Description

Technical Field

[0001] The utility model relates to the field of large gear processing equipment, in particular to a half gear connection surface drilling bracket. Background Art

[0002] In recent years, with the gradual growth of the scale of the manufacturing industry and the growth of market demand, the size of equipment such as ball mills has continued to expand, and the required gear size has also increased. For example, the gear diameter of a large ball mill has reached 5 to 10 meters, or even more than 10 meters. Such large gears are usually manufactured in a split form. After split processing, they are combined into 1 / 4 or 1 / 2. After being transported to the installation position, bolts are inserted through the bolt holes on the connecting surface of the half gear to fasten the connection. Since some large gears are helical gear structures, the cross-section of the gear split is parallel to the extension direction of the tooth groove, so the gear split The connecting surface of the half gear body is in an inclined state. When drilling holes on the connecting plate of the half gear body for inserting fastening bolts, it is necessary to lift the end of the half gear body to ensure that the connecting surface of the half gear body is in a vertical state, so as to ensure the fastening effect of the subsequent insertion of bolts on the abutment surfaces of the adjacent gear bodies. However, the current half gear connecting surface drilling type lacks a dedicated inclined lifting bracket and can only rely on the cooperation of multiple hydraulic cylinders to lift one side of the half gear body, resulting in poor supporting stability. In addition, during the adjustment process, there is a risk of overturning of the supporting hydraulic cylinder and falling of the half gear body due to the lifting of one side of the half gear body, which is inconvenient to use.
