Zhejiang Boqiang Transmission Co., Ltd. was established in 2002 and is a high-tech enterprise that integrates design, development, manufacturing, and operation, producing and selling reduction motors and power transmission equipment. The company is located in Oubei Town, Yongjia County, at the forefront of national reform and opening up, known as the "Little Pudong" of Wenzhou. Close to National Highway 104 and east to Wenzhou International Airport and Longwan International Container Terminal; South to Wenzhou Railway Station and Passenger Transport Center; There are also many national tourist attractions such as Yandang Mountain and Nanxi River. With convenient transportation and unique geographical location, it is highly welcomed by domestic and foreign users.
Our company produces twelve series of helical gear reducers for various purposes, including shaft mounted helical gear reducers, helical bevel gear reducers, helical worm gear reducers, spiral bevel gear steering boxes, worm gear reducers, continuously variable transmissions, spiral elevators, and large gearboxes. The power coverage is 0.12-2000kw, with a reduction ratio of 1.25-30000. Various combinations, deformations, and specialized products can meet most industrial requirements. The R, K, F, and S series reducers adopt the modular design principle of unit structure, greatly reducing the types of components and inventory, and greatly shortening the delivery cycle. The components have strong universality and low maintenance costs.
Boqiang has a leading position in China in terms of technology level and product market share. The products are widely used in various fields such as metallurgy, light industry, packaging, medicine, petroleum, chemical industry, lifting and transportation, three-dimensional parking, printing and dyeing, elevators, wind power, etc. Boqiang Company has excellent performance. The transmission technology experts from the headquarters and numerous application engineers and after-sales service technicians from various regional offices provide you with rapid and comprehensive technical consultation and comprehensive services.
Looking back at the past and looking forward to the future, Boqiang has always been on the way forward, constantly improving and surpassing itself with high-quality products and comprehensive services, and winning the favor of the market and customers. We are willing to work together with people of insight from all walks of life to create a more brilliant tomorrow.

FAQ
Q1: I want to buy your products, how can I pay?
A: You can pay via T/T(30%+70%), L/C ,D/P etc.
Q2: How can you guarantee the quality?
A: One year's warranty against B/L date. If you meet with quality problem, please send us pictures or video to check, we promise to send spare parts or new products to replace. Our guarantee not include inappropriate operation or wrong specification selection.
Q3: How we select models and specifications?
A: You can email us the series code (for example: RC series helical gearbox) as well as requirement details, such as motor power,output speed or ratio, service factor or your application...as much data as possible. If you can supply some pictures or drawings,it is nice.
Q4: If we don't find what we want on your website, what should we do?
A: We offer three options:
1, You can email us the pictures, drawings or descriptions details. We will try to design your products on the basis of our
standard models.
2, Our R&D department is professional for OEM/ODM products by drawing/samples, you can send us samples, we do customized design for your bulk purchasing.
3, We can develop new products if they have good market. We have already developed many items for special using successful, such as special gearbox for agitator, cement conveyor, shoes machines and so on.

Though reducer efficiency may vary slightly from one manufacturer to another, the way in which the gears intersect and mesh mainly determines speed reducer efficiency. This efficiency ranges from 49 to 98%, depending on the type of reducer and number of reduction stages it contains, Figure 1. Here’s a brief description of some common types and their relative efficiencies.
Worm gear. In these widely used speed reducers, a worm gear drives a worm wheel to provide output motion at a right angle to the motor shaft, Figure 2. The worm gear and worm wheel have non-intersecting, perpendicular axes, and the meshing action between gears occurs over a relatively large contact area. This meshing action consists primarily of a sliding motion that creates friction between the gears.
Efficiency of a worm-gear speed reducer depends (in part) on its speed-reduction ratio. High-ratio units have a smaller gear-tooth lead (helix) angle, which causes more surface contact between them. This higher contact causes higher friction and lower efficiency. Typical worm-gear efficiencies range from 49% for a 300:1, double-reduction ratio, up to 90% for a 5:1, single-reduction ratio. For this reason, these units are usually more suitable for low ratios.

Helical worm. The arrangement of gear stages in a speed reducer also affects its efficiency. In helical-worm speed reducers, a set of helical gears connected to the motor shaft drives a worm-gear set, Figure 3. The helical-gear set reduces input speed (from the motor) to the wormgear set. This keeps the worm-gear reduction ratio (and size) low to maximize its efficiency.
The combined efficiency of helical and worm gears ranges from 79% for a 300:1 speed-reduction ratio to 90% for a 5:1 ratio.
Helical bevel. As with worm and helical- worm units, the output shaft of this reducer type is at a right angle to the motor shaft, Figure 4. And like helical-worm speed reducers, a set of helical gears usually makes the first speed reduction.
Here, spiral-bevel gears are mounted with intersecting axes, an arrangement that minimizes friction between the gears to provide 94 to 97% efficiency.
The primary drawback to helical-bevel speed reducers is their higher cost than worm-gear units, especially for small ratios such as 5:1 or 10:1. But the added cost is sometimes offset in high-reduction- ratio units because their high efficiency allows the use of either a smaller reducer, motor, or both.
In-line helical. These speed reducers are often the best value for applications in which the motor and reducer are coupled in-line with the driven shaft, Figure 5. Their efficiency usually ranges between 95 and 98%, regardless of speed ratio. Cost is competitive with worm-gear speed reducers where the center distance is 2-in. or more.
Helical-gear sets have parallel axes between gear teeth and small contact areas, which keeps power-robbing friction and heat low.
To compare differerent types of speed reducers, first calculate the required load for your application and the efficiencies of the reducers being considered.
Load requirement. The key to proper speed-reducer selection is to determine the actual torque or power required to drive the load. First measure the torque (lb-in.) or power (hp) needed to drive the load at its input shaft.
Next, multiply the torque or power value by appropriate service factors to compensate for unusual operating conditions such as shock loads, frequent stopping and starting, and high temperature. These service factors are normally listed in manufacturers’ catalogs. The American Gear Manufacturers Association (AGMA) also publishes service factors for different classes of service in their standards.
For example, if a driven equipment shaft requires 2 hp, and it’s subject to moderate shock loads, apply a 1.4 service factor. If the ambient temperature is between 100 and 115 F, use a 1.15 service factor. Thus:
