This guide helps plant owners and maintenance heads in Hanumangarh Junction, Hanumangarh Town, Nohar, Bhadra, Pilibanga, Rawatsar, Sangaria and Tibbi choose the right gearbox, avoid common sizing mistakes and know what to ask a manufacturer. Our works follow ISO 9001, ISO 14001 and ISO 45001 systems.
Who is a helical gearbox manufacturer for Hanumangarh plants?
A helical gearbox manufacturer for Hanumangarh should do more than sell a catalogue unit. It should check the load on the driven machine, the starts per hour and the daily running hours, then pick a ratio and frame size with enough margin. R K Engineering Works does this sizing for every order and supplies the gearbox with a test report and a fitting drawing.
- Helical inline gearboxes for conveyors, bucket elevators, mixers and screw feeders.
- Helical bevel (right-angle) gearboxes where space is tight and efficiency still matters.
- Worm gearboxes for compact right-angle drives, gates and light-duty machines.
- Crane and winch gearboxes for hoist, cross travel and long travel drives.
Helical vs worm gearbox: which one fits your drive?
Agro-processing plants in Hanumangarh run long seasons with dust and summer heat. The table below compares the two common gearbox types on the points that matter most in these plants.
| Point | Helical gearbox | Worm gearbox |
|---|---|---|
| Efficiency | High, less power lost as heat | Lower, more heat at high ratios |
| Shaft layout | Inline or right-angle (bevel helical) | Right-angle only |
| Running hours | Suits long shifts and seasons | Suits short or medium duty |
| Heat in summer | Runs cooler | Needs care with oil and cooling |
| Size for same torque | Larger at high ratios | Compact |
| Typical use | Conveyors, elevators, mixers, crane drives | Gates, small feeders, light machines |
If your drive runs most of the day during the ginning or milling season, a helical gearbox is usually the safer choice. If the drive is compact, runs only a few hours and needs a right angle, a worm gearbox can work well.
Gearbox spec sheet: what to send before design
| Detail | Why we need it |
|---|---|
| Motor power (kW or HP) and motor speed | Sets input torque and frame size |
| Required output speed | Sets the gear ratio |
| Driven machine and type of load | Sets the service factor (smooth, medium or shock load) |
| Hours of running per day and starts per hour | Sets gear life and heat checks |
| Mounting: foot, flange or shaft-mounted | Decides housing design |
| Shaft sizes, shaft height and direction of rotation | Lets the new unit fit the old base |
| Site conditions: dust, heat, outdoor use | Decides seals, breather and oil grade |
How to choose the right gearbox in 6 steps
- List the drive: machine, motor power, speeds and running hours.
- Pick the type: helical for long running and high efficiency, worm for compact low-duty right-angle drives.
- Apply a service factor: higher for shock loads, frequent starts and long shifts.
- Check heat: make sure the gearbox can shed heat in a hot shed during summer.
- Match mounting: shaft height, shaft size and bolt holes to the existing base.
- Plan service: oil change interval, seal checks and spare parts list.
Common gearbox problems we see in Hanumangarh plants
- Undersized gearbox: chosen only on motor power, without a service factor, so gears and bearings wear early.
- Overheating in summer: wrong oil grade or a worm gearbox used on a long running drive.
- Oil leaks and dust entry: worn seals and blocked breathers in ginning and grain dust.
- Misalignment: the motor, gearbox and machine shafts not in line, which breaks couplings and bearings.

Frequently asked questions
Who is a helical gearbox manufacturer for Hanumangarh?
R K Engineering Works, Jaipur, designs and builds helical and worm gearboxes for plants in Hanumangarh, Nohar, Bhadra, Pilibanga, Rawatsar, Sangaria and Tibbi. Each gearbox is sized from motor power, output speed, torque and hours of running per day.
Helical or worm gearbox: which is better for a cotton ginning or oil mill drive?
For conveyors, elevators, mixers and long running drives, a helical gearbox is usually the better choice because it runs cooler and wastes less power. A worm gearbox suits compact right-angle drives with low to medium running hours.
What details do you need to size a gearbox?
Send the motor power and speed, the required output speed, the driven machine, the mounting position, the shaft details and the hours of running per day. A photo of the old gearbox name plate also helps.
Can you replace an old gearbox of another make?
Yes. We take the dimensions of the old unit and match shaft height, shaft size and foot or flange mounting, so the new gearbox fits the same base with little or no change.
हनुमानगढ़ में हेलिकल गियरबॉक्स निर्माता कौन है?
आर के इंजीनियरिंग वर्क्स, जयपुर हनुमानगढ़, नोहर, भादरा, पीलीबंगा, रावतसर और संगरिया के प्लांट्स के लिए हेलिकल और वर्म गियरबॉक्स बनाता है। हर गियरबॉक्स मोटर पावर, आउटपुट स्पीड, टॉर्क और रोज़ के चलने के घंटों के अनुसार चुना जाता है।
क्या पुराने गियरबॉक्स की जगह नया गियरबॉक्स उसी बेस पर लग सकता है?
हाँ। हम पुराने गियरबॉक्स की शाफ्ट ऊँचाई, शाफ्ट साइज़ और माउंटिंग नापकर नया गियरबॉक्स बनाते हैं, ताकि वह उसी बेस पर कम बदलाव के साथ लग सके।
