Introduction to main technology of suspension reducer

Views: 0     Author: Site Editor     Publish Time: 2022-07-05      Origin: Site

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. Main technical parameters rated power: 1.1 ~ 193kw allowable torque: 180~17000n M input speed: 750 ~ 1500 output speed: 25 ~ 300 installation form: shaft mounted suspension reducer model: dxg30 DXG 40 DXG 45 DXG 50 DXG 60 DXG 70 DXG 80 DXG 100 DXG 12


FAQ

  • Where is your product mainly exported?

    Our products are mainly exported to Japan, the United States, Germany, Southeast Asia and other countries and regions. Our customers include many OEM customers specializing in construction machinery. We have partnered with several of the Fortune 500 companies to become one of their major foundry suppliers in China.
  • How to provide goods?

    Usually we will ship the goods to the sea. The factory is only 460 kilometers away from the port. It is very convenient and convenient to transport the goods to any other country. Of course, if your cargo is very urgent, Ningbo Airport and Shanghai Airport are also nearby.
  • What is the payment term?

    When we offer you a quote, we will confirm the transaction method with you, FOB, CIF, CNF, etc. For large-scale production, you need to pay a 30% deposit before production and a 70% balance on the copy of the document. The most common way is T/T. Letter of Credit is also acceptable.
  • How to ensure the quality of your products?

    First, we will check after each process. For finished products, according to customer requirements and international standards.
  • How many employees does your company have? What is the relationship between technicians?
