| About | Design Ideal & Features of Gear Reducer Design Ideal: Our company has been spending more than 30 years on gear reducers by adopting the latest technology of gear design software to provide high strength and top precision gear elements. We also import top precision equipment from abroad. All products are finished under perfect inspection and quality control. Our clients include steelworks, paper mills, rubber plants, textile factories and factories of heavy horsepower and overload. We try our best to perform our perfect service. Features of Gear Reducers: (1) Gear elements of reducers adopt low-carbon alloy steel bars, and are forged and positively treated so as to increase internal texture compactness of the object and strengthen tenacity. (2) Gear elements of reducers adopt a special 25 degree pressure angle tooth form. Because of thick root, the elements can bear more loads and more impact. (3) After the gear elements of reducer are treated through permeated carbon, tooth surface is polished through top precision gear grinder so as to increase engagement of teeth surface, reduce noise, raise working efficiency, and prolong gear reducer life. Gear elements of reducers meet the standard of AGMA. Because of thick root, the elements can bear more loads and more impact. Gear Couplings DA YI gear couplings are suitable for steel, iron, rubber, plastic, chemical engineering, cable, and general heavy machines in high-load horse-power factories. Now, customers use our couplings get the fullest satisfaction. Distinctive Features of DA YI Gear Couplings: 1. DA YI gear couplings, shaved by precision machines, are crowned in order to increase flexibility. For the short tooth profile, a stub tooth with pressure angle of 200 is adopted. The tooth top is rounded in contrary angle in order to permit larger error in shafts and higher loads in revolving condition. 2. DA YI gear couplings are given the special hardening treatment on the tooth surfaces to enable them to have the strongest intensity and resisting-grind. So, the tooth surfaces can receive operation in larger loads and connection in shaft rotating at relatively high speeds. 3. DA YI gear couplings are the closed couplings for easily lubricated and usually keep the tooth surfaces in appropriately oil. So, they not only prevent dust from going and oil leakage, but also prolong life of couplings. 4. The type of DA YI gear couplings has been successful done in the first processing. It must be done in the second procedure of heat treating again according to material. It was given more rigidly precision, increasing tenacity. At last, we remove the gravitation by striking-ball bearing when those steps are all finished. Characteristics of Pro-Flex Couplings: 1. No Lubricant Is Needed Because of no slide and friction, lubricant is not needed. There is no noise and abrasion. 2. No Maintenance. Install and Forget It. 3. Not Heavy; High Torsional Moment Distinguish by operation. There are a broad range of selections to replace materials by aluminum alloy so as to reduce weight. 4. Allowable for More Errors 5. Usable in High Temperature 6. No Rear Gap & Forceful Torsional Strength It is most suitable for machines requiring correct shaft revolution and phase control. 7. Usable in High Speed Occasion Because of no rear gap and lightweight, balance is good. 8. Simple Installation Because of small quantity of components in compact size, assembly and disassembly can be rapidly done. 9. Tough Structure & High Safety Factor Because load stress maintains at a lowest standard, it can produce high safety factors. 10. Automatic Protective Devices If elements wear and tear, an automatic protective device will pass the washer to revolve. |
