Bear Varimixer getting warm
The top lid of our 40L Bear Varimixer gets very very hot. I greased the two wheels which has grease nipples with a grease gun (molybdenum disulfide, MoS2). Not sure if this is the correct fat. And I sprayed silicone on the belts and in the slots of the wheels. They called me again today, and told me it is still hot (I can’t compare if the greasing made a difference since I’m not on site). Any insight on this?
I also noticed it won’t run smooth at 5. It squeaks and makes noises if I pass 4.6-4.8 (they never put it to 5, they stop before the point of noise). I’m not sure if this contributes to the heat (that the wheels/springs has to be adjusted / calibrated). It’s been running 3-5 times a week since october 2015 (no service/maintenance).
A few weeks ago, the circuit breaker tripped. They tried to flip it a few times without luck. When I came to the site, it worked again. There was slight corrosion around the poles in the 3-phase plug, but nothing indicating a short/high ohms conduction. I suspect water in the socket, which by the time I arrived had dried up. It was after this visit I noticed the top lid was very hot, and I greased it.
