How to handle an oversized gearbox bearing bore?
During the repair process, we discovered that the bearing bore on the gearbox side near the drying drum is worn—unevenly, with some areas showing deeper wear, reaching up to about 10 mm in certain spots, though the average wear depth is around 3 mm. The bearings and shafts are matched using return sleeves. The bearing model is 22313, operating at a speed of 745 rpm, with temperatures not exceeding 90°C. Do you know how to address the issue of oversized bearing bores in the gearbox?

Improvements to prevent gearbox oil leakage
A company provides on-site equipment lubrication services, and during inspections, several areas within the plant were identified as problematic. Specifically, some of the equipment is used to lift steel ladles weighing 80 to 120 tons, featuring relatively large bearings under extremely harsh operating conditions. As a result, gearboxes in these systems exhibit varying degrees of oil leakage—a common headache for most steel plants. Below, we’ll analyze the root causes of the gearbox oil leaks and outline steps for improvement.

As enterprise production equipment evolves toward larger-scale and more integrated systems, the operation of these machines requires more efficient power transmission—and this is precisely where gearboxes come in. In industrial production, gearboxes serve critical functions: they enable devices to speed up or slow down; change the direction of power transmission; distribute mechanical power among different components; and perform other essential tasks. Once a gearbox develops a leak, not only does it impair equipment efficiency, but it can also increase the risk of safety hazards like fires.

How can the gearbox leakage issue in paper-making enterprises be resolved?
As times have evolved, paper has become an indispensable part of people's daily lives, and the paper-making industry has consequently flourished. Gearboxes play a crucial role in the paper production process—they drive the entire production line. Once a gearbox starts leaking oil, it not only disrupts production efficiency but also contaminates the paper, ultimately compromising its quality.

White corrosion cracks in industrial gearboxes
Industrial gearboxes are widely used in the field of industrial equipment, including some extremely harsh working conditions. The continuous advancement of industrial gearbox technology has greatly improved industrial production efficiency and reduced operating costs. However, the impact of gearbox failures remains significant—for example, complete shutdowns, production losses, revenue losses, and even contract losses.

Let's take a look at the performance of gearbox faults
A transmission is an industrial component that transmits power through a set of transmission wheels. At the same time, gearboxes, as mechanical parts of transmission gears, are widely used in the chemical industry. The following discusses in detail the common fault manifestations and diagnostic measures of gearboxes, starting from their applications.

Gearbox Fault Diagnosis Methods
A gearbox is a unified mechanical assembly that houses both gears and bearings. Any gearbox failure—whether caused by manufacturing defects or operational stress—deserves careful attention. Generally, the following methods are commonly used to diagnose gearbox issues.

Reasons for Unusual Noises in Gearboxes and How to Address Them
During the gearbox assembly process, there were instances of minor磕碰. Due to the company's shortcomings in quality control testing, such issues are rare in most gearboxes. Solution: Based on the analysis results, carefully inspect the tooth surfaces of the relevant gears for any scratches or scuffs, and thoroughly remove any oil or grease from the tooth surfaces to ensure a smooth feel during handling. The protrusions are primarily located at the tooth tips and along both sides of the tooth profiles.

What is a gearbox, and what does it do?
A gearbox is a mechanical device that increases or decreases torque by reducing or increasing speed. It consists of two or more gears, one of which is driven by a motor. The output speed of the gearbox is inversely proportional to the gear ratio. Gearboxes are typically preferred for constant-speed applications, such as conveyors and cranes, where they can deliver significantly higher torque.

The Importance of Gearbox Cleanliness
Since wind turbine rotor speeds are typically low—far below the speeds required for generators to produce electricity—they must be increased using the gear ratio provided by the gearbox’s gear pairs. That’s why the gears in a gearbox are also referred to as "speed-increasing gears." Now, let’s explore together the importance of gearbox cleanliness!
