actuator 1000lbs. Load

The Motion 85199/85200 Ball Drive Actuator incorporates all of the features of the 85151/85152 unit except the larger Motion Ball Drive 85039 is used to transmit thrust rather than the 85010. The 85039 with a diameter of .979 permits a load rating up to 1000 lbs. which can be extended in certain applications. It also has integral freewheeling at stroke ends to eliminate limit switches. The 85199 uses a translating tube for mounting, while the 85200 is an open screw type unit where attachment is made directly to the ball nut.

The 85039 Ball Drive has an advancement per revolution of .281 which generally results in higher stroke speeds for the 85199/85200. There are certain motor and gear ratio combinations that will not produced 1000 lbs. of thrust and these are detailed in the technical data. This device has a unique freewheeling feature to prevent over travel at the end of stroke. A ball cage within the nut ID cams up against stop pins at each end of travel to initiate freewheeling and linear advancement stops. The stop pins are mounted in the screw thread and are factory installed for the specified stroke. This design generally eliminates the need for externally mounted limit switches. All elements: screw, nut and ball cage are heat treated alloy steel with bearing surfaces for long wear characteristics. The nut is provided with a 1 9/16 thread for attachment of the translating tube on the 85199 or for direct mounting on the 85200 .

Gear Reducer Motor speed reduction to drive the 85039 Ball Drive is by a single stage worm gear reducer. The housing is die cast aluminum alloy. A molded neoprene coupling with steel inserts couples the motor shaft to the worm shaft and provides protection against shock loads. The worm shaft runs in an oilite bearing at the motor end and a ball bearing at the opposite end. The Ball Drive is mounted in a ball bearing at the output side of the gear reducer which takes axial thrust loads, and an oilite bearing at the opposite end. Both the worm and gear are heat treated steel for long wear life. The ratios are: 10:1, 20:1 and 40:1. The gear reducer is sealed and permanently lubricated with a high grade synthetic grease. Special lubricants are available for extreme applications such as low temperature.

Motors:

115 VAC, 220 VAC, 12 VDC, 24 VDC and 115 VDC motors are all stock units. The AC motors are permanent split capacitor induction type and are specifically designed for high starting torque with an intermittent duty cycle (25%). Either a 1500 or 3200 RPM speed may be selected and a 1500 RPM continuous duty version is also available. DC motors are permanent magnet brush type. An intermittent duty cycle (60%) is required on DC units. No load speeds are 6000 RPM and 3000 RPM. Motors with other voltages and performance characteristics are available on request.


Gearbox Mounting:

Normally the Type B gearbox mount with a .500" diameter cross hole oriented parallel to the motor shaft is provided; however a type C 90˚ orientation or any other angle can be specified to facilitate mounting and clearances in customer equipment. Other diameter cross holes can be provided such as .625"


Brakes:

A bi-directional friction brake which provides load holding and antidrift is normally specified with the 20:1 and 10:1 gear ratios. The 20:1 takes a standard friction brake, while the 10:1 uses a heavy duty version. Many linkage type applications have balanced loads where a brake is not necessary. While the 40:1 ratio is self –locking, either the standard or heavy duty brake can be added to give quick stopping for positioning type applications.
