At present, the transmission form of 4-axis robots on the market mainly has two structures: belt and gear, of which the belt organization is the majority, but the gear structure also appears in some well-known.
Each of the two structures has its own characteristics, which are briefly summarized below:
First of all, the belt structure:
1. Easy to replace, low cost;
2. Because the belt is tough, even if there is a serious impact, it will not damage important parts;
3. There will be tooth skipping, resulting in the loss of the origin;
4. There are requirements for the tension of the belt;
Secondly gear structure:
1. It is not suitable to produce skipping teeth;
2. Long life, but relatively difficult to replace;
3. In the event of a serious impact, important parts may be damaged;
For example, if a customer expects the robot to be used more durably, then it is recommended to use the belt structure, which can be replaced by a simple belt, that is, after a long time of use, it can also be restored to the factory accuracy; If the equipment is not old for a long time and is not willing to spend a high cost on maintenance, then the gear structure can be a good choice.
