The invention relates to a self-lubricating guiding mechanism and device for a grinding motor of a steel rail grinding vehicle, and belongs to the field of mechanical guiding devices. The guiding mechanism comprises a guiding column and a guiding sleeve. The guiding sleeve comprises a self-lubricating bush and a base. A first through hole is formed in the base. The self-lubricating bush is arranged in the first through hole and is coaxial with the first through hole. The self-lubricating bush is matched with the guiding column in a sliding mode. According to the guiding mechanism, the attachment of dust is reduced, and the sensitivity from the guiding mechanism to the dust is reduced. The guiding device comprises the grinding motor and the guiding mechanism. According to the guiding device, fit clearance and relative movement between the guiding column and the guiding sleeve are more smoothly, the grinding precision is higher, and the grinding is more safely.
Description
[0001] technology [0002] The invention relates to the field of mechanical guide devices, in particular to a self-lubricating guide mechanism and equipment for a grinding motor of a rail grinding vehicle. Background technique [0003] Rails are the main components of rail transit. The rails are in direct contact with the wheels of the train, and their quality directly affects the safety and stability of the train, as well as the comfort of the passengers. Due to the dynamic effect of the train, the natural environment and the quality of the rail itself, the rail is often damaged, so it is necessary to eliminate or repair the rail damage in time. Commonly used repair measures include rail oiling, rail grinding, etc. However, due to the high efficiency of rail grinding, it is widely used in rail transit. Among them, a very important equipment is the rail grinding car. [0004] PGM-48, PGM-96, GMC-96 and other models of rail grinding vehicles produced by HARSCO in the United ...
