Brand Name	Lihao

Structure Features:
1.Single-Direction Bearing (made in Germany)
  Inlayed cemented carbide alloy which coordinates with roller bearing, featuring good abrasive resistance, safety, high accuracy and long service time.

Gears are processed through heating treatment HRC600 and then through high accurate grinding. Hence high driving accuracy.

2.Roller
Processed through heating treatment HRC600 and then through grinding; hollow structure, light in weight, weak gyration inertia, casual stop, and with high feeding accuracy; featuring high hardness, good abrasive resistance and long service span.

3. Disk Type Brake (common brake device)
Adopted high-quality clutch disk lining whose two faces interconnected completely, featuring long service span, good stability, and high accuracy.

4. Reversing Device:
(1) The structure is the same as that of single-way device.

It controls the lower gear with high accuracy and can maintain the lower wheel a long-time stability and high accuracy.
(2) The problem of the overturning of the lower wheel caused by sprayed oil when pressed is avoided.
(3) Not apt to cause high heat.
(4) With cemented carbide alloy and roller bearing, free of abrasion.
(5) That the roller bearing works in a circular motion way can avoid bearing seizure.
(6) It has weak frictional force and needs low torque fore. Its rotating drive is not apt to be damaged.
(7) The reversal device’s speed can reach to 30m/min, increasing 50% compared with common speed of 20m/min.
(8) Special structure is adopted to extend its service span.
