Description

Technical Field

[0001] This utility model relates to a reduction gear motor with a wear detection structure, specifically belonging to the technical field of reduction gear motors. Background Technology

[0002] A geared motor is a combination of a gear reducer and a motor, typically assembled and supplied as a complete set by a specialized gear reducer manufacturer. Geared motors have a wide range of applications and are indispensable power equipment in mechanical equipment, especially in packaging machinery, printing machinery, corrugated machinery, color box machinery, conveying machinery, food machinery, automated parking systems, automated warehousing, automated warehouses, chemical, textile, and dyeing and finishing equipment. They are also widely used in electronic locks, optical equipment, precision instruments, and financial equipment.

[0003] The planetary gears in existing gear reducers will inevitably wear during operation, and it is very inconvenient to check the degree of wear, which can only be judged by experience. However, in emergency situations, if the planetary gears are worn to the limit and people do not replace them in time, the consequences will be very serious. Utility Model Content

[0004] The purpose of this invention is to provide a reduction gear motor with a wear detection structure, so as to ensure that the wear degree of the gear can be checked during operation, and to avoid serious consequences when the wear degree of the gear reaches the limit.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: the new model includes a protective shell and a gear motor, and also includes a drive rod and a wear detection component;

[0006] A gear motor is fixedly installed on the bottom inner side of the protective shell. A drive gear is fixedly installed on the outer side of the output shaft of the gear motor. A reduction gear is meshed with one end of the drive gear. A drive rod is fixedly installed on the inner side of the reduction gear. One end of the drive rod is inserted into a slot opened in the inner side wall of the protective shell. A wear detection component is set on the reduction gear facing the opposite direction of the gear motor.

[0007] Furthermore, the drive is achieved through a geared motor, which in turn drives the drive rod to rotate and output power through the meshing connection between the drive gear and the reduction gear. Finally, a wear detection component is used to check the wear of the reduction gear to prevent serious consequences caused by wear of the reduction gear.

[0008] A connecting plate is fixedly installed on the top surface of the inner side of the protective shell, and a drive rod is connected to the inner side of the connecting plate; a front cover plate is fixedly installed on one side of the protective shell, and the output shaft end of the gear motor is inserted into the slot opened in the inner side wall of the front cover plate, and a drive rod is connected inside the front cover plate.

[0009] Furthermore, the connecting plate improves the stability of the drive rod, and the front cover plate allows for convenient and stable installation of the wear detection component.

[0010] The wear detection assembly includes a detection gear, a limiting tube, a threaded rod, and a wear wheel; the drive rod is provided with a threaded groove, and the drive rod is connected to the detection gear through the threaded groove. The detection gear is provided with a limiting tube, and the threaded rod is connected inside the limiting tube. The wear wheel is connected to the outside of the threaded rod and is located inside the detection gear.

[0011] Furthermore, the wear wheel is installed by cooperating with the limiting tube and threaded rod inside the detection gear, and the wear wheel is used to determine the overall wear degree of the detection gear.

[0012] The wear detection component also includes a baffle and a marker light strip; a baffle is fixedly connected to one end of the threaded rod, the baffle is located outside the detection gear, and a marker light strip is set on the baffle, the marker light strip is set with an arc structure;

[0013] Furthermore, the stability of the wear wheel installation is improved by using a baffle, and the contact between the wear wheels is judged by the rotation and revolution of the indicator light strip, thereby judging the wear condition between the reduction gear and the drive gear.

[0014] The wear detection component also includes an image detector and a light alarm;

[0015] An image detector is fixedly installed on the inner wall of the front cover, and a light alarm is fixedly installed on the outer side of the front cover. The image detector and the light alarm are electrically connected together, and the image detector is set for the corresponding indicator light strip.

[0016] Furthermore, the indicator light strip is detected by an image detector to determine whether it rotates on its own axis while revolving around the sun, thereby determining whether an alarm should be triggered by the light alarm.

