Description

Rotating mechanism of sliding frame

[ field of technology ]

[ background Art ]

Existing flying towers generally comprise a tower, and a sliding frame capable of sliding and rotating up and down the tower is arranged on the tower. The skid is capable of rotating on the tower, and is typically connected to the tower by a slewing bearing. The connection mode of the slewing bearing has the following defects: 1. the vibration and noise of the rolling surface of the slewing bearing are different from those of the dust sound, and the vibration and noise can be generated or not, the periodic vibration and noise like a rivet can be generated when the rolling surface of the slewing bearing is cracked, indented or rusted, the period of the vibration and noise can be fixed but is mostly in a certain corresponding relation with the rotating speed, the scratch can continuously occur on a channel, the scratch is hidden on a steel ball at the time, the noise can be changed to a certain extent along with the installation and lubrication conditions, and the vibration and noise can be generated by the slewing bearing/turntable bearing due to the fact that the lubricant is selected incorrectly, the lubricant is insufficient or aged hard, and the noise has no certain rule. 2. The cost is high, and teeth are usually manufactured on one of the collars of the slewing bearing due to the requirement of transmitting force during processing. The heat-treated state of the gear is generally a normalized or quenched and tempered state. The tooth surface can be quenched according to the requirements of users, the quenching hardness is between HRC50 and 60, enough depth can be ensured, the roller path of the slewing bearing is subjected to surface induction quenching treatment, the quenching hardness is between HRC55 and 62, enough quenching layer depth can be achieved, and the processing requirement is high, so that the cost is increased. The slewing bearing rolling body adopts carbon-chromium bearing steel which is hardened integrally; the slewing bearing ring is made of surface hardening steel, and when no special requirement is required by a user, 50Mn steel is generally selected for manufacturing. The slewing bearing rolling bodies are made of carbon-chromium bearing steel which is hardened integrally. Manufactured by GCr15 or GCr15SiMn steel; the slewing bearing ferrule adopts surface hardening steel, and when no special requirement is required by a user, 50Mn steel is generally selected for manufacturing, so that the cost is high.
