Pro 4 Tips from HPI Japans R&D Cafe, check the site for more:
in Engrish (sorry)
We would like to introduce Tips which it tries not to break the bevel gear.
1. Please adjust the backlash of the bevel gear appropriately.
Many times it explained this already, but backlash not to be the appropriateness (too multi, when be too little) is not, strength of the bevel gear decreases substantially.
2. Please boil the bevel gear at the hot water.
The material of the bevel gear has used the engineering plastic which designates the nylon resin as the base. Strength of the nylon resin receives big influence to humidity. The present way in the origin of the climate which is dried very there is a tendency which becomes brittle. In order to make the original strength of the bevel gear show, being to have the necessity giving the sufficient moisture to the bevel gear it does.
A) First, the hot water of the sufficient quantity is boiled. As for temperature of the hot water please make sure not to boil. About 80 degrees are good, probably will be. The bevel gear is shifted in your that hot water.
B) That temperature of the hot water does not rise too much, noting, approximately 20 - 30 minutes it does that way. When time passes, lowering the hot water from the fire, until the hot water cools down in normal temperature, it cools that way.
C) When the hot water cools down, very, please take the bevel gear and come out and dry the moisture sufficiently. This time without using the dryer and the like wiping off the moisture with the tissue, and the like it is good to dry that way naturally, probably will be.
D) Sort please assemble after the that usually.
3. Please be sure to paint the grease in the bevel gear. You are not concerned the grease at the extremely small quantity.
Presently, aiming toward further efficiency improvement, it is advancing the test of Pro4.
The high performance (high intensity & high accuracy, also sound is quiet) has tested the thing above now concerning the bevel gear. You think that with the good result would like to report to the cod and everyone.
