Introduction to main technology of suspension reducer

Suspension reducer is a kind of vertical reducer, which is a three-stage transmission involute cylindrical gear reducer. The three-stage cylindrical gear transmission is mainly used for driving, and it can also be used as other reducer devices. The suspension reducer is mainly used for the deceleration transmission of public mechanical equipment such as mining, metallurgy, cement, construction, chemical industry, light industry, etc., and is suitable for the workplace where the loose structure restricts the use of vertical installation. Applicable occasions can be widely used in metallurgy, mining, chemical industry, building materials, lifting, transportation, textile, papermaking, instruments, plastics, rubber, engineering machinery, energy, etc

Features of suspended gear reducer:

(1) The center distance, nominal transmission ratio and other main parameters have been optimized, and the interchangeability of main parts and components is good.

(2) Gears are made of high-quality alloy steel by carburizing and quenching, and the tooth surface hardness reaches 58-62hrc.

(3) Small size, light weight, high precision, large bearing capacity, high efficiency, long service life, high reliability, stable transmission and low noise.

(4) Generally, oil pool lubrication and natural cooling are used. When the thermal power cannot be met, circulating oil lubrication or fan cooling coil cooling can be used.

Scope of application：

(1) Input speed n1 ≤ 1500r/min generally.

(2) The circumferential speed of gear transmission shall not be greater than 20m / s.

(3) The working environment is -40-50 ℃. If it is lower than 0 ℃, the lubricating oil should be preheated to above 0 ℃ before starting. This reducer can be used for both positive and negative directions.

Maintenance and installation of suspended reducer

1. The high-speed shaft and other parts are matched, and direct hammering is not allowed. Screw in the screw hole at the shaft end and press the screw into the coupling.

2. After the reducer is installed, it can be commissioned only after it is rotated by hand without jamming.

3. Under the condition of no load, if you find abnormal sound, excessive heating or oil leakage after running for 2 hours, you should stop immediately to eliminate it.

4. When installing the tension arm, try to make the tension arm perpendicular to its fixed point and the connecting line of the output shaft, with a deviation of +10 °, and make the tension arm in a tensile stress state.

L-ckc150 intermediate pressure gear oil is recommended for reducer lubrication. When the backstop is used, lubricating additives containing molybdenum disulfide or the like should not be used in the reducer. After the first refueling, replace with new oil after 200 hours of operation. After continuous operation, change the oil every half a year or 2500 hours.
