Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1 to 7, a large bevel gear comprises a spindle 1 and gear teeth 2, wherein an installation key slot 3 is formed in the spindle 1, an assembly auxiliary piece 5 which can move in and out along the installation key slot 3 is arranged at the center position of the top end of the spindle 1, the assembly auxiliary piece 5 comprises a support shaft 53, an inner disk surface 51 and an outer disk surface 54 which are arranged on two sides of the support shaft 53, and a rubber pad disc 52 is further arranged on the inner side of the inner disk surface 51;

the support shaft 53 is provided with a first hanging groove 55, the bottom surface of the outer disk surface 54 is provided with a second hanging groove 56, and the mandrel 1 is provided with a third hanging groove 6.

To current large-scale bevel gear when the assembly, be difficult for hoist and mount the worn and torn problem of easy hoist and mount, install assembly auxiliary 5 on the bevel gear of this scheme, assembly auxiliary 5 is fixed accomodate under the user state, and when the assembly is used, can shift out to supplementary bevel gear's hoist and mount is installed, and is specific: 1. during normal assembly, the assembly auxiliary piece 5 is moved out, and a padlock (hanging chain) is sleeved on the second hanging groove 56, so that hanging is completed; 2. when the device is inverted, the assembly auxiliary piece 5 is not moved out, and a padlock (hanging chain) is sleeved on the third hanging groove 6, so that hanging is completed; 3. during frequent side mounting, the assembly auxiliary piece 5 is moved out, and two groups of padlocks (hanging chains) are respectively sleeved on the first hanging groove 55 and the third hanging groove 6 to finish hanging;
