Helical gear reducer with parallel shafts
Gear reducer Also known as a gearbox, gear drive, or reducer, it is an enclosed mechanical device that uses gears to reduce the speed of an electric motor while increasing its torque. Various types of gear reducers are available to suit specific applications.
Helical gear reducers with offset shafts offer a range of unique advantages. In helical gears, the tooth flanks are inclined. Compared with other types of gears, helical gears are highly efficient and remarkably quiet, thanks to their higher contact ratio. The term “offset” refers to the fact that the input and output shafts do not lie on the same straight line.

Many different industries use helical gear reducers with offset shafts. Specific applications include conveyor systems, packaging equipment, cranes, winches, hoists, agitators, and mixers.
DAC Worldwide’s dissectible in-line helical gear reducer (205-150) is one of a broad range of practical industrial gear reducer dissections, suitable for hands-on mechanical transmission training in the classroom or laboratory.
Each anatomical dissection unit is constructed from a genuine industrial machine that has been cleaned, refurbished, and repainted, and is mounted on a modular, large‑size, formed‑steel base. It can also be installed on compatible DAC Worldwide workbenches, workstations, or storage solutions.
Retain all major functional features and provide replacement hardware when necessary. The disassembly, inspection, and assembly exercises offer learners hands-on experience with a common industrial helical‑spur gear reducer.

Industry-standard components provide realistic hands-on training.
Technical training is most effective when learners can directly engage with industry-standard components they encounter on the job. The disassemblable unit is a meticulously restored, segmented industrial helical‑gearbox, providing learners with a realistic training experience and fostering skills that are readily transferable to the workplace.
The detachable offset in-line helical gear reducer is a robust unit mounted on a No. 7 formed steel baseplate, suitable for desktop, workstation, or rack‑mount applications. When required, it is coated with a highly durable polyurethane finish. Each disassemblable component is accompanied by the original manufacturer’s applicable installation and maintenance manual.
Expand training capabilities through custom options.
The offset in-line helical gear reducer can be customized with available options to create a training system tailored to specific industries or user requirements. For example, these customizable options include: IPT industrial trade training manuals or handbooks, relevant textbooks, gear‑drive maintenance toolkits, and electromechanical workstations.
