Brass Spur Gears with Concentric Maxi Torque

custom Machine and Tool co., Inc.’s brass spur gear bored to accept the patented concentric Maxi Torque, a keyless connection bushing system. Spur gears are common gears that transmit motion between two parallel shafts. Used in applications that require speed reduction and torque multiplication such as size reduction equipment, consumer appliances, trains and bicycles.

Brass Spur Gears Features & Benefits:

» Brass gears teeth are hardened due to constant meshing. Gears exposed to harsh environmental weather or chemicals are protected due to the hardening.

» Spur gears are suitable for driving systems due to having more power transmission efficiency.

Gears with the Concentric Maxi Torque:

» Flexible positioning enables customers to easily phase, install, adjust and remove drive components, all while offering precise component positioning.

» concentric Maxi Torque provides uniform surface contact eliminating shaft damage.

» concentric Maxi Torque offers a compact design.

» Improves hub-to-shaft concentricity.

» Speed and ease of assembly.

» reduces inertia.

Engineers at custom Machine & Tool co., Inc. found that fasteners used to connect components to high-speed shafts had to have low inertia and few vibrations. They also knew that component alignment, accuracy, holding ability, and runout became more critical at higher speeds. There was not a compact bushing for shafts less than an inch in diameter that could handle all these tasks. So they decided to design and build one. The result, the concentric Maxi Torque bushing.

How It Works

a single setscrew locks the low-taper angle-split bushing in place without cocking, using a locking-taper design. The same screw is also used to unlock the connection and users reposition the bushing and component. The bushing applies uniform force along its full contact with the shaft. a nd the bushing can be detached, moved and reattached multiple times without damaging the shaft or losing holding torque. The bushing has low inertia, so there’s better shaft-to-component balance. They come in sizes to cover bores from 0.1250 to 1.1875 in. (3 to 30 mm) with torque capacities from 35 to 3, 500 in. lb. (4 to 410 Nm). radial runout is less than 0.001 in. (0.026 mm).

custom Machine & Tool co., Inc. has been a US manufacturer of timing pulleys, drive systems and components for the motion control and power transmission markets since 1964.

New Quick Action Sliding Locks Improve Set Up Time and Reliability

Fixtureworks® (Fraser, MI), a leading North a merican manufacturer and supplier of clamps, fixturing accessories, machine tool components and rollers & bumpers, now offers a complete line of quick action, quick release workholding locks for sliding adjustment, without the need for tools. The adjustable sliding locks are ideal for applications that require frequent disassembly and/or changeover and help improve setup time and reliability in myriad devices.

The sliding locks are available in a variety of configurations from linear rail motion stops, square bar and slotted hole. They also include shaft locking clamps in plastic and zinc as well as pneumatic shaft locking clamps.

The sliding locks are particularly ideal for clamping in tight areas with non-swiveling handles. The body is made from nickel-plated 1045 steel. The handle is made from nickel-plated 4140 alloy steel, quenched and tempered. The push bar is made from 1045 steel.

In the square bar version, the sliding lock is mounted to a plate or table surface. a steel bar travels through the lock and can be locked in place with a quarter turn of the on/off knob. The locking mechanism consists of a wedge that forces a shaft against the surface of the steel bar. The body is made from die cast zinc with a plated chrome finish. The knob is made from reinforced polyamide. The shaft/wedge is made from stainless steel, and the flat spring is made from c 519P phosphor bronze.

The slotted hole design locks in place with a quarter turn of the knob. If the lock is mounted to a plate or table surface, the user can lock a slotted metal bar or plate at varying distances. alternately, the lock can be attached to a plate or another object below a slotted bar to be locked into position anywhere along the slot travel. The locking mechanism consists of a wedge that forces a shaft against the plate surface. The rated load is up to 112 lbs. The body is made from die cast zinc with a plated chrome finish. The knob is also made from polyamide. The shaft/wedge is made from stainless steel, and the plunger is made from polyacetal.

The shaft locking clamps are designed to positively lock a shaft quickly. a s the handle is pushed, a locking block clamps the shaft into position. a s the handle is released, a spring releases the locking block allowing the shaft to move freely. The bodies have mounting holes for use with a position indicator. The body and handle are made from glass-fiber reinforced plastic. The clamp collar is made from SUS630 stainless steel.

Pneumatic Shaft-Locking clamps provide secure clamping of sliding shaft and spindle after position adjustment of parts and units in the machinery. Spring clamping occurs when air is removed, and unclamping when air is provided. Spring clamping and pneumatic unclamping mechanism prevents the decrease of clamping force by air leakage. The body and cover are made from
