Product Application

S series is one kind of Helical worm gearbox, crafted as Modularization and high-stainless cast iron case. It is combo of helical equipment and worm equipment, which with higher efficiency and strength than basic metal alloy worm gearbox. Because of their outstanding efficiency, these drives can be used in every commercial sector and customized to individual torque and velocity requirements. The gear ratios afforded by the helical-worm gear stage and the reduced noise levels during procedure make these gearmotors best low-cost solutions for simple applications.
Perfect for the machinery and devices of following industry:
• Conveyor & Material handling
• Mining & Quarry
• Crusher & Cement
• Automatic production line & Mixer
• Transport & Packaging
• Food machine & Beverage
• Construction & Metal processing
• Plastic & Chemical industry

Product advantages

1. There is a blend of helical gear and worm gear to increase the torque and effectiveness of the machine. This group of products has total specifications, wide speed spectrum, good versatility, adapt to various installation methods, performance, safety and reliability, long service life, and implementation of international standards.

2. The top of body possesses concave and convex heating dissipation, low temperature climb, low noise and strong vibration absorption.

3. The machine has good sealing performance and strong adaptability to the doing work environment.

4. The machine has high transmission precision, especially suitable for employed in places with frequent starting. It can be connected with various types of reducers and equipped with various types of motor drives. It is usually installed in the 90-degree transmission procedure position.

5. The key elements of the geared motor adopt high wear-resistant materials and have special heat treatment. It has the characteristics of high processing precision, stable transmission, small volume bearing ability and long service life.

6. The reducer can be equipped with numerous kinds of motors to create an electromechanical integration, which completely guarantees the product quality characteristics of the merchandise.
When the RV reducer is working outdoors, it ought to be protected from sun protection, anti-collision and rain. RV reducer should be placed on a set or rigid support surface, and prevent all foreseeable vibrations around. It is best to pre-tighten with a washer. The bolts in the RV gearbox should retain enough lubricant and check regularly. This series of reducer is definitely a common design, employed when the ambient temp does not go beyond + 40 °C. When putting in the pinion equipment at the productivity shaft end of the RV reducer, when the coupling or the pulley is used, the shaft end screw hole pressing method is adopted. It really is strictly forbidden to hammer. RV reducer avoids blending artificial oil with mineral oil. RV reducer is operated for the very first time for 150 time, and should be changed after re-lubricating. The oil modification interval is approximately 4,000 hours.

Pay attention to the following suggestions when installing and installing the apparatus unit
As proven in Figure 1, the gear unit must be securely mounted on the machine to avoid vibration.
2. Check the right rotation path of the output shaft before assembling the reducer on the mechanical gear.
3. When the reducer is placed for a particularly long period of time (4~6 weeks), if the oil seal isn’t immersed in the lubricating oil and exposed, be sure you replace the oil seal. This is for the reason that rubber will adhere to the shaft and also lose its elasticity. . Need to fully restore its functionality.
As proven in Figure 4, whenever possible, avoid the reducer subjected to sunlight and harsh environments.
5. Place the enthusiast head in the surroundings duct to ensure that the motor cools in the right way.
As shown in Amount 6, please contact our technical division if the ambient temperature is below -5 ° C or above 40 ° C.
7, can not paint the paint on the rubber parts.
8, the torque is slowly but surely increased after starting, cannot load the utmost load together.
