The 56mm gearbox and 2 motor adapter were tested independently by BaneBots and FIRST.
The only issue we are currently aware of is with mounting the CIM motor to the 56mm gearbox. We have seen that in some instances the pinion extends too far into the gearbox and causes the gearbox to bind. We have identified three things that may cause this:
1) There is grease between the stages that temporarily holds the stages too far apart. This can usually be resolved by turning the gearbox a few times by hand or removing the internal gears and reinserting them. DO NOT REMOVE THE GREASE FROM THE GEARS.
2) The pinion spacer is to long. If the pinion extends beyond the shaft the spacer is too long. The easiest fix this issue is to shorten the spacer so that the pinion is flush with the end of the shaft.
3) The motor mounting plate is too thin or shaft is too long. We have recently seen small variances in the thickness of the mounting plate and the length of the CIM motor shaft. If the pinion is flush with the end of the motor shaft and there is still a problem, this is likely the problem. There are two ways to address this problem. You can either shorten the CIM shaft and spacer or you can add a thin spacer between the gearbox and the motor mounting plate.
With proper correction, the mounting problem does not affect the reliability of the gearbox. We do not know of any reliability issues with either the gearbox or the two motor adapter.
Please keep the following two points in mind:
- Either support the gearbox shaft or keep the load as close to the face of the gearbox as possible.
- Do not depend on the gearboxes to support the weight of the motors - support the CIM motors.
