Embodiment Construction

[0010] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0011] In the figure, the floating shaft body 1 is in the shape of a slender tube. The two ends of the floating shaft body 1 are provided with shaft ends 2. The shaft ends 2 are short cylinders with a boss in the middle. The outer diameter of the shaft on one side of the boss is the same as The inner diameter of the floating shaft body 1 is the same, and is fixed in the tube body, and the shaft body on the other side of the boss is connected with the wheel shaft through a coupling.

[0012] According to the analysis of transmission mechanics, when the material is the same and the cross-sectional area is equal, the hollow shaft has stronger torsion resistance than the solid shaft, can withstand larger external moments, and is more reliable than the solid shaft when transmitting torque, and can adapt to large The transmission design requirements of the s...

Abstract

The invention provides a trolley walking hollow super-long floating shaft and relates to trolley floating shafts of bridge type cranes. The floating shaft comprises a floating shaft body and shaft ends. The floating shaft body is in the shape of a slender tube. The two ends of the floating shaft body are provided with the shaft ends. The shaft ends are short column bodies. Each shaft end is provided with a boss in the middle. The external diameter of the shaft body of one side of each boss is identical to the internal diameter of the floating shaft body, and the shaft body of the side of each boss is fixed in the tube body. The shaft body at the other side of the boss is connected to a wheel shaft through a shaft coupling. The floating shaft is of a hollow structure, and the two ends are provided with short shaft ends. The hollow structure relieves the shaft deadweight, reduces the deadweight deformation, and suits the transmission design demand of a super-long shaft on a wide span trolley without adding a bearing seat in the middle of the floating shaft for support. The processing technology is simple. It is convenient to install and maintain the floating shaft. The super-long shaft is safe and reliable, and has a low fault rate.

Description

technical field [0001] The invention relates to a floating shaft of a trolley of a bridge crane, in particular to a hollow super-long floating shaft of a traveling trolley. Background technique [0002] Since my country's reform and opening up, the national economy has grown rapidly, and "scientific and technological innovation, independent innovation" has become the mainstream of my country's current industrial development. my country's industry is gradually developing in the direction of intensive, energy-saving, emission-reducing, and low-carbon. With the rapid development of modern science and technology, the expansion of industrial production scale and the improvement of automation, cranes are more and more widely used in the modern production process. In the bridge crane machinery, the trolley is the core part of the crane, mainly composed of a trolley frame, a lifting mechanism, and a trolley running mechanism. In the hoisting transmission mechanism of the trolley, t...
