Input Shaft Tradeoff Options for Single Speed Gear Reducers

EV work continues despite reduction in volume

Greetings 2026! As expected, EV demand has waned following some deregulation and tax credits being dropped as of September 2025. For us industry folks, this is simply reality catching up with the narrative. On the plus side, 2025 was a very good year for global vehicle sales–the best since 2019 (Ref. 1). A good economy can forgive many blunders. As gearbox designers, our work continues as our EV offerings are likely a permanent part of our product lineup, even if at a reduced volume. When it comes to single speed offset gearboxes, many OE’s have a similar 3 parallel shaft design, running ratios typically between 7:1 to 15:1. Some higher speed boxes are going above 20:1 ratio now, but the basic architecture is unchanged. The Tesla design shown here is a common baseline design:

Safe, Reliable Spindle Operation

The load limit diagram of a motor spindle serves to graphically represent the permissible operating range as a function of parameters such as rotational speed. It enables a quick assessment of the conditions under which the spindle can be operated safely and reliably without exceeding mechanical, thermal or dynamic limits. Such a diagram is a key tool for the design, selection and evaluation of spindle systems in mechanical engineering particularly in the field of machining where high demands are placed on precision, performance and service life.

A Focus on Craftsmanship

Consider the following scenario: guided by vision sensors, a robot spots a product on a moving conveyor, determines its exact position and, in one fluid motion, picks it up and places it into a waiting assembly, carrier tray, or shipping container. What human operators once found tiring—or at least tedious, the robot performs flawlessly, hour after hour, even long after its flesh-and-blood coworkers have gone home for the evening.

Advanced Lubrication Technology

Operating for long hours, under extreme loads, in high temperatures and dusty environments, ongoing wear is a significant challenge for open gears. This can lead to unplanned downtime and reduced equipment life—creating a barrier to effective operations. Leading mining and cement companies use advanced grease technology and technical inspections to help prevent open gear failure, optimize service life and ensure the smooth running of their operations.

Greener Days

Despite a lukewarm sustainability agenda here in the United States, global bearing manufacturers continue to be motivated by eco-friendly technologies, environmental awareness and energy efficiency regulations. Material innovation is one of the key strategies to reduce environmental impact moving forward. Concerns include energy consumption in manufacturing, waste generation, emissions from lubricants and raw material extraction. The end goal is to provide longer-lasting components with less waste.

Gears

This study presents a simulation method for considering complex wheel bodies in an analytical tooth contact model. The wheel body is considered using reduced FE stiffness. Reduction points are defined over the width and linked with the analytical gear.

For cylindrical wheel bodies, comparative calculations show fewer deviations from the expected results with the new method. This is due to the additional degrees of freedom in the FEM model. In the calculation with cylindrical wheel bodies, bending due to axial force in tooth contact could also be verified in addition to the deformation in tooth contact and the influence of the shaft-bearing system.

Bearings

Since taking over as CEO of Solve Industrial Motion Group in June 2024, Ernie Lauber has focused on continuous improvement, predictive maintenance and growing the legacy brands within Solve.

Combining brands such as IPTCI, MasterDrive, PTI and TRITAN together with the LMS, SST, SPB-USA and USA Roller product lines, Solve Industrial Motion Group is a provider of high-quality metric and American Standard power transmission components and industrial-grade bearings.

Motors

Unlike HVAC applications, servomotors are not normally operated at the same speed or torque for extended periods, thus the overall efficiency of a servomotor is not easily given a single numeric value. The efficiency varies greatly with the application, and thus different applications favor different types of servomotors.
