Detailed Description
To make the purpose, technical solution and advantages of the present invention clearer, the following will combine the embodiments of the present invention and the corresponding drawings to clearly and completely describe the technical solution of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the patent without making creative efforts, shall fall within the protection scope of the patent.
The technical solution provided by the embodiments of the present invention is described in detail below with reference to the accompanying drawings.
Referring to fig. 1 and 2, the integrated cable winding and unwinding device of the present invention is disposed inside the casing 11 of the excavator, and a certain gear 8 and a shaft 9 on which the corresponding gear is located on the excavator are selected as the positions where the third wheel 1 is disposed.
It should be noted that, in the selection of the axle 9 on which the large gear 8 and the large gear are located, the axle and the large gear that are already arranged in the excavator structure may be used, or the axle and the large gear that are newly arranged on the existing basis of the excavator may be used. The newly arranged large gear is meshed with the large gear arranged on the excavator, and the rotating speed output is realized.
The idler wheel 1 is arranged on the large gear 8, the copper sleeve 2 is installed between the idler wheel 1 and the large gear 8, and the copper sleeve 2 is provided with an oil groove which serves as a bearing.
An output shaft 4 is arranged at a position parallel to a shaft 9 where the big gear is located, an output gear 3 is arranged on the output shaft 4, the output gear 3 is meshed with the idle gear 1, and the idle gear 1 can rotate to drive the output gear 3 to rotate so as to drive the output shaft 4 to rotate.
In particular, the position of the output shaft 4 may be selected to be capable of meshing with the third wheel 1 and outputting the rotation speed in consideration of the size of the output gear 3, the space of the excavator case 11, and the like.
One end of the output shaft 4 extending out of the excavator box body is connected with the winding drum 5.
Referring to fig. 2, a cylindrical roller bearing 7 is disposed on the output shaft 4 between the output gear 3 and the excavator case 11 in a position close to the output gear 3, and a self-aligning roller bearing 6 is disposed between the cylindrical roller bearing 7 and the excavator case. A transparent cover 10 is fixed between the output shaft 4 and the excavator box body.
The cylindrical roller bearing 7 is of an internal and external separation structure, and when the cylindrical roller bearing is installed, the outer ring is installed in the excavator box body 11, the inner ring is installed on the output shaft 4, and the cylindrical roller bearing is fixed through the check ring. Then, the self-aligning roller bearing 6 is installed on the output shaft 4, the output shaft 4 can be integrally installed from the outer side of the excavator box body 11 because the outer diameter of the self-aligning roller bearing 6 is larger than the outer diameter of the inner ring of the cylindrical roller bearing 7, and then the self-aligning roller bearing is tightly pressed by the transparent cover 10, so that the axial movement of the winding drum is prevented.
An oil seal is arranged on the transparent cover 10 of the output shaft 4 to prevent oil leakage.
At the position that output shaft 4 and reel 5 are connected, the axle head is furnished with axle head baffle 12 for fixed reel 5, and simultaneously, output shaft 4 adopts the spline hookup with reel 5, guarantees that reel 5 can fix on output shaft 4, realizes output shaft 4 and reel 5's synchronous rotation.
The linear speed of cable winding and unwinding is ensured to be consistent with the walking speed of the excavator by calculating the walking linear speed and adjusting the number of teeth of the gear and the diameter of the winding drum 5.
The utility model discloses an excavator integrated cable winding and unwinding devices only increases two gears and a integral key shaft and relevant part in original gear box is inside, need not parts such as independent configuration motor, reduction gear, has practiced thrift manufacturing cost.
