Product details

一、Product Description

These custom precision helical gears are manufactured from 42CrMo alloy steel, a material prized for its excellent hardenability, impact strength, and wear resistance. They are ideally suited for high-speed, heavy-load power transmission applications, capable of withstanding continuous alternating loads without tooth breakage or deformation. Two surface finish options are available: black oxide coating (providing rust protection for humid environments) or an untreated raw finish (facilitating subsequent heat treatments such as quenching or carburizing). We offer professional OEM customization, adjusting parameters—such as module, helix angle, tooth count, face width, and bore specifications—based on customer drawings to suit gearboxes, transmission mechanisms, and automated powertrains. As high-quality OEM helical gears, they feature strictly controlled tolerances for tooth profiles and bore fits, ensuring smooth meshing and reduced transmission noise. Balancing toughness and strength, these 42CrMo helical gears are an excellent choice for heavy-duty transmission systems.

二、Key Specifications

Product Name: Helical Transmission Gear

Material: 42CrMo Alloy Steel

Surface Treatment: Black Oxide Finish

Product Characteristics: High strength and impact resistance; wear and fatigue resistance; smooth, low-noise operation; suitable for subsequent heat treatment

Applications: Gearbox components, automated transmission modules, construction machinery drive units, precision power output mechanisms

三、Machining Process

42CrMo alloy steel bar stock is cut to size, and Turning Services are used to perform rough turning of the gear blanks to form the outer diameter and inner bore reference surfaces. The gear reference end face and assembly bore are precision-turned using Precision CNC Turning Services, with strict control over coaxiality and roundness tolerances; the turned semi-finished products are classified as precision CNC turned parts. Subsequent processes include gear hobbing and milling to form helical tooth profiles, followed by deburring; blackening treatment is applied as per customer requirements. All workpieces undergo tooth profile inspection and dimensional verification to ensure meshing accuracy and assembly interchangeability for batch-produced parts.

四、Company Profile

Dongguan Shengpeng Precision Technology Co., Ltd. operates as both a manufacturer and a trader, specializing in the OEM customization of various alloy steel power transmission components. The factory is capable of mass-producing non-standard gear components—such as helical gears—offering customization options for module sizes, materials, and surface finishes, alongside integrated heat treatment services like quenching and blackening. We handle orders of all sizes, leveraging mature alloy steel processing techniques, flexible customization solutions, and a robust export delivery system to provide global manufacturers of power transmission equipment with one-stop, precision-engineered component solutions.
