Rack Gear And Pinion Gear

Rack Gear And Pinion Gear:

Features of gear transmission mechanism:

Gear mechanism is the most widely used transmission mechanism in modern machinery, which is used to transfer the motion and power between any two or more shafts in space.

Generally, the coincidence degree of matel rack and pinion meshing is greater than 1, which can be meshed continuously (much better than that of gear and gear). As long as the gear does not produce undercutting, etc. 

The minimum number of teeth of standard spur gears is 17. When the matel rack and pinion moves to the limit position on one side, it can "enrich" two teeth on the other side.

Rack processing equipment: gear hobbing machine, CNC machine tool, gear shaper, lathe, gear grinder, milling machine, gear shaving machine, gear planer, wire cutting, etc. The higher the precision requirements of rack products, the higher the requirements of processing equipment used, and the purchase cost is much higher.

Metal gear rack processing method: generation processing and profiling processing, including gear shaping, gear hobbing, gear grinding, gear honing and gear shaving.

The metal gear rack is a strip-shaped part that matches the gear. It is equal to a section of the circumference of a gear with infinite diameter. There are many teeth evenly distributed on one side, which mesh with the gears to change the rotation into movement, or change the movement into rotation. The rack is a long strip with teeth on one side. It can be considered as a section of a gear with infinite diameter.

Parameter selection:

1. Whether the runout, full tooth depth, common normal line and tooth direction of the gear are qualified, and whether the one tooth swing error and circumferential pitch error exceed the tolerance.

2. Whether the installation distance of gear and rack is appropriate after installation.

3. The meshing clearance of rack and gear shall be 0.25* modulus.

4. Whether the full tooth depth, runout, common normal line, especially the tooth direction of the rack are qualified.
