Wind Turbine Reducer
The DLHZ series rotary speed reducer is an ideal transmission unit for lifting machinery. Its perfect performance ensures that the crane structure operates reliably under harsh and harsh environments and is easy to install and maintain. Hardened gears and high-quality production processes ensure the superior quality and performance of the device.
The supports and housing are made of ductile cast iron resin sand, and the output shaft and output pinion are made of high-standard forged steel. The freely changing support body and output shaft length, flexible speed ratio and pinion parameters can meet your different design needs. The rotary speed reducer is mainly used for cranes, gantry cranes, and slewing mechanisms for cranes on ships, decks, ports, and offshore platforms. Other rotary motion equipment can also be used.
At the same time, according to your special requirements, we can provide non-standard rotary devices that meet various sizes and performances.
(1) Compact structure
(2) Gear structure modular
(3) Long lasting
(4) High mechanical efficiency
(5) Low noise
(6) Simple installation and maintenance
Design of Reducer
(1) Slewing mechanism
Output torque from 6500 to 420,000 Nm. For more specifications, please contact us.
Transmission ratio 20 to 280.
(2) Design standards
The company has excellent design concepts and technical means, consistent research and development of products, making the product highly competitive in the market. With reference to the GB3811-83 standard, the classification of the load status, the utilization level of the organization, and the corresponding working level of the organization are determined; the working levels of other organizations are corrected by the coefficient K.
The nominal output torque TNom in the sample table, the collective load state L2, and the utilization class T5 correspond to the agency work level M5.
Maximum output torque TSTAT refers to the operating torque under static or long-term intermittent operation, ie when the peak value or starting torque is reached for a short time.
Calculating the output torque Tc refers to the operating torque of the device under acceleration, deceleration, and wind and tilt conditions.
(3) Sealing and lubrication
The output of the long shaft is sealed by a double radial shaft seal and the lower end is greased. Each joint is installed. The seal ring is coated with Loctite flat sealant to ensure that there is no leakage of oil on the flat surface.
Lubricant change intervals and lubricant selection can be found on page 17. The speed reducer is not lubricating oil at the factory, and the user can add appropriate amount of lubricating oil to the reducer according to the special oil recommended in the table and add it to the oil label window 2/3.
Proper selection and replacement of oil will increase the maintenance time of the equipment and increase the service life of the equipment.
The oil discharge position is generally below the mounting flange, connecting the wire hose to the oil. Please submit if there are other requirements.
The installation position
Vertically mounted, with pinions down. Please install the horizontal installation method in advance.
The mechanical efficiency n of the two-stage transmission is not less than 96%; the mechanical efficiency of the three-stage transmission n is not less than 94%.
The standard appearance is a two-group zinc-rich primer, light gray; the topcoat is a two-component epoxy. Sky blue. In harsh environments. If you have special requirements, please specify.
The output pinion
The pinion displacement coefficient x = 0 5. The gear accuracy is 8 levels.
The pinion uses low-carbon alloy steel or medium-carbon steel, and the heat treatment hardness can reach HB270-IRC62. Specific requirements when ordering the parties to implement the consultation.
Rotary reducer is designed according to the ambient temperature range -20°C～+40°C. Permissible oil temperature +90°C.
If work in harsh environments, such as salt water, salty air, dust, mud, high pressure, strong vibration, strong impact, ambient temperature, corrosive media, etc., will affect the performance of rotary speed reducer, please explain in advance to ensure Safe design.
This product can be widely used in the field of lifting machinery，including bridge crane, gantry crane, tower crane, mobile crane, gantry crane, elevator, cable crane, mast crane and mechanical parking equipment.
All exported gearboxes covered with Anti rust oil and plastic film, then packed in wood box with Fumigation.
