Internal Helical Ring Gears
HM Manufacturing is a manufacturer of custom internal helical ring gears produced to meet all your specifications and requirements. HM gears, are a reliable product to transmit power and to change the speed, torque, and direction of a power source for all your individual applications and needs. Our highly experienced team and state of the art facility allow for high volume production runs, prototypes and above all, quality gears. Our modern inspection department and quality control methods assure all products conform to your standards and are made to optimize production.
At HM we produce helical gears, spur gears, chain gears, internal gears and pawl & ratchet gears. Custom Gears can range in size from 3/4”-24” and are available in multiple pressure angles.
Helical gears are cylindrical gears with a slanted tooth trace. They are quieter and smoother because of less vibration when in play. As a result of the way the helical gears are shaped, the helical gear is most efficient in projects with a high power to weight ratio. Helical gears are great for replacing spur gears in an application where more power is required, such as automotive.
Internal Helical Gear
The internal gear has teeth machined on the interior surface of the gear. Internal gears are made for applications involving planetary gear drives and gear couplings since these gears have the ability to work on the inside of another gear. Our internal gears are made for tight tolerance applications with high precision. Internal gears are used in applications that require better load carrying capability due to its strong and effective shape. Internal gears are greatly used since they have reduced sliding action which improves gear longevity and tool life.
HM Manufacturing Order Processing Advantages
We encourage our customers to place 12 month blanket purchase orders to accommodate for annual requirements. This in turn allows us to hold materials exclusively for our customer and can usually be dispatched within one business day.
