Details

1166 oz-in of torque from an HSR-2645CRH! This servo gearbox is to the HSR-2645CRH as the Iron Man suit is to Tony Stark. Combining this factory continuous rotation servo with the servo gearbox creates the smoothest operating continuous rotation gearbox available. Patented

Mechanics: The Top Flange Servo Gearbox framework is machined from 6061-T6 aluminum and anodized to resist scratches and wear. The 3/8" diameter hollow stainless steel output shaft is supported by a pair of ABEC-5 double shielded ball bearings for smooth operation no matter the orientation of the load. The Top Mount Servo Gearbox has tabs on the top edge of the gearbox so that it can be recessed and mounted to a flat surface with minimal deck-height. An excellent choice for panning devices and winch mechanisms.

Electronics: The HSR-2645CRH servo comes from Hitec as a continuous rotation servo; no modifications are necessary which means that the factory Hitec warranty is retained even when installed into the gearbox. Since the servo doesn't require any internal modifications the assembly process is very simple - no soldering required, just bolt it into the gearbox and plug the servo lead into a servo controller! With a continuous rotation servo, the further the signal deviates from center (1500μsec) the faster the servo will rotate. Given there is no positioning feedback and no internal stops in the gear train, the gearbox will continue rotating until the servo receives a 1500μsec signal.

In order to fit your application, all gearboxes are made to order. Use the guide below to make the appropriate selections for your TM-2645CRH-CR Servo Gearbox:

⦁ Ratio: The balance between torque and speed - The 7:1 ratio provides the highest torque and lowest speed while the 2:1 provides the highest speed and lowest torque. Check out the chart under 'Specs' for details.

⦁ Direction Programming: This refers to which direction the Servo Gearbox output shaft will rotate when provided a PWM signal from the servo controller that is over 1500μsec. All servo gearboxes are bi-directional (they're able to rotate either way). The default programming is counter clockwise which means the gearbox output shaft will rotate CCW when the PWM signal received from the servo controller is above 1500μsec and it will rotate CW when the signal received from the servo controller is below 1500μsec.

*This programming can be done with a Hitec servo programmer that's compatible with the servo installed into the gearbox if you have a programmer available or wish to purchase one to tweak your gearbox.

⦁ Assembly: Servo Gearbox assembly can be tedious and requires some general mechanical knowledge. The BM-2645CRH-CM assembly process requires you to install several small Phillips screws but no soldering is necessary. If you are not comfortable assembling your servo gearbox, select 'Assembled' to have one of our technicians assemble it for you!
