Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of conical motor, specifically relates to a conical motor with bidirectional braking structure. BACKGROUND

[0002] Double-head conical motor is a special designed motor, its structure and working principle are similar to ordinary conical motor, but have the characteristics of double head, that is, can contain two output shafts or two working ends.

[0003] Double-head conical motor is mainly composed of stator, rotor, bearing, speed reducer (if needed), shaft coupling (connecting load) and the like. Among them, the stator and rotor are conical design, the stator is fixed and is composed of iron core and coil, and is used for generating rotating magnetic field; the rotor can rotate under the action of magnetic field and output mechanical energy.

[0004] When double-head conical motor is used in complex environment with more dust, such as construction site or industrial manufacturing site, dust is easy to invade the bolt connection between motor output shaft and driving part. With the passage of time, thick dust layer will accumulate on the surface of bolt. When double-head conical motor needs to be repaired due to failure, the existence of dust increases the difficulty of disassembly. Because dust not only covers bolt, but also can penetrate into connection gap, bolt is easy to be abraded in the process of disassembly. Such abrasion not only affects disassembly efficiency, but also can weaken the stability of connection after assembly, thereby bringing potential safety hazard to subsequent use of motor.

[0022] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the scope of protection of the utility model. EMBODIMENT

[0023] Referring to Figures 1-5 The utility model provides the following technical scheme: a kind of conical motor with bidirectional braking structure, including conical motor body 1, output shaft 2, shell 3 and power cord 4, output shaft 2 is connected at the both ends of conical motor body 1, power cord 4 is connected in the inside of shell 3, shell 3 is integrally connected on the surface of conical motor body 1, the both ends of conical motor body 1 are connected with fixed block 5, the front end of fixed block 5 is connected with protective block 6, the upper and lower outer side wall of fixed block 5 is integrally connected with lug 7, threaded rod 8 is installed in the inside of lug 7, bearing 9 is installed in one end of threaded rod 8, threaded sleeve 10 is screw-connected on the surface of threaded rod 8.

[0024] In preferred embodiment: threaded rod 8 is rotatably connected between bearing 9 and lug 7.

[0025] In preferred embodiment: threaded sleeve 10 is the same size as the internal cavity of lug 7, and the bottom end of threaded sleeve 10 is connected to the top surface of protective block 6.

[0026] In preferred embodiment: protective block 6 is screw reciprocally connected between threaded sleeve 10 and threaded rod 8 and fixed block 5.

[0027] In preferred embodiment: the front end of protective block 6 has the same size as the diameter of output shaft 2.

[0028] In preferred embodiment, double-head conical motor works with two output shafts 2, and the two output shafts 2 work to form bidirectional braking structure.

[0029] In addition, by rotating threaded rod 8, it smoothly rotates inside lug 7 along the inner ring of bearing 9, which drives threaded sleeve 10 to move along the thread track on the surface of threaded rod 8. At the same time, the movement of threaded sleeve 10 further drives protective block 6 to smoothly move out of the inside of fixed block 5 until it is close to and covers the bolt hole of output shaft 2. This ingenious design ensures that the double-head conical motor can effectively block dust from entering the bolt connection or covering the bolt when it operates in a complex environment with a lot of dust. Therefore, when the double-head conical motor needs to be repaired, it can avoid the problem of reduced disassembly efficiency caused by dust accumulation, and also prevent the problem of weakened connection stability caused by dust abrasion on the surface threads of the bolt.

[0030] It is worth noting that output shaft 2 and driving member are pre-fastened in the bolt hole of output shaft 2 by bolt, and the head of the bolt is ensured not to exceed the surface of output shaft 2, so as to avoid the obstruction of protective block 6 during movement and ensure that it can smoothly cover the bolt connection. Embodiment

[0031] Referring to Figures 1-5The outer side wall of the shell 3 is provided with a "H" shaped connecting block 11, and a through hole is formed in the surface of the connecting block 11 for the power cord 4 to pass through.

[0032] In the preferred embodiment, a sealing ring 12 is mounted on the inner wall of the through hole of the connecting block 11, and the sealing ring 12 is made of food-grade rubber.

[0033] In the preferred embodiment, the sealing ring 12 is tightly fitted with the connecting block 11, so that the power cord 4 is effectively sealed after passing through the connecting block 11, and the small gap between the connecting block 11 and the power cord 4 is effectively sealed. At the same time, the design of the connecting block 11 also avoids the friction that may occur when the power cord 4 directly passes through the shell 3, thereby preventing the surface insulation layer of the power cord 4 from being damaged due to friction. This design further enhances the dustproof effect, effectively prevents dust from entering the double-head conical motor through the gap, and ensures the normal operation of the double-head conical motor in a dusty environment without any interference. The connecting block 11 can be made of transparent plastic material.

[0034] In summary, these designs collectively improve the reliability and durability of the double-head conical motor in complex environments.
