Product Description

Product Description

HELICAL GEAR

A helical gear is a type of cylindrical gear on which the teeth are helicoid, that has teeth that are cut at an angle to the axis of rotation. They are similar to spur gears but offer advantages both in torque capacity and smoothness of operations. Helical gears transmit power and motion between two parallel shafts.

Utilizing CNC turning, milling, and mill-turn processes, our gears achieve precise dimensions and surface finishes, ensuring optimal performance and efficiency in manufacturing, repair shops,s, and other industries.

AUTOMOTIVE INDUSTRY:

The automotive industry uses helical gears in the manufacturing of vehicle components. They are commonly used in transmission systems, steering systems, differentials, and power steering mechanisms. THelical gears help change the speed and graphics of the vehicle, ensure smooth and quiet operation, achieve precise steering, and transmit signals between the axles and wheels.

UNLOADING HANDLING AND LOGISTICS:

Helical gears are used in pipeline systems, forklifts, pallet trucks, and automated guided vehicles (AGVs) in the strict operation and logistics industries. They help adjust the speed box of the transported items, ensure smooth and quiet operation, and precisely control the handling of heavy goods. Forklifts and pallet trucks assist in the transporting, while AGVs help in tautomatically transports along the starting path.
 

MACHINE TOOLS AND MANUFACTURING EQUIPMENT:

In processing and manufacturing, helical gear reducers can be used in CNC machine tools, lathes, milling machines, drilling machines, etc. These machine tools achieve precision processing and molding by changing the speed and graphics of the workpiece. In addition, helical gears are also used in robotic arms, servos, and actuators, which are responsible for adjusting the speed and accuracy of graphic output and providing flexible movement and manipulation functions for robotic equipment.

AEROSPACE INDUSTRY:

In the aerospace industry, extensive gear evaluation is performed for aircraft engine stop boxes and satellite and spacecraft transmission systems. This allows the gears to bear more load and transmit power stably under harsh conditions.
 

PRODUCT QUALITY:

Users will have different needs in terms of gear noise, load, and voltage. Buyers should get decent-quality helical gears that suit different uses. The high-quality gears will work effectively and have a lengthy lifespan.

FAQ

Q1: What is the difference between helical and straight gears?
A1: The teeth in a straight gear pose an immediate impact, nicely aligning the driving and the driven wheel. Nonetheless, abrupt impacts result in noise and vibration in working circumstances. Conversely, the helical gear teeth are sloped, so they gradually engage with each other, producing a smooth and steady operation.

Q2: Why do people use helical gears?
A2: The helical gear was created to work more quietly than spur gears, transferring loads between parallel axes, among other advantages. Moreover, the first gear to enter operation creates a uniform and gradual tooth interaction due to its slanted teeth, which spreads the load across multiple teeth.

Q3: Can helical gears mesh with spur gears?
A3: If the size and tooth count are approximately identical, spur helical and spur gears can occasionally be used together. Nonetheless, the direct impact would result in more significant internal friction, noise, and gear deterioration.

Q4: Are helical gears stronger than straight gears?
A4: While helical and straight-cut gear teeth have their benefits and applications, helical teeth are stronger than straight teeth. This is because helical gears have more significant tooth engagement owing to their angled teeth. This results in a smoother transmission of power and better load distribution.

Q5: Do helical gears create more friction?
A5: Although helical gears have more tooth engagement, this results in smoother power transmission and less friction. Straight-cut gears tend to have point contact because of their parallel teeth, which could lead to more friction during power transmission.
