SEW style's S series 90 degree shaft gearbox with motor worm gear reducer

Specifications

1.Pass ISO9001:2008, SGS
2.Capacity: 12000pcs per year.
3.low noise, excellent efficiency

- Structures: foot-mounted, flange-mounted, hollow shaft output or solid shaft output, with or without motor, with torque-arm lever, shaft-input type for sprocket or pulley;

 

- Has self-locking function like backstop;

 

- Modularization design: parts of gearbox owns high exchangeability, coupling between gearbox and motor is standardized(usually IEC standard);

 

- Transmission ratio: fine division, wide scope, and may combine different series to get larger ratio;

 

- Worm wheel made of high-quality Tin Bronze ZCuSn10Pb1, output shaft made of high-quality low-carbon alloy steel 40Cr, the gearbox housing made of high-strength casting iron HT250, may also adopt material as requested;

 

- High efficiency up to 98%per stage, low noise <60-70dB, and temperature rise <45-55°C;

 

- Gears and gear shafts through carburizing and quenching then fine profile grinding process, gearbox housing through aging treatment then annealing to relieve stress twice, therefore the bearing capacity very high;

 

- Best China bearings used on products, may apply other bearings like SKF, NSK and FAG, and double-lip oil seal make sure no oil leak;

 

- May custom different models according to clients' requirement;

 

- Every gearbox 100 percent tested prior to delivery.
