SD-BR Hollow Shaft Reducer Series
High-precision SD reducer can be applied to many industry fields, such as: medical equipment, machine tools, automatic machining equipment, national defense science and technology, information navigation, mechanical equipment, semi-conductor industry,
As for the SD reducer technology, it over-turns traditional design principles of gear-reduction for centuries. After carefully design, R&D, trial-manufacture, test and improvement, the core components of SD reducer have solved some main problems, such as: processing technology, material selection, and so on. High-precision SD reducer can meet the requirement of all industrial field, even if it is highest requirement.
Using movable gear transmission technology， steel balls are used to replace the traditional fixed gear teeth， through preloading and cycloid raceway to form a gap-less rolling mesh pair, to achieve zero backlash, high precision.
■No dead ends
Cycloidal motion trajectory, to achieve all-round operation without dead angle.
■Large hollow shaft
The extra-large hollow shaft is ideal for the cables, pipelines, various shafts to pass through the axis of rotation. This structure is suitable for applications such as timing belts, which effectively saves the space.
The output adopts cross-roller bearing (or double row angular contact bearing) , and all the steel balls are engaged in meshing transmission with high contact degree, with high bearing capacity and overload capacity.
Transmission Meshing Mechanism belongs to rolling contact mode, no impact, low operating noise.
Using differential transmission, the maximum speed ratio of the first stage can reach several hundred, through the corresponding combination, it can reach several thousand, covering a wide range of speed ratios.
The steel ball and the cycloid raceway adopt rolling contact meshing, effectively reduces the friction resistance in operation, thus the transmission efficiency is high.
The reducer adopts a closed structure and is filled with high-viscosity, anti-corrosion, anti-wear, water-resistant, medium-resistant and anti-oxidant grease, which can effectively prevent oil leakage, and there is no need to supplement or replace grease during the life of the product.
The installation posture has no limitation, and has more convenient design freedom.
■Long service life
The rolling friction transmission method is adopted to effectively reduce the temperature rise and wear during operation, and the design life is long.
Can work with any motor through appropriate connection methods, to meet various demands and needs in different environments and locations.
High-precision SD reducer can be applied to many industry fields, such as: medical equipment, machine tools, automatic machining equipment, national defense science and technology, information navigation, mechanical equipment, semi-conductor industry, automation industry, industrial robot, new energy industry, photo-voltaic power plant, wind power industry, and so on.
