ATK-25 Alignment Tool Kit

Product Description

The ATK-25 is a unique shaft alignment solution, specially designed for small equipment. The ATK can be used to measure parallel and angular alignment, for correction of pitch, yaw, vertical, and horizontal positioning. It works in crowded or constrained locations where other tools will not fit.

Alignment is critical for rotating equipment. Poor alignment can cause:

  • Excessive Vibration: Misaligned shafts lead to higher vibrations, which can result in mechanical failure or decreased performance
  • Increased Wear and Tear: Bearings, seals, and couplings can experience premature wear due to the
    additional forces exerted by misaligned shafts
  • Equipment Failure: Continuous operation with misaligned shafts can lead to mechanical failure,
    resulting in costly repairs and downtime
  • Reduced Quality: In many industries, precision machinery is critical to maintaining product quality

Proper alignment tools and techniques provide major benefits, and are essential to achieving:

  • Smooth operation, with the lowest noise and highest performance
  • Long lifespan of component parts and minimum maintenance costs
  • Reliable Operation, with the minimum downtime
  • High production quality

Motor testing also requires good shaft alignment to produce the most accurate and consistent results. Unfortunately, the shaft alignment solutions widely available are not designed for use with smaller equipment.

Held on the V-block of one shaft, the ATK measures two tangent points on the target shaft. From those two measurements, angle can be determined from rise-over-run. Parallel position can be determined by measuring the target shaft on two sides, 180° opposite.

The ATK-25 includes attachments to accommodate a range of axial spacings between shaft ends. It includes a high-quality depth indicator, and is supplied in a durable, fitted case with all necessary tools.

Features

  • Unique shaft alignment solution, specially designed for small equipment
  • Works in crowded or constrained locations where other tools will not fit
  • Measures parallel and angular alignment, for correction of pitch, yaw, vertical, and horizontal
    positioning
  • For shaft sizes: Ø5 … Ø25 mm (also suitable for Ø3/16 in … Ø1 in)
  • User friendly design

                    [post_content] => Eddy-Current Brake Dynamometers (WB Series) are ideal for applications requiring high speeds and also when operating in the middle to high power range. Eddy-Current Brakes provide increasing torque as the speed increases, reaching peak torque at rated speed. The dynamometers have low inertia as a result of small rotor diameter. Brake cooling is provided by a water circulation system, which passes inside the stator to dissipate heat generated by the braking power, providing high continuous power ratings (max. 140 kW). WB Series Dynamometers integrate a torque measuring system with accuracy ratings of ± 0.3 % to ± 0.5 % full scale, depending on size and system configuration.

Features

  • 12 Models with Maximum Torque from 400 mN·m to 560 N·m (56.6 oz·in to 413 lb·ft)
  • Braking Power: from 500 W to 140 kW
  • Stable Braking Torque, without Shock
  • Low Moment of Inertia
  • Low Residual Torque
  • Operating Direction CW / CCW
  • Braking Torque Measurement Integrated
  • High Rotational Speed (≤ 80 000)
  • Integrated Optical Speed Sensor
  • Special designs available upon request

Operating Principles

The WB Eddy-Current Dynamometers develop their full power at high rotation speeds. The WB Series is particularly intended for motors which rotate at high speeds, up to 80 000 rpm (up to 100 000 rpm with WB 23 / 27; see specific datasheet). The braking torque depends on the rotation speed. Optical Speed Sensor Each WB Series Dynamometer is equipped with an optical speed sensor. WB 32 is equipped with a 4 PPR (Pulses Per Revolution) encoder, WB 43 and WB 65 HS are equipped with a 30 PPR encoder; WB 65, WB 115 & WB 15 are equipped with a 60 PPR encoder.

These versatile fixtures align the motor under test with Magtrol’s HD-100, HD-106, HD-400, HD-500, HD-700 and HD-800 Series Dynamometers for easy setup and coupling—couplings can be provided upon request. Various adaptor rings (sold separately) can be customized to allow several different motors to be tested on the same fixture. FMF Fixed Motor Fixtures can be mounted to any Magtrol Dynamometer T-slotted long base plate or any Hysteresis Dynamometer Table with grooved table top (TAB 1457S, TAB 0800L and TAB 0825L). These fixtures are equipped with a precisely located rectangular key on the bottom of the plate for easy centering. Also included are four adjustable clamping levers and T-nuts.
