DIN 3961 Standard Heavy-Duty Straight Gear with Hardened Teeth for Machinery

Product Overview

Core Features

• Strict DIN 3961 Standard Compliance: Every production and inspection procedure follows DIN 3961 industrial gear dimensional and precision standards. Key indicators such as gear module, tooth pitch, runout tolerance and meshing clearance are precisely calibrated to meet European industrial universal specifications. The standardized design ensures perfect compatibility and interchangeability with DIN-standard gearboxes and mechanical systems, eliminating assembly errors and specification mismatches for overseas and standard machinery projects.

• Hardened Tooth Surface for Extreme Durability: Undergoes professional tooth surface quenching and hardening treatment, forming a high-hardness wear-resistant layer on the gear tooth while retaining tough inner core structure. This optimized dual-performance design effectively resists long-term meshing friction, abrasive wear and instantaneous impact load, preventing common failures like tooth surface peeling, abrasion and tooth breakage under continuous heavy-duty operation.

• Stable Heavy-Duty Straight-Tooth Transmission: Classic straight gear structure features complete tooth surface contact and uniform force bearing during meshing. It provides direct, high-efficiency torque transmission with no power loss or delayed response, perfectly suited for heavy machinery scenarios requiring large bearing capacity and stable power output. The simplified meshing structure also reduces mechanical failure points for more reliable long-term operation.

• Precision Industrial-Grade Machining: Adopts advanced CNC hobbing and fine finishing technology to process each gear tooth with smooth surface and accurate tooth profile. Strict finished-product sampling inspection ensures minimal dimensional deviation and stable meshing accuracy. It maintains consistent transmission precision and smooth operation even after long-cycle high-frequency mechanical operation.

• High Structural Rigidity & Deformation Resistance: Made of high-purity industrial steel with integral one-piece forming technology, the gear body boasts excellent torsional resistance and structural stability. It can withstand continuous heavy pressure, alternating load and frequent startup impact without deformation or cracking, fully meeting the rigorous durability requirements of industrial heavy machinery.
