Parallel Shaft Reducer
Engineers love the parallel shaft reducer because it makes such a great workhorse for high-torque applications. When selecting a parallel shaft reducer for an industrial setting, however, there are a variety of conditions that can affect the drive size and auxiliary equipment required. For example:
Sun exposure. If the parallel shaft drive will be operated outdoors in the sun, at ambient temperatures higher than 100 degrees Fahrenheit, then pains will need to be taken to protect the drive from the sun – specifically, the sump temperature must not be allowed to exceed 200 degrees Fahrenheit. Often painting the drive with reflective paint or erecting a simple canopy to provide shade will suffice. In some situations, a heat exchanger or other cooling equipment may be needed.
Reversals. If the parallel shaft reducer will be used for an application requiring more than 20 reversals in a 10-hour period – or if the reversals involve peak torques larger than 200 percent of the normal load – consult the manufacturer or supplier before selecting a drive.
Brake-equipped applications. If the parallel shaft reducer will be equipped with a brake between the gear drive and the prime mover to decelerate the system, this should be taken into account during the selection process. Consult the manufacturer to determine the proper drive rating.
Excessive, overhung or thrust loads. If the application at hand will involve any of these types of loads, extra care must be taken to select a drive that is properly rated to handle them.
These are just a few of the special conditions to keep in mind when choosing a parallel shaft reducer. When in doubt, consult a quality supplier such as Mar-Dustrial, whose expert technicians can help you make the right decision.
