What are the disadvantages of RF67-19.89-M4 helical gear reducer

The disadvantages of RF67-19.89-M4 helical gear reducer are mainly related to its structure and operating conditions. This model belongs to the helical gear reducer series, and its potential shortcomings can be summarized as follows:

1. Difficulty in lubrication during vertical installation
If vertical installation is used, the amount of lubricating oil added needs to be greater than horizontal installation, which can easily lead to internal heating and oil leakage problems due to excessive oil volume. Meanwhile, uneven distribution of lubricating oil may exacerbate the wear of the transmission helical gears.

2. High processing and manufacturing costs
The meshing of helical gears is progressive, and precise control of the helix angle is required during production. The machining process is more complex than that of spur gears, resulting in increased manufacturing and maintenance costs.

3. There is an issue with axial force
Spiral gears generate axial thrust during transmission, requiring additional thrust bearings or thrust structures, which increases the overall structural complexity and assembly requirements.

4. High requirements for assembly accuracy and maintenance
Improper assembly (such as uneven meshing clearance), incorrect selection of lubricating oil, or mixing of different oils can accelerate gear wear and even cause cracks or tooth breakage. Strictly implement the "five fixed" lubrication system in daily life, otherwise abnormal temperature rise (>80 ℃) or copper powder precipitation may occur.