[0017] One end of the detection gear is meshed with a drive gear, and the detection gear and the reduction gear are configured to correspond to each other.

[0018] Furthermore, this ensures that the wear levels of the detection gear and the reduction gear are the same, which helps improve the accuracy of wear detection.

[0019] The beneficial effects of this utility model are:

[0020] 1. The structure of the wear wheel rotating inside the detection gear allows the wear wheel to rotate when the detection gear meshes with the drive gear. This allows the wear wheel to rotate on its own axis while revolving around the central axis. At this time, the image detector judges the different light bands formed by the wear wheel and the marker light strip, thereby judging the degree of wear between the detection gear and the drive gear, and thus deducing the degree of wear between the drive gear and the reduction gear, avoiding the problem of severe wear of the reduction gear.

[0029] The following will be combined with the appendix Figure 1-7 The technical solutions in the embodiments are described clearly and completely.

[0030] Specific implementation method one: as follows Figure 1-5 As shown, the device consists of a protective shell 1, a gear motor 2, and a detection gear 7. The gear motor 2 is fixedly installed on the bottom inner side of the protective shell 1 by bolts. The drive gear 3 is fixedly installed on the outer side of the output shaft of the gear motor 2. The upper end of the drive gear 3 is meshed with the reduction gear 4 and the detection gear 7. The detection gear 7 and the reduction gear 4 are of the same size and are correspondingly set, so that the state of the reduction gear 4 can be deduced by the detection gear 7, which helps to improve the accuracy of the detection.

[0031] A connecting plate 6 is fixedly installed on the top surface of the inner side of the protective shell 1. The connecting plate 6 improves the driving stability of the drive rod 5. A front cover plate 8 is fixedly installed on the front side of the protective shell 1 by bolts. The front cover plate 8 allows for convenient and stable installation and replacement of the drive gear 3, reduction gear 4 and detection gear 7, thereby improving the convenience of subsequent use of the device.

[0032] The threaded groove on the drive rod 5 allows the detection gear 7 to be quickly installed on the drive rod 5. The threaded connection between the limiting tube 11 inside the detection gear 7 and the threaded rod 12 allows the wear wheel 13 to be quickly installed. The baffle 14 fixedly connected to one end of the threaded rod 12 improves the stability of the installation of the wear wheel 13. The contact condition between the wear wheels 13 is judged by the rotation and revolution of the marking light strip 15, thereby judging the wear condition between the reduction gear 4 and the drive gear 3.

[0033] Specific implementation method two: such as Figure 6-7 As shown, when the gear motor 2 drives the reduction gear 4 and the detection gear 7 to rotate via the drive gear 3, the drive gear 3 meshes with the reduction gear 4 and the detection gear 7 respectively. Therefore, the drive gear 3 will drive the wear wheel 13, which is set at an equal angle inside the detection gear 7, to rotate. Since the wear wheel 13 is bolted to the outside of the threaded rod 12, and a baffle 14 is fixedly connected to one end of the threaded rod 12, and a marker light strip 15 is set on the baffle 14, the wear wheel 13 can drive the baffle 14 to rotate synchronously via the threaded rod 12. When the baffle 14 rotates, it will drive the marker light strip 15 to rotate. Since the detection gear 7 as a whole is rotating, the marker light strip 15 will rotate on its own axis and revolve around the sun at the same time. At this time, the marker light strip 15 will form a shape like... Figure 7 The halo effect occurs when the drive gear 3 and the detection gear 7 are engaged for an extended period, causing the wear wheel 13 to become unable to rotate. In this case, the marker light strip 15 will only revolve around the detection gear 7 and will not rotate on its own axis. At this point, the marker light strip 15 will form a halo effect. Figure 6 The halo of light is finally determined by the image detector 9 set for the corresponding marker light strip 15 to determine whether the marker light strip 15 is revolving. If the marker light strip 15 is not revolving, the light alarm 10 electrically connected to the image detector 9 will sound an alarm, thereby avoiding the situation where the detection gear 7 is worn and goes unnoticed.
