Abstract

The invention relates to the field of engineering machinery and discloses a track drive wheel, a tracked travelling mechanism and a crane. The track drive wheel comprises a wheel body (1) connected with a driving device and a track meshing portion (3) arranged on the wheel body (1); the track meshing portion (3) has multiple tooth sockets (21) and butting teeth (22) arranged between the tooth sockets (21) in spaced manner, and each of the tooth sockets (21) includes a first side tooth socket (23) and a second side tooth socket (24) which are opposite in an axial opening direction. Therefore, good regulation can be provided for the correspondingly arranged teeth, and tooth gnawing or idling and other undesirable effects in severe working environments can also be avoided.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a crawler driving wheel, a crawler traveling mechanism and a crane. Background technique [0002] Crawler cranes are widely used in petrochemical, nuclear power, wind power, subway, etc. Under construction. [0003] With the increasing demand for crawler cranes in the engineering construction market, the requirements for the design and manufacturing level of crawler cranes are also getting higher and higher. The crawler walking mechanism needs to support the weight of the whole machine, and also needs to complete the movement of the whole machine when it is advancing, retreating, transitioning, and operating, which is the focus of the design of the whole machine. [0004] The crawler traveling mechanism is mainly composed of guide wheels, tensioning devices, track frames, rollers, driving devices, supporting sprockets, track shoes and driving wheels. The meshing and trans...
