GEARX/rack and pinion

Product catalog summary
Overview: The document is a catalog from Hebei GEARX Limited, focusing on gear transmission products, specifically gear racks. It includes detailed specifications for helical and straight gear racks, highlighting materials, treatments, and precision standards.
Helical Racks: This section outlines specifications for helical racks, detailing module sizes, dimensions, number of teeth, and material specifications. Materials include SCM440/42CrMo and S45C/C45, with treatments like induction hardening and quenching and tempering. Hardness ranges from HRC 18-55, and precision grades from DIN 6h25 to DIN 10e27.
Straight Racks: Specifications for straight racks are similar to those for helical racks, covering dimensions, material types, and treatments. Consistent materials and treatments ensure durability and precision.
Specifications and Standards: Each rack type includes specific pressure angles, helix angles, and surface finishes. Precision grade and permissible pitch error (Fp1000) are specified, indicating maximum deviation allowed over a 1000mm length.
Key Data from Tables: Tables provide detailed measurements for each rack type, including module size, length, width, height, number of teeth, and hole specifications. Total pitch error is specified to ensure accuracy and performance.
Critical Information: Emphasis is placed on material choice and treatment to achieve desired hardness and precision. The use of SCM440/42CrMo and S45C/C45 materials, along with specific heat treatments, ensures high standards of durability and performance.
Specifications: Racks are made from SCM440/42CrMo4 and C45 steel, quenched and tempered for enhanced durability. Tooth surfaces are milled or ground, with side surfaces ground on three or four sides, and end surfaces milled for linking. Precision grades range from DIN 6h25 to 10e27, with tooth surface hardness varying between HRC 18-55.
Dimensional Data: Lists various rack models with specific dimensions such as module, length, width, height, number of teeth, and hole specifications. Total pitch error (Fp1000) is provided, indicating permissible deviation in length per 1000mm.
Key Models: Includes MR Series (e.g., MR1-50Q, MR1.5-50QB, MR2-50QB) and SR Series (e.g., SR1-50G, SR1.5-50GB, SR2-50GB) with varying modules and dimensions.
