Gears & Gear Racks
Gears and gear racks are elements in mechanical systems and play a significant role in transmitting power and motion. Gears are typically circular components with teeth along their circumference, and they mesh with other gears to facilitate controlled rotational movement. Gear racks are straight or flat pieces with similar teeth , usually used with a circular gear.

About Gears & Gear Racks
Gears and gear racks are fundamental components in mechanical engineering. With their distinct toothed design, these devices are pivotal in transmitting torque, adjusting rotational speed, and changing the direction of power transmission. By engaging with each other, they can convert linear motion into rotational motion or the other way around, contributing significantly to various applications ranging from analog clocks to automobiles.
Gears are integral components in many mechanical devices, transmitting power, adjusting speed, or changing the direction of force. Several types of gears serve specific applications:
Spur Gears: These are the most common type of gear, characterized by straight teeth mounted parallel to the gear's axis. Spur gears transmit power between parallel shafts.
Helical Gears: Similar to spur gears, their teeth are machined at an angle, allowing for more gradual and smoother gear engagement. Helical gears work well in high-speed applications because they are efficient and quiet.
Bevel Gears: With teeth along the cone surface, these gears change the direction of the shaft's rotation.
Planetary Gears: Consisting of a central 'sun' gear surrounded by 'planet' gears, this setup is used in automobile transmissions to provide different speed and torque outputs.
Worm Gears: These have a unique design where a 'worm' (screw) meshes with a gear/wheel. Worm gears help make significant gear reductions and have the advantage of self-locking.
Each gear type serves a unique purpose in mechanical engineering, contributing to the functionality and efficiency of various devices and machinery.
Gear racks are integral components in many mechanical and automation applications. They are straight bars or rods with teeth cut into them, designed to mesh with gears for converting rotational motion into linear motion. This mechanism works in various industries, such as automotive, manufacturing, and robotics. In the automotive industry, for instance, gear racks are commonly found in steering systems. These help translate the steering wheel's rotational movement into the linear motion for steering the wheels. In robotics, gear racks achieve precise linear motion for tasks such as assembly or positioning.

Bevel Gears
Bevel gears are used as right angle drives where high efficiency is required. Most all of Martin bevel gears are cut with the "coniflex" tooth form to allow for a slight misalignment at assembly and during operation. Gears should be mounted at the correct distance from the core of apex center with thrust bearings being used in back of hubs to absorb the backward thrust created in this type of gearing

Machined Gear Rack
Martin rack is made from low carbon cold drawn steel and cold drawn steel. It is available in 14½° and 20° pressure angle in 2, 4, and 6 foot lengths. Allowance is made for cutting and machining. Pinions to run with the rack may be selected from the spur gear section of the catalog. Special rack can be supplied in other materials, sizes, and pitches
