Embodiment Construction

[0019] A preferred embodiment will be given below, and the present invention will be described more clearly and completely in conjunction with the accompanying drawings.

[0020] The main components of the crane walking wheel open gear lubrication system of the present invention are: fuel tank 1, oil circuit switch, oil pipe 3, solenoid valve 4, flow regulating valve 5 (flow switch), dripping oil pipe 6 and joints, as figure 1 shown.

[0021] Considering that the lubricating part is an open gear, the system uses No. 220 gear lubricating oil with a relatively high viscosity. This type of gear oil has strong adhesion, which can prevent the gear oil from directly flowing out of the tooth surface. When the gears mesh with each other, the gear oil is squeezed to the tooth root, and when the gears are not meshing, the gear oil slowly spreads out. The meshing surfaces are always lubricated by lubricating oil, so as to realize the long-term lubrication of the gears.

Abstract

The invention provides lubricating systems for walking wheel opening gears of a crane and a crane comprising the lubricating systems. Each lubricating system comprises an oil tank, an oil pipe, a solenoid valve, a flow adjusting valve and an oil dripping pipe; one end of the oil pipe is connected with the oil tank; the other end of the oil pipe is connected with the solenoid valve; the solenoid valve is used for controlling the opening and closing of the lubrication system; a plurality of lubricating systems are arranged on a trolley balanced beam of the crane; each lubricating system corresponds to one group of walking wheel opening gears; a through hole is formed in the housing of the walking wheel opening gears and is aligned with the oil dripping pipe. Thicker gear oil is used for replacing grease, the oil dripping lubricating function is realized by using the solenoid valve to control the opening and closing of an oil path, automatic oiling and lubrication and precise oiling quantity are realized by using the controllability of the solenoid valve, time and labor are saved, the walking wheel opening gears are efficiently lubricated, and the whole system is simple, easy, light, convenient to disassemble and overhaul and low in cost.

Description

technical field [0001] The invention relates to the field of hoisting equipment, in particular to a lubricating system for an open wheel gear of a crane and a crane including the same. Background technique [0002] The driving mode of the crane is usually that the motor drives the open gear on the running wheel through the reduction system to drive the running wheel to run. Since the deceleration system is open except the deceleration box, the traditional lubrication method is grease lubrication, which has many defects in the implementation process: 1) Do not apply too much grease, because the grease is squeezed out when the gears mesh, Falling to the ground pollutes the environment and wastes grease; 2) The grease cannot be maintained all the time, and the formed oil film will disappear after multiple meshes, and the grease that is squeezed to the side cannot flow back to the meshing surface, and grease needs to be applied frequently; 3) 1. Grease and lubrication are time-...
