The main transmission structure of the planetary gear reducer is: the planet wheel, the sun wheel, the inner ring gear. Planetary reducer because of structural reasons, the single stage reduction of the minimum of 3, the maximum general not more than 10, the common reduction ratio is: 3/4/5/6/8/10, the speed reducer series is generally not more than 3, but there is a part of the reduction ratio of customized reducer has 4 reduction. Relative to other reducer, planetary reducer with high rigidity, high accuracy (single level can be done within 1 minutes), Gao Chuandong efficiency (single level in 97%-98%), high torque / volume ratio, life maintenance and other characteristics. Because of these characteristics, the majority of planetary reducer is installed in the stepper motor and servo motor, used to reduce the speed, improve the torque, matching inertia. Planetary speed reducer of the highest rated input speed can reach 18000rpm (with the size of the reducer itself, the greater the speed reducer, the smaller the nominal input speed), the operating temperature is generally around -25 to 100 C, by changing the grease can change its operating temperature. Precision planetary reducer for collocation servo motor so back gap grade (ARC) is very important. Different backlash grade price difference is quite large, planetary reducer can do more gear box link maximum deceleration ratio of 1 00000.
Gear reducer gear transmission speed is not more than 10 m / s. Input shaft rotation speed is not higher than 1500 rpm / min. Working environment temperature of the reducer -+45 -40. The speed reducer can be used for positive and reverse two to run.
Q1: I want to buy your products, how can I pay? A: You can pay via T/T(30%+70%), L/C ,WEST UNION ,ESCROW etc. Especially ESCROW, which is guaranteed by Alibaba.com. It is safe and effective. Q2: How can you guarantee the quality? A: One year's warranty against B/L date. If you meet with quality problem, please send us pictures or video to check, we promise to send spare parts or new products to replace. Our guarantee not include inappropriate operation or wrong specification selection. Q3: How we select models and specifications? A: You can email us the series code (for example: R series helical gearbox) as well as requirement details, such as motor power, output speed or ratio, service factor or your application...as much data as possible. If you can supply some pictures or drawings, it is nice.
Q4: If we don’t find what we want on your website, what should we do? A: We offer three options: 1, You can email us the pictures, drawings or descriptions details. We will try to design your products on the basis of our standard models 2, Our R&D department is professional for OEM/ODM products by drawing/samples, you can send us samples, we do customized design for your bulk purchasing. 3, We can develop new products if they have good market. We have already developed many items for special using successful, such as special gearbox for agitator, cement conveyor, shoes machines and so on. Q5: Can we buy 1 pc of each item for quality testing? A: Yes, we are glad to accept trial order for quality testing Q6: How about your product delivery time? A: Normally for 20'container, it takes 25-30 workdays for worm and cycloid gearbox, 35-40 workdays for helical bevel gearbox,40-60 days for planetary gearbox.
