DETAILED DESCRIPTION
[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] See also Figure 1-Figure 4 In this embodiment: a rotary kiln driving device includes a gear ring 1 and a power structure 2, please refer to Figure 2 The gear ring 1 includes a first positioning ring 11, two second positioning rings 12 and a plurality of gear teeth 13. The first positioning ring 11 is welded to the outer side of the cylinder 3 of the rotary kiln. A plurality of slots 11-1 are arranged on the outer side of the first positioning ring 11. The plurality of slots 11-1 are distributed in a ring array with the central axis of the first positioning ring 11. The number of slots 11-1 is the number of teeth of the gear ring 1. The specific number of slots 11-1 depends on the actual situation. The two second positioning rings 12 are respectively welded to the two ends of the first positioning ring 11. Each second positioning ring 12 is provided with first mounting holes 12-1 equal to the number of slots 11-1. The first mounting holes 12-1 on the two second positioning rings 12 are opposite to each other and are respectively located at the two ends of the slots 11-1. A gear tooth 13 is inserted in each slot 11-1, and the gear tooth 13 is fixed between the two second positioning rings 12 by bolts 14 and nuts 15.
[0020] See also Figure 1 The power structure 2 includes a base 21, which is fixed on the ground. A motor 22, a reducer 23 and a bearing seat 24 are installed on the base 21. A rotating shaft 25 is rotatably installed on the bearing seat 24, and a gear 26 is fixedly installed on the rotating shaft 25. The gear 26 is meshed with the gear ring 1. The output shaft of the motor 22 is connected to the input end of the reducer 23, and the rotating shaft 25 is connected to the output end of the reducer 23. The reducer 23 reduces the output speed and increases the output torque. After the motor 22 is started, the gear 26 can be driven to rotate through the transmission of the reducer 23, and then the gear 26 is meshed with the gear ring 1, thereby driving the cylinder 3 of the rotary kiln to rotate.
[0021] See also Figure 3The gear member 13 is composed of a tooth 13-1 and an insert 13-2. The insert 13-2 is located below the tooth 13-1. The shape of the insert 13-2 is the same as the shape of the slot 11-1. A through second mounting hole 13-3 is provided on the side of the insert 13-2. The circular hole radius of the second mounting hole 13-3 is the same as the circular hole radius of the first mounting hole 12-1 on the second positioning ring 12. When the insert 13-2 of the gear member 13 is inserted into the slot 11-1 on the first positioning ring 11, the first mounting hole 12-1 on the second positioning ring 12 will be aligned with the second mounting hole 13-3 on the gear member 13. The bolt 14 of the device uses a partially threaded bolt. The screw radius of the bolt 14 is equal to the circular hole radius of the first mounting hole 12-1 and equal to the circular hole radius of the second mounting hole 12-1. The circular hole radius of the mounting hole 13-3, the screw length of the bolt 14 is greater than the overall thickness of the first positioning ring 11 and the two second positioning rings 12, the transmission of a section of the screw without thread on the bolt 14 is less than the overall thickness of the first positioning ring 11 and the two second positioning rings 12, and the gear part 13 can be fixed by passing the bolt 14 through the first mounting hole 12-1 and the second mounting hole 13-3 in cooperation with the nut 15. A rubber pad 13-4 is attached to each side of the plug-in 13-2, and the width of the tooth 13-1 is equal to the width of the plug-in 13-2 and equal to the spacing between the two second positioning rings 12. After the plug-in 13-2 is inserted into the slot 11-1, the rubber pad 13-4 will be padded between the plug-in 13-2 and the second positioning ring 12, so that the gear part 13 is fixed more firmly.
[0022] The working principle and use process of the utility model are as follows: when the rotary kiln driving device is used, the motor 22 is started, and the gear 26 can be driven to rotate through the transmission of the reducer 23, and then the gear 26 is meshed with the gear ring 1 to drive the barrel 3 of the rotary kiln to rotate. When the gear on the gear ring 1 is damaged, the motor 22 and the rotary kiln are turned off. After the barrel 3 of the rotary kiln stops and the temperature is lowered, the damaged gear part 13 is found, the bolts 14 and nuts 15 for fixing the gear part 13 are screwed off, the damaged gear part 13 is disassembled, and the plug-in 13-3 of the new gear part 13 is inserted into the slot 11-1, and then the gear part 13 is fixed with the bolts 14 and nuts 15. The gear part 13 is replaced simply and conveniently, and the gear ring 1 can be reused after the gear part 13 is replaced, thereby reducing the replacement cost after the gear ring teeth are damaged.
[0023] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
