2Pcs Set Bevel Gear 1.5 Mod 1:2 (15T/30T) 90 ° Pairing Heavy Duty Motor Metal Gear

Description

Product Overview

The HJZ-US 2-piece bevel gear set is engineered to meet the rigorous demands of modern industrial machinery. Each gear is manufactured from high‑grade 45 # steel, a material known for its excellent hardness, wear resistance, and ability to maintain dimensional stability under heavy loads. The set includes a 15‑tooth driver gear and a 30‑tooth driven gear, delivering a precise 1.5 Modulus and a 1:2 gear ratio that ensures smooth and efficient power transfer at a 90° angle.

Our bevel gears are designed with a 90° pairing configuration, allowing them to change the direction of rotation while preserving torque. This geometry is essential for applications such as motor shafts, gearboxes, and conveyor systems where space constraints require compact yet powerful solutions. The gears feature a standard tooth profile that minimizes noise and vibration, contributing to quieter operation and longer service life.

In addition to the robust material selection, the gears are heat‑treated to achieve a surface hardness of approximately 55‑60 HRC, providing superior resistance to pitting and surface fatigue. The precision machining process guarantees tight tolerances on pitch diameter, tooth thickness, and backlash, which are critical parameters for maintaining synchronization between mating gears.

While the gears do not include set screw holes, they are designed to be easily machined or tapped by the end user if custom mounting solutions are required. This flexibility allows engineers to adapt the gears to a wide range of shaft diameters and mounting configurations without compromising the integrity of the gear teeth.

Usage

The HJZ-US bevel gear set is ideally suited for heavy‑duty motor applications where reliable torque conversion and directional change are paramount. Typical use cases include industrial automation equipment, robotic arms, CNC machines, and agricultural machinery that demand consistent performance under high load conditions.

Because the gears are fabricated from 45 # steel, they can withstand harsh operating environments, including exposure to oil, coolant, and elevated temperatures. This makes them a reliable choice for equipment operating in manufacturing plants, processing facilities, and outdoor settings where durability is a key concern.

Engineers often integrate these gears into custom gearboxes to achieve specific speed reductions or to align motor shafts with driven components that are positioned at right angles. The 1:2 ratio provides a straightforward method for halving rotational speed while doubling torque, a common requirement in many power‑transmission scenarios.

Installation is straightforward for users familiar with standard machining practices. The gears can be pressed onto shafts, secured with set screws (if drilled), or bonded with high‑strength adhesives for applications where a permanent connection is desired. Proper lubrication with gear oil or synthetic grease further enhances performance and extends service intervals.

FAQ

What material is used for the gears and why is it suitable?

The gears are made from 45 # steel, a medium‑carbon alloy that offers a good balance of hardness, toughness, and machinability. This material is widely used in gear manufacturing because it can be heat‑treated to achieve a hard surface while retaining a ductile core, making it resistant to wear, pitting, and fatigue under cyclic loading.

Can these bevel gears be used with shafts of different diameters?

Yes. Although the gears do not come with pre‑drilled set screw holes, they can be easily machined or tapped by the end user to accommodate a variety of shaft sizes. This flexibility allows you to customize the mounting method—whether using set screws, keyways, or adhesive bonding—to suit the specific requirements of your equipment.

What is the recommended lubrication method for optimal performance?

For most industrial applications, a high‑quality gear oil with a viscosity appropriate for the operating temperature range is recommended. In environments with high speeds or heavy loads, synthetic greases can provide additional film strength and reduce wear. Regular lubrication intervals should be established based on the manufacturer’s guidelines and the operating conditions of the machinery.

How does the 1:2 gear ratio affect motor speed and torque?

A 1:2 ratio means the driven gear rotates at half the speed of the driver gear while delivering approximately double the torque, assuming negligible losses. This relationship is useful when you need to reduce motor speed for better control or increase torque to drive heavier loads without changing the motor itself.

What warranty and after‑sales support does HJZ‑US provide?

HJZ‑US offers a standard one‑year warranty covering material defects and workmanship. Our customer service team is available to assist with technical questions, installation advice, and any issues that may arise during the warranty period. We also provide replacement parts and repair services to minimize downtime for your operations.
