Horizontal open type
Product characteristics：
1. Using open base, the tooth surface is easy to maintain and reduce the cost of the whole machine.
2. Special machine tools are used to produce toroidal worm, which has multi tooth contact and can transmit large torque, and can bear greater axial force, radial force and overturning moment.
3. The product design adopts the general size at home and abroad, which will be replaced later.
Scope of application：
1. The product is mostly used in the relative rotating parts of construction machinery.
2. Aerial vehicle
3. Agricultural machinery
4. Truck mounted crane
5. Rotation of construction machinery chassis
Application advantages：
1. the surface of the product was treated by electrostatic powder spraying for two times, using epoxy zinc rich base powder and epoxy resin flour, greatly improving the corrosion resistance and aging resistance of the product, and neutral salt spray test for more than 1000 hours.
2. The raceway of slewing bearing and gear tooth surface are quenched, with high hardness and strong rigidity.
3. The service life can reach 25 years.
4. It has self-locking function and improves the safety of use.
5. The transmission accuracy can reach 1 milliradian (1mrad).
6. The product is developed based on the principle of maintenance free, with minimal maintenance.
7. The load and overturning moment of the product are greater than that of the similar products in the market.
8. The product has been tested at high and low temperature, and has strong resistance to temperature difference.
9. It adopts national high-tech graphene synthetic grease, whose service life and heat dissipation efficiency are far better than ordinary grease.
10. Toroidal worm design, multi tooth contact, bearing large output torque.
