A rack and pinion steering system consist of a pinion (a circular gear) with a rack (a linear kit). The system works by converting a revolving motion into a linear motion. Most cars, small trucks, and SUVs come equipped with a rack and pinion system, rather than the recirculating ball steering found in larger trucks, larger SUVs, and other heavy-duty vehicles.

Instruction of Rack Assembly

To assemble connected racks more smoothly, 2 ends of a standard rack would add half tooth which is convenient for next half tooth of next rack to be connected to a complete tooth. The following drawing shows how 2 racks connect and tooth gauge can control pitch position accurately.
With regards to connection of helical racks, it can be connected accurately by opposite tooth gauge.
1. When connecting racks, we recommend lock bores on the sides of rack first, and lock bores by the sequence of the foundation. With assembling the tooth gauge, pitch position of racks can be assembled accurately and completely.
2. Last, lock the position pins on 2 sides of rack; the assembly is completed.

Advantages of rack and pinion transmission

(1) Large transmission power

(2) Long life, stable operation and high reliability

(3) It can ensure a constant transmission ratio and can transmit motion between two shafts at any included angle

Gear Rack Application

mainly used in various mechanical transmission systems, like Automation Machine, CNC Machine, Building Material Shops, Manufacturing Plant, Machinery Repair Shops, Construction works and so on.
