Helical Gearbox

The helical gearbox is a low-power consumer and is compact. This equipment is used for a broad range of industrial applications, but typically in heavy-duty operations. The helical gearbox is popular in constructing plastics, cement, rubber, and other heavy industrial settings. It is helpful in crushers, extruders, coolers, and conveyors, all low-power applications. The helical gearbox is unique in that it is fixed at an angle that, when in motion, enables more teeth to interact in the same direction.

“Dedicated to Helical Gearbox Excellence.We also have a large onsite stock of replacement parts for our helical gearboxes and helical bevel gearboxes which can be shipped out whenever the need arises.”

Advantages of Helical Gearbox

Due to the thrust forces and increased sliding friction between components, the helical gearbox performs at lower efficiencies than spur types.
The angled teeth engage more gradually than spur gear teeth so that they can run more smoothly.
A helical gearbox, as well as helical gears, is mostly durable and perfect for high-load applications.
It has the potential to transfer power and motion between either right or parallel angle shafts.

Applications of Helical Gearbox

Most of the reputable industrial gearbox manufacturers propose helical gearbox to operate under heavy power efficiency, Some of them include Steel, rolling mills, and power, and port applications.
In addition to the above applications, there are many other uses. For example, printing industry, fertilizer industry, earth-moving industry, plastics industry, textile industry, food industry, elevators, conveyors, compressors, blowers, petroleum industry, etc.

K series

helical gearbox

The K series helical gearbox adopts the direct connection mode of the motor, and the structure is a first-stage helical gear plus a first-stage helical gear transmission. The output is shaft mounted and comes in six basic mounting styles. It can be reversed and reversed. The helical gear adopts a hard tooth surface, stable operation, large carrying capacity, and working environment temperature of -10 °C ~ 40 °C. Compared with similar effects, this product has a significant speed variation range, compact structure, and convenient installation. It can be widely used in metallurgy, mining, lifting, light industry, chemical, transportation, construction, and other mechanical equipment speed reduction mechanism.
Installation location selection
When possible, do not use a vertical installation. When installing vertically, the amount of lubricating oil added is much more than that of horizontal installation, which may cause heat generation and oil leakage of the gearbox.

Lubrication maintenance
The gearbox can be maintained according to the “five-set” principle of lubrication work. Every gearbox has a responsible person to check regularly and find that the temperature rise is obvious. If the temperature exceeds 40°C or the oil temperature exceeds 80°C, the quality of the oil will drop or oil. When more copper powder is found and abnormal noise is generated, stop using it immediately, repair it in time, troubleshoot it, and replace the oil. When refueling, pay attention to the amount of oil to ensure that the gear unit is properly lubricated.

Gearbox Characteristic:

(1) Space-saving, reliable and durable, with high overload capacity and power up to 132KW;

(2) Low energy consumption, superior performance, R series helical inline Coaxial helical inline gearbox efficiency as high as more than 95%;

(3) Low vibration, low noise, high energy saving;

(4) Select high quality forged steel materials, steel cast iron box body, and gear surface through high-frequency heat treatment;

(5) After precision processing, to ensure the shaft parallelism and bearing positioning requirements, the gearbox is forming the helical gear transmission assembly is equipped with various types of motors, which are combined into electromechanical integration, ultimately guaranteeing the product quality characteristics.

Why HEPT Helical Gearboxes?

The HEPT Helical Gearbox is not only durable but also extremely efficient. They are ideal to be used for applications with high loads. The load is evenly distributed amongst the axes, which reduces the risk of damaging the product. We are one of the leading Helical Gearboxes suppliers in China. With our expertise and experience, we ensure to deliver the best quality products to our customers. The Helical Gearboxes are the highest output torque, which allows them to enable precise positioning and movements. The long life of the gearbox ensures a longer service life as well.


Some FAQ

Q: How to choose a gearbox that meets our requirements?

A: You can refer to our catalog to choose the gearbox or we can help to choose when you provide the technical information of required output torque, output speed and motor parameter,s etc.

Q: What information shall we give before placing a purchase order?

a) Type of the gearbox, ratio, input and output type, input flange, mounting position, and motor information etc.

b) Housing color.

c) Purchase quantity.

d) Other special requirements.

Q: How to maintain the gearbox?

A: After a new gearbox is being used about 400 hours or 3 months, the lubrication needs to be changed. Afterthat, the oil changing cycle is about every 4000 hours; please do not mix-use different brands of lubrication. It should keep enough amount of lubrication in the gearbox housing and check it regularly. When it is found that the lubrication is deteriorated or the amount is decreased, the lubrication should be changed or filled up in time.

Q: What should we do when the gearbox is breakdown?

A: When the gearbox is breakdown, do not disassemble the parts first. Please contact the relative sales representative at our Foreign Trade Department and provide the information shown on the nameplate, like gearbox specification ans serial number; time used; fault type as well as the quantity of problemed ones. Finally take the appropriate action.

Q: How to store the gearbox?

a) Protected against rain, snow, humidity, dust and impact.

b) Place wood blocks or other material between the gearbox and ground.

c) The opened but not used gear units should be added with the anti-rust oil on their surface, and then return back to the container in time.

d) If the gearbox has been stored for 2 years or even longer time, please check the cleanliness and mechanical damage and whether the anti-rust layer is still there during the regular check-up.

Q: What should we do when unusual and even noise occurs during the gearbox running?

A: It is properly caused by the unevenly mesh between gears or the bearing is damaged. The possible solution is to check the lubrication and change bearings. Moreover, you can also ask our sales representative for further advise.
