Structural improvement of the tire removal machine

This creation is about the structural improvement of a tireless machine. In more detail, especially the combination of motor and deceleration into a group, the motor is small in size, no need for large space, and the long output shaft has a long wheelbase at both ends. No need to connect the shaft output, the upper and lower bearing failure rate is low, easy to assemble the integrated motor and the speed reducer, no need to assemble the belt and make the adjustment elastic belt, the force arm of the output shaft is long, the input force is large, and the transmission efficiency is high. The structure of the tire machine is improved.

According to the prior art, as shown in the first and second figures, the conventional wheel tyre changer (1) is mainly composed of a machine table 10, a driving device 11 and a tire removing device 12, wherein the driving device 11 The system is disposed in the machine 10 and is provided with a driving motor 110 and a speed reducer 13. The driving motor 110 drives a pulley 111 and a belt 112. The speed reducer 13 is coupled to the belt 112 of the driving motor 110. The wheel 131 is provided with a rotating shaft 14 extending upwardly from the outside of the machine table 10. The tire removing device 12 is coupled with the driving device 11 and is provided with a dismounting column 15 and a clamping turntable 16 The disassembly column 15 is coupled with the machine table 10, and the clamping disc 16 is sleeved on the rotating shaft 14 of the speed reducer 13 and located below the disassembly column 15; In use, a wheel is mainly fixed on the clamping turntable 16, and the driving wheel 110 of the reducer 13 is driven by the belt 112 of the driving motor 110, so that the rotating shaft 14 of the speed reducer 13 can drive the clip. The holding turntable 16 is rotated relative to the machine table 10 and the disassembly column 15, and at this time, the disassembly column 15 can be passed through As the wheel that rotates the chuck 16 removes its tire, the existing wheel tyre remover can be driven through the drive motor 110 pulley 111 and the belt 112. The manner in which the speed reducer 13 rotates the wheel 131 further produces a deceleration and transmission effect.

It is known that the following problems are caused by the transmission of the pulley 111, the belt 112 and the rotating wheel 131:

1. The manner in which the pulley 111, the belt 112 and the rotating wheel 131 are transmitted is inefficient.

Second, the process of assembling the pulley 111, the belt 112 and the rotating wheel 131 is cumbersome.

3. When assembling, the speed reducer 13 and the belt 112 are assembled first, and then the drive motor 110 is installed, and the tension of the correction belt 112 needs to be adjusted. After using for a period of time, the belt 112 needs to be adjusted.

4. After the driving device 11 is used for a long time, the belt 112 may wear out, thereby causing a situation in which the transmission is inaccurate and an error, and the transmission between the driving motor 110 and the speed reducer 13 generates a certain noise.

In addition, if the pulley 111, the belt 112, and the rotating wheel 131 are not used, a general-purpose reducer is used. As shown in the third and fourth figures, the conventional tire changer (2) is driven by a machine 20 and a motor. The device 201 is composed of a tire removing device 202 and a dismounting column 203. The driving device 201 has a motor shaft 23 for driving a speed reducer 200. The motor shaft 23 has an external gear 231. The speed reducer 200 is provided with two transmission rods 21 and a Each of the transmission rods 21 is provided with a transmission gear 211 and a rotating tooth 212. Each of the transmission rods 21 is provided with a bearing. The rotating rod 22 is provided with a rotating gear 221, and the rotating rod 22 extends outside the reduction gear 200. The outer gear 231 of the motor shaft 23 drives the transmission gear 211 of the transmission rod 21 to synchronously rotate the rotating teeth 212 of the two transmission rods 21, and the rotating teeth 212 rotates the rotating gear 221 to rotate the rotating rod 22.

Although the conventional tire-cutting machine (2) is a direct transmission rotating rod 22, the following defects are also caused:

1. The wheelbase at both ends of the rotating rod 22 is not long enough (the arm is short), and the internal bearing is often damaged.

2. During the tire removal process, the hand rotates the tire, the motor shaft 23 and the speed reducer 200 are not in a straight state state device, and the speed reducer 200 follows the tire rotation, which is easily damaged and has a high failure rate.

3. The rotating rod 22 (output shaft) of the speed reducer 200 needs to be connected with an upper sleeve, and the upper sleeve is connected with the tire removing device 202, and the assembly procedure is high and the cost is high.

Therefore, both the pulley and the universal reducer have their own missing. Although the universal reducer does not use the belt, the use of the pulley can be improved, but the wheelbase is not long enough, the internal bearing is often damaged, the failure rate is high, etc. Missing.

In view of this, the creators of this case are still actively working on development, research and improvement, and constantly experimenting with assembly and accumulating experience, and finally have a creation that can solve the above drawbacks.
