Composite disc couplings are available in single disc, double disc, floating shaft, and custom models
Ideal for encoders, Control-Flex® Couplings were developed to satisfy today’s higher performance requirements and can be used for parallel, angular and axial shaft misalignments, all while maintaining constant transmission of torque and angular velocity.
To meet this goal, Zero-Max engineered a unique Control-Flex® Disc which is based on a parallel linkage system. Because of this unique design, the reaction forces due to transmission of torque and unavoidable shaft misalignments are considerably smaller when compared with common flexible shaft couplings. They are available with clamp-style hubs or in a bolted-style, drop-out design for easy flexible disc changeout.
Clamp-style couplings provide a positive, secure shaft connection. They have two hubs (that attach to the shafts) and a center flex member that is affixed to the hubs through pins. Our clamp-style couplings are available with a single flex disc for standard torque capacity, or with two flex discs for increased torque capacity, torsional stiffness, and length.
Bolted-style couplings also consist of two hubs (that attach to the shafts) and a center flex member affixed to the hubs through shoulder bolts for drop-out capability. Our bolted-style hubs incorporate a keyway and setscrew shaft attachment.
Zero-Max ServoClass servo motor shaft couplings combine decades of industry leading experience in the manufacture of flexible shaft couplings with unparalleled expertise in motion control solutions. Zero-Max’s high performance servo motor couplings offer numerous features, including:
Zero-Max offers a variety of Schmidt coupling designs, including offset couplings, inline couplings, and 5-D couplings.
These couplings provide the utmost precision for parallel offset shafts. They transmit constant angular velocity and torque in a wide range of parallel shaft misalignments. Schmidt offset couplings impose no radial loads on shafts or bearings, and eliminate radial shaft vibrations. No performance is lost by increasing offset.
Schmidt Inline Couplings are designed with high torsional stiffness. These linkage couplings accommodate small parallel shaft misalignments at constant angular velocity. Designed as dropout couplings, they are easy to install and offer excellent drive performance for low to medium shaft speeds and in medium- to high-torque applications.
These couplings provide parallel shaft misalignment and a ± 5° angular misalignment with moderate axial shaft displacement capabilities. These couplings maintain constant angular velocity at all misalignment modes. Featuring easy to maintain spherical roller bearings, Schmidt 5-D couplings are recommended for high torque, low RPM applications.
4-bolt mounting (non-SAE) accommodates same loads as the Model 200 with ball bearings for motor and pump shafts up to 1 inch in diameter.
SAE “B” 2- or 4-bolt mount using tapered-roller bearings. Standard input bores include: 7/8″, 1″, or 1-1/4″ keyed; 13 tooth 16/32 spline, or 15 tooth 16/32 spline. Also available with 1″ keyed through-bore as a standard.
SAE “C” 2- or 4-bolt mount using tapered-roller bearings. Standard input bores include: 7/8″,1″, or 1-1/4″ keyed; 14 tooth 12/24 spline. Also available with 1″ keyed through-bore as a standard.
SAE “D” mount using large tapered-roller bearings for heavy-duty applications. Standard input bores include: 1-3/4″ keyed, or 13 tooth 8/16 spline.
Both the SAE “E” and SAE “F” mounts have the same physical size; only the pilot diameter and bolt circle are different for motor or pump mounting. These models use large spherical-roller bearings for heavy-duty applications. Input bores are made to customer specifications up to a 2-1/2″ diameter.
Crown Gear’s bevel gearboxes are designed for dependable, economical transfer of speed or power. These premium 90° gear reducers are compact and feature efficient, quiet operating spiral bevel gears. Crown Gear 90 degree speed reducers are available in 1:1 and 2:1 speed ratios with available two or three-way versions. A wide range of miter gearbox shaft styles are also available, as well as specially designed units to handle most applications.
There is a standard process that should be considered before selecting the bevel gearbox that is correct for your specific application. This process goes as follows:
Keyless shaft bushings provide solid connections between the shaft and hub, without stress or wear to mounted components. Using hydraulic pressure to maintain their position, they eliminate keyways, tapers, and tapped holes, which can cause component stress and wear due to fretting, corrosion, and backlash.
A keyless shaft bushing does not rely on the key to transmit torque, but instead utilizes the entire circumference of the shaft for more efficient performance with little to no backlash. Hydraulic pressure is distributed evenly over the full length of the connection, reducing micro-movement which can cause fretting.
Keyless bushings make mounting components an easier, faster, and more precise process. All you need to do is mount, set in position, and lock the bushing with a torque wrench. Unlike bushings with keyways, a keyless locking bushing is infinitely phase-adjustable, both radially and axially. This makes them more precise and easier to use. They can be tightened and repositioned with minimal downtime and without causing additional wear on the shaft or components.
And, because they eliminate the need for milled keyways in shafts, smaller shafts can be used to transmit the same amount of torque, thereby saving space and material.
Zero-Max’s Torq-Tender overload safety devices incorporate torque limiters for dependable overload protection. When a jam-up or excessive loading occurs, the built-in torque limiter will reliably and quickly release to prevent system damage.
The Torq-Tender torque limiter is tamper-proof. Once installed, the torque value cannot be changed. This feature ensures the integrity of the machined design, and renders costly and potentially risky calibration procedures unnecessary. Torque value is controlled by the part number that is ordered; that value determines what spring is used during assembly of the torque limiter.
Zero-Max’s Roh’Lix® linear actuators are threadless, mechanical, screw-type devices designed to convert rotary motion into precise linear motion and thrust using rolling element ball bearings. These adjustable automatic overload protectors will slip when overloaded, providing linear clutching without any additional clutch mechanisms.
The Roh’Lix® is intended for horizontal or vertical axial loading applications. Axial loading allows for even load distribution across all six of the device’s bearings. Sideloads and twisting loads should be avoided whenever possible, as they cause uneven bearing loading and can shorten lifetime. Whenever possible, the load weight on the Roh’Lix® linear actuator should be supported by a separate linear bearing assembly.
The Roh’Lix® is available in five inch and five metric sizes, offering between 15 and 200 lbs. thrust capacity. It can be used in horizontal or vertical applications. All bearings are lubricated for life and require no additional lubrication. Hardened-and-ground shafting with a minimum hardness of 58 HRC is recommended; stainless steel shafting and hollow shafting can also be used for specific applications.
Phas-Lok Adjusting Hubs provide easy and accurate phase adjustment. The Phas-Lok Adjusting Hub is an economical, yet precision device. It provides an easy way to change the phase relationship of a drive component and the shaft. It is ideal for fine tuning timing adjustments, adjusting for chain elongation, and sprocket tooth wear. The Zero-Max Phas-Lok provides an accurate, mechanical adjustment within a 24 degree range. (+/- 12 degrees)
