and Maintenance Manual

•Read and follow all instructions carefully.

•Disconnect and lock-out power before installation and maintenance. Working on or near energized equipment can result in severe injury or death.

•Do not operate equipment without guards in place. Exposed equipment can result in severe injury or death.

•Never lift the reducer by the input shaft. Lifting lug should only be used to lift the weight of the reducer. Do not use lifting lug to lift attached assemblies.

•Reducer shipped without oil. Fill to proper level before operation to avoid damage and/or personal injury. Do not use lubricants with anti-wear/extreme pressure additives in units with internal backstops - these additives decrease the backstops’s ability to prevent reverse rotation and will result in backstop failure which could cause personal injury.

•Periodic inspections should be performed. Failure to perform proper maintenance can result in premature product failure and personal injury.

•All electrical work should be performed by qualified personnel and compliant with local and national electrical codes.

1. Shaft Mount Reducer Installation Instructions

For long service and dependable performance, a shaft mount reducer must be rigidly supported and accurately aligned. The following instructions are a step-by-step guide to meeting these requirements for a Browning® TorqTaper Plus shaft mounted reducer. If there is a need to vary from any of these installation instructions, contact the Regal Power Transmission Solutions Application Engineering Department at 1-800-626-2093 before completing the installation.

CAUTION: Shaft mounted reducers use bushings to mount the reducer to various driven shaft sizes. When the driven shaft is smaller than the maximum bushing size for the reducer, check the driven shaft and key stresses per ANSI/ AGMA Std. 6001-D97 for the application.

1.1  Reducer and Driven Shaft Preparation

1.1.1  The driven shaft diameter is to be within the commercial tolerances for turned and polished round bars. The key and keyseat in the driven shaft are to be in accordance with commercial standards for size, depth, offset, lead and parallelism.

1.1.2  The driven shaft on which the reducer is to be mounted must be straight, clean and free of burrs.

1.1.3  Rotate the driven shaft on which the reducer is to be mounted so the shaft keyseat is in the upward position.

1.1.4  A lifting lug is provided to lift the reducer into position. The lifting lug may be repositioned onto any one of the housing flange bolts as required. After repositioning, all housing flange bolts must be reinstalled to the recommended torque. See bolt torque specifications section.

CAUTION: Do not apply grease, oil or an anti-seize compound to the taper bore of the reducer, barrel of the bushing, driven shaft or bushing bore. If any of these substances are applied, equipment failure and personal injury may result.

1.2.4  Using the appropriate reducer size in the Tables 1-3, 1-4 and 1-5, compare the measured values for H and K to the tabulated values of H and K. If the measured values for H and K are greater than the tabulated values, the mounting configuration shown in the figure may be used. If the measured values for H and K are less than the tabulated values, proceed to the next figure and repeat this step.

Notice: If the measured values for H and K are less than the tabulated values shown in Table 1-5, contact the Regal Power Transmission Solutions Application Engineering Department at 1-800-626-2093.

1.2  Determine Mounting Configuration - Bushed Bore Models

Due to its unique design, the Browning TorqTaper Plus shaft mounted reducer may be mounted to a driven shaft in a variety of configurations. The following instructions will help determine the correct mounting configuration based on the available driven shaft and key length.

1.2.1  Measure the available driven shaft length “H” (in inches) starting from the end of the driven shaft to the first obstruction or point of interference.

1.2.2  Measure the length of the available keyseat “K” in the driven shaft (in inches) starting from the end of the driven shaft to the end of the usable keyseat.

1.2.3  The following Sections - 1.3, 1.4 and 1.5, show the three standard mounting configurations for the Browning TorqTaper Plus shaft mounted reducer. Refer to the following sections in sequence to determine the optimum mounting configuration for the application.

Table 1–2 Shaft Diameter Tolerances for Inch Shafts

Shaft diameter, in	Maximum undersize variation, in¹
To 1.50	0.004
Over 1.50 to 2.50	0.005
Over 2.50 to 4.00	0.006
Over 4.00 to 6.00	0.007
Over 6.00 to 8.00	0.008

Note:

¹) Keys and keyways in supporting shaft should be in accordance with

ANSI B17.1 for size, depth, offset, lead and parallelism.

1.3.1  On the input shaft side of the quill, thread the bushing ring onto the hollow quill one or two turns past the end of the quill.

1.3.2  Place the endcap on the driven shaft with the threaded bore facing the end of the shaft. Slide the stabilizer ring on the driven shaft with the small end of the taper toward the end of the shaft.

1.3.3  Install Key(s)

Type 1 Bushing (2 Keys):

•Install the external bushing key into the bushing as shown in Fig 1-1 (External bushing key is supplied with the Bushing Kit)

•Install driven shaft key (customer supplied) into the driven shaft keyseat. Position the end of the driven shaft key even with the end of driven shaft. Retain this key to prevent movement.

1.3.4  Install Reducer

Type 1 Bushing

•Mount the reducer on the driven shaft with the bushing ring facing outward toward the end of the driven shaft.

•Locate the reducer on the driven shaft such that approximately .500 inch of the driven shaft extends out beyond the end of the reducer quill.

•Start the bushing (small end first) by aligning the keyway in the bushing with the key previously installed in the driven shaft.

•Continue moving the bushing into position and rotate the input shaft as required to align the external bushing key with the keyway in the reducer quill.

•Rotate the bushing ring clockwise to align the clearance holes in the bushing with the threaded holes in the bushing ring. (This will require less than ½ turn of the bushing ring).

•Install the bushing capscrews and hand tighten. Reposition the reducer until the end of the driven shaft is even with the end of quill.

•Slide the stabilizer ring into the reducer quill and thread the endcap on hand tight

•See bolt torque specifications section.

•Tighten the bushing capscrews evenly around the bushing flange to the recommended torque as shown in Table 6-1.

•Tighten the endcap again until hand tight. Tighten the set screw in the endcap to the recommended torque as shown in Table 6-1.
