General Survey

ZLYJ Serial Gearboxer for Plastic and Rubber Single Screw Rod Extruder is a kind of special reducer researched and developed by the most advanced technology of the hard teeth-surface in the world. For recent ten years, they are widely used in top and middle grade plastic, rubber and chemical fiber extruders, sell well in the country and are exported abroad. With a higher reputation in the industry, it has features as follows:

1. The whole machine looks beautiful and liberal, and can be used both vertically and horizontally. It can suit multiple requirement of assembling.

2. The gear data and box structure are optimally designed by the computer. The gears are made of top grade low carbon

alloy steel with Grade 6 precision of teeth after carbon penetrating, quench and teeth grinding. The hardness of the

teeth surface is 54 - 62 HRC. The gear pair has stable running, low noisy and has high driving efficiency.

3. The assembling connector has the precision of radial run-out and end face run-out at international level, and can be

easily connected with screw rod of the machine barrel.

4. The bearing structure of the output shaft has a unique style, which can effectively prolong service life of the bearings.

5. All standard parts such as bearing, oil seal, lubricant oil pump etc. are all top quality products selected from domestic

famous manufacturers. They can be also selected from imported products as per requirement of customer.

Applicable Range

1. This serial product can be used in reducing driving of single screw rod extruder with the screw rod diameter of 30 - 250mm.

2. The input speed of the gearboxer is normally not larger than 1500 rpm.

3. The driving ratio is between 6.3 and 20, and that in the table can be selected preferentially. The driving ratio can be

also adjusted as per requirement of customer.

4. The temperature in work environment is -10℃ ~ 45℃. When temperature is lower than 0℃, the lubricant oil should be

preheated before starting.
