Use this form to request engineering assistance. The data you furnish will enable us to understand your application and recommend* the appropriate gearbox. When available, please attach prints or dimensional drawings.
*Recommendation is based on information supplied by the customer. Final acceptance and approval is the responsibility of the customer. Tolomatic recommends field testing or simulation of field testing on the machine it is designed for.
To determine the gearbox for your required torque: Reference the Torque and Efficiency charts from the product catalog or on www.tolomatic.com for the performance data for each model. Locate your input torque on the graph and intersect it with the RPM of the input shaft. In general, gearbox capacity increases as listed below:
For ratios other than 1:1: Refer to the performance graph for that gearbox. When torque vs RPM intersects below the 300°F (149° C) curve, you have selected a gearbox suitable for your application.
If your torque vs RPM intersection point is above the 300°F (149° C) curve, then you do not have a proper application for that gearbox. Your options are to reduce either your input torque or RPM to get under the 300°F (149° C) curve or try a gearbox with greater capacity.
Output torque = Input torque X efficiency X ratio
Slide-Rite® gearbox Standard Series at 700 RPM and 90 in-lbs (10.17 Nm)
Output torque = (input torque) (efficiency) (ratio)
Output torque = (90 in.-lbs. or 10.17 Nm) (.88) (1:1)
Output torque = 79 in.-lbs. or 8.93 Nm
3:2 ratio journal bearing Float-A-Shaft at 50 RPM and 500 in-lbs (56.49 Nm) (See graph below)
Output torque = (Input torque) (efficiency) (ratio)
Output torque = (500 in.-lbs. or 56.49 Nm) (.62) (3:2)
Output torque = 465 in.-lbs. or 52,54 Nm
