The selection principle of the best bearing clearance is proposed to have a certain guiding role

Selecting the best bearing clearance The working clearance of the rolling bearing should be able to guarantee the safety of operation first, followed by obtaining the longest possible service life under this condition, thus establishing that the smaller the working clearance is, the better the working conditions are. Select the principle. There are six main factors that affect the bearing clearance: machining accuracy, bearing inner ring interference, bearing outer ring installation conditions, motor end cap assembly interference, working temperature and bearing load.

Correctly grasp the following three principles, so as to obtain the best free clearance range, and finally select the best working clearance. 1) Safe operation principle Working clearance is the decisive factor for safe and stable operation. The ball bearing is 0.005mm and the roller bearing is 0.01mm. It is the basic guarantee that in the worst operating conditions, it will not cause vicious accidents and cause major economic losses. condition. 2) Grasping the principle of environmental temperature The main factor affecting the working clearance is the working temperature, and the other factors affect the proportion of the operating environment. There is only a small proportion, and only comprehensive consideration is needed. No specific calculation is required. It is worth pointing out that the operating temperature is a statistical average value under certain operating conditions. It is different for different regions of the thermal equilibrium conditions, and usually focuses on the economic principle of the longest integral lifetime in order to obtain higher economic benefits. This means that each operating unit can appropriately reduce the clearance according to the average temperature or maximum temperature of its specific working environment. 3) Simplify the principle of management The free clearance of the bearing of the process document is set. Usually, relevant factors such as measurement accuracy, tooling equipment, and personnel technical level are also considered. In combination with practical experience, the calculation results are simplified and rounded to facilitate management. Practical and practical principles.

The mechanism of fatigue failure of rolling bearing and the fatigue failure process are analyzed in detail. The principle of choosing the best clearance of the bearing is put forward. This has a certain guiding effect on fatigue diagnosis of the bearing and prolonging the life of the bearing.

Gantry Crane

Maximum Load:300.000t

Gantry Crane is a variation of bridge crane. It is well suited for use in storage yard or workshop that does not provide corbels for support. Two forms exist for the product: semi-Goliath and Goliath. With a maximum load handling capacity of 300t,the crane is commonly found at port, storage yard, and outdoor freight yard, where it is used to load or unload bulk goods or various others.

In a gantry crane, the main bridge beam is supported by two supporting legs that run along the rail at the ground level. The main beam can be extended at both ends by using the girder overhangs so that the peripheral area of workshop can be served.

The crane is vital to the material handling process. Crane problems may cause downtime and downtime costs customer`s money. Eurocrane product has always been supplied with consistent good quality, which is sure to become one of your preferred choices in logistics industry. Following is a list of main advantage of our crane product.

Leading Technology and Reliable Performance

We are a pioneer in the manufacture of European gantry cranes. Drawing on the valued experience and advanced techniques, we constantly bring revolutionary innovation to the crane industry. Each product has been rigorously tested prior to being launched onto the market. Hence Customers can purchase with confidence. Our product aims to help customers improve productivity, lower equipment maintenance cost, extend equipment use life, maximize return on the investment, and create more value for the customers.

Compact Structure and Modular Design for Optimized Customer Investment

In its compact body, the crane house many desirable attributes such as even load distribution, light weight, and minimum stress on the rail. It is designed to decrease construction cost and create ease of maintenance. Compared with other domestic cranes, our crane allows for 10% to 15% decrease in its dimension according to the loads that it handles. The heavier the load is ,the more decrease the crane allows in its dimension. In this way, customer comprehensive investment is optimized and rewarded with high rate of return.

Environmentally Sustainable Design for Space-and Energy-Saving

The compact design of our gantry crane leaves more space for industrial operation. All its components are sturdy and long-lasting, requiring limited maintenance. Reduction in weight and wheel stress leads to decreased energy consumption. It also lowers the level of requirements on raw materials during its manufacturing process.

Safe, Reliable, and Easy-to-Maintain
