machinery and petrochemical industries. 1. The drive gear reducer Siemens main technical parameters than: i = n1 / n2, n1 for input speed reducer repair Tianjin, n2 output speed. Siemens gear ratios is to make sure the tape running speed of one of the main technical parameters, in order to gear selection of high-strength steel cord belt conveyor maintenance standards reducer, for example, the original drive motor, drive roller unchanged, original belt speed : V = 2.55m / s drive drum diameter: D = 0.82m motor rated speed: N = 1470r / min can be drawn therefrom: n1 = 1470 r / min, n2 = 2.55 × 60 ÷ (3.14 × 0.82) = 59.422 r / min, thus can be drawn from the transmission gear ratio of i = 1470 ÷ 59.422 = 24.738. 2. Maximum torque gearhead: TA (such as peak torque, starting torque or braking torque). This parameter is mainly derived from technical parameters or tape machine design parameters of the original old gearhead. Output shaft torque calculation formula: T = P × 9550 ÷ n2, P for motor power. 3. gearbox rated power: P2N, this value should be greater than or equal: rated power factor × working machine work machine.
