用于自动化的塑料齿条设计
Engineering context Automation racks should be designed around the motion profile and installation support. Rapid reversals, long travel and positioning requirements can expose rack joint, straightness and backlash…

Plastic Rack and Pinion Selection
Start from the mechanism Rack-and-pinion selection combines tooth geometry with the way the rack is supported over its travel. Module/DP and pressure angle define the mesh, while rack…
Read articlePlastic Internal Ring Gear Design
Frame the problem correctly Internal ring gears are sensitive to concentricity, wall stiffness and the geometry of the mating pinions or planets. The internal teeth share a common…
Read articlePlastic Spur Gear Design Inputs
What changes the engineering choice A spur gear RFQ should define the complete working mesh, not only outside diameter and tooth count. Module/DP, pressure angle, face width, bore,…
Read articlePlastic Helical Gear Design Inputs
Decision first Helical gear drawings must make the helix convention unambiguous. Helix angle, hand and the normal/transverse system affect mating compatibility. Helical gears also generate axial load that…
Read articleMC Nylon Gear Selection Guide
Engineering context MC nylon is often considered for larger machined gears, but dimensional conditioning and the operating environment need explicit review. Cast nylon stock can be machined into…
Read articlePOM Gear Selection Guide
Start from the mechanism POM gear selection should start with service conditions and mating geometry, then narrow to a resin grade and process. POM grades vary in viscosity,…
Read articleInjection Molded Bevel Gear Selection
Frame the problem correctly An injection molded bevel gear should be selected around its mating gear, moldability and assembly datums. Bevel teeth, hub geometry and wall sections need…
Read articlePlastic Bevel Gear Design Inputs
What changes the engineering choice Bevel gear design begins with the pair geometry and the intersecting shaft layout. Ratio, shaft angle, pitch-cone geometry, face width and mounting distance…
Read articlePlastic vs Metal Gears
Decision first Plastic and metal gears solve different design priorities; neither is automatically superior. Engineering plastics can reduce mass, resist corrosion and run with different noise/lubrication behavior, while…
