Details:
HCQ138 marine gearbox has the functions of inverting, forwarding, clutching, decelerating, and bearing the thrust of the propeller. The gearbox is a vertical heterocentric one-stage transmission structure, which has the characteristics of small size and lightweight.
Causes and treatment of common failures of gearboxes:
1. Abnormal sound of gearbox
There are bumps on the gear tooth surface causing noise
Situation: This problem is mainly reflected in the testbed of the assembly plant of the complete machine manufacturer. The characteristics of this abnormal sound: the frequency of the sound is stable, there is abnormal sound in one direction, and there is no abnormal sound in reverse rotation. The speed and abnormal sound of the low-speed shaft can be calculated The frequency relationship of the noise to determine the specific location of the abnormal noise.
Reason: bumps occurred during the assembly process. Due to the company's flaws in the quality control of the test, a very small number of gearboxes may have such problems.
Treatment: According to the analysis results, carefully look for the bumps on the tooth surface of the relevant gear. When searching, wipe off the oil on the tooth surface to avoid affecting the feel. Bruises mainly exist on the tooth top and both sides of the tooth profile.
2. The gearbox oil temperature is too high
The two outlets of the filter are respectively marked to the gearbox or to the cooler. When the temperature is low, it directly enters the oil distributor, and when the temperature is high, it enters the cooler. If the oil pipes are connected reversely, the high-temperature oil will not be cooled by the cooler, which will inevitably cause excessive oil temperature. It can be solved by installing the tubing according to the correct requirements.
3. The high-speed shaft bearing temperature is too high
The operation of the bearing must ensure a certain radial clearance. When the clearance is too small, the rollers and raceways will become suffocated, and a lot of heat will cause the temperature to rise. This situation is relatively rare, you can use a feeler gauge to detect the radial clearance of the upper end of the bearing.
