Description

Technical Field

[0001] The utility model relates to the technical field of motor transmission output structure, in particular to a motor transmission mechanism in which a motor and a reducer are integrated. Background Art

[0002] The patent with application number CN202223157265.1 discloses a starting transmission gear structure for a reduction motor, including a sealed shell, a connecting rotating plate is installed on one side of the interior of the sealed shell, a transmission chamber is opened inside the sealed shell and next to the connecting rotating plate, and a main rotating gear is installed inside the transmission chamber and relative to the connecting rotating plate. The utility model is provided with a sealed shell, a first groove and a blocking plate, etc. When the transmission gear rotates, the blocking plate is driven to rotate inside the first groove through the connecting shaft. After entering the first groove, external dust is blocked by the blocking plate and cannot enter the interior of the transmission chamber, thereby reducing the contact between dust and gears, and solving the problem that the transmission gear structure is directly exposed to the outside and the dust and impurities on the surface will accelerate the wear of the gear surface when rotating and doing work.

[0003] However, in actual use, this technical solution is generally achieved by modifying different reduction motors when different speeds need to be met, which is very troublesome and complicated under some rapid production requirements. The current reduction motor assembly cannot quickly meet the changing requirements of different speeds. In addition, the transmission structure of the motor will wear and dust after long-term use, and the traditional motor transmission structure is not easy to disassemble quickly, making it difficult to quickly maintain the wear between the reduction gear assemblies. Utility Model Content

The electric telescopic cylinder is provided to drive the spline gear sleeve to be plugged and engaged with different second reduction gear groups, thereby changing the speed effect during actual use.

[0026] Embodiment 1

[0027] like Figure 1As shown, this embodiment provides a motor transmission mechanism in which a motor and a reducer are combined into one body, including a motor body 1 and a protective shell 2, the protective shell 2 is fixedly connected to one side of the motor body 1, the protective shell 2 provides a dustproof effect, a plurality of first reduction gear groups 3 are movably connected to the inner side of the protective shell 2, and the first reduction gear group 3 is movably connected to the output shaft of the motor body 1 through a sleeve, the first reduction gear group 3 is directly connected to the motor body 1 to maintain the transmission effect, a plurality of second reduction gear groups 4 are meshed at the bottom of the first reduction gear group 3, a limited position mounting frame 5 is arranged at the bottom of the second reduction gear group 4, and a limited position mounting frame 5 is arranged at the bottom of the second reduction gear group 4. The mounting frame 5 realizes the meshing and installation docking between the reduction gear groups, and the second reduction gear group 4 is movably connected to the protective shell 2 through the limit mounting frame 5. The bottom of the limit mounting frame 5 is fixedly connected with two sets of oppositely distributed separation mechanisms 6. The separation mechanism 6 can drive the mounting frame 5 to have a movable disassembly effect on the inner side of the protective shell 2. The inner side of the second reduction gear group 4 is movably connected with a control mechanism 7. The control mechanism 7 can change the actual output end under the drive, so as to reduce or increase the actual speed effect. The bottom of the separation mechanism 6 is fixedly connected with a sliding plate 8, and the sliding plate 8 is slidably connected to the protective shell 2.

[0028] like Figure 3 and Figure 6 As shown, the control mechanism 7 includes an electric telescopic cylinder 701, a connecting frame 702, a resistance ring 703, a spline output rod 704, a spline gear sleeve 705 and a plug-in slot 706. The connecting frame 702 is fixedly connected to the output rod of the electric telescopic cylinder 701, the resistance ring 703 is fixedly connected to one end of the connecting frame 702, the spline gear sleeve 705 is sleeved on the surface of the spline output rod 704, and the spline gear sleeve 705 and the spline output rod 704 are slidably connected. Here, the spline gear sleeve 705 can slide laterally on the surface of the spline output rod 704, and at the same time, it can drive the spline output rod 704 to rotate under the action of the transmission force to achieve a basic transmission effect. The resistance ring 703 is located on one side of the spline gear sleeve 705, and the spline gear sleeve 705 is plugged into the plug-in slot 706. The plug-in slot 706 is provided on the inner side of the second reduction gear set 4, and the plug-in slot 706 realizes the connection between different second reduction gear sets 4 and the spline gear sleeve 705. The cross section of the plug-in slot 706 is convex, and the spline output rod 704 passes through several sets of second reduction gear sets 4. The spline gear sleeve 705 is provided with a sliding protrusion on the side close to the contact ring 703, and the function of the sliding protrusion here is to prevent the situation that the spline gear sleeve 705 cannot be pulled when the contact ring 703 retracts, and the spline gear sleeve 705 is rotatably connected with the contact ring 703 through the sliding protrusion, and the inner diameter size of the contact ring 703 is larger than the outer diameter size of the spline output rod 704, and the outer diameter size of the contact ring 703 is smaller than the inner diameter size of the plug-in slot 706. The precise size requirement enables the contact ring 703 to move normally between the spline output rod 704 and the second reduction gear set 4.

[0029] like Figure 4 and Figure 5 As shown, the separation mechanism 6 includes a pull rod 601, a pull ring 602, two sets of sliding blocks 603, a stress spring 604, two sets of support rods 605, a clamp 606 and a clamp plate 607. The pull ring 602 is fixedly connected to one end of the pull rod 601, and the two sets of sliding blocks 603 are slidably connected to the left and right ends of the pull rod 601 respectively. The stress spring 604 is sleeved on the surface of the pull rod 601. The stress spring 604 achieves the effect of resisting the sliding block 603 through the pull rod 601, thereby bringing The two groups of support rods 605 are moved to contact the limit mounting frame 5 and the sliding plate 8, ensuring a good meshing transmission effect between the first reduction gear group 3 and the second reduction gear group 4, and the sliding block 603 is elastically connected to the pull rod 601 through the stress spring 604, and the two groups of support rods 605 are respectively movably connected to the upper and lower ends of the sliding block 603 through the rotating pin, and the clamping member 606 is fixedly connected to the end of the pull rod 601 away from the pull ring 602, and the clamping member 606 is clamped with the clamping plate 607. The clamping member 606 is then pushed by the pull rod 601 to enter the inner side of the clamping plate 607, and then the pull rod 601 is rotated to achieve the locking effect of the clamping member 606 and the clamping plate 607, preventing the pull rod 601 from being separated by the stress spring 604, and the pull rod 601 is movably connected to the opposite side of the limit mounting frame 5 and the sliding plate 8 through the limit seat, and the clamping plate 607 is fixedly connected to the bottom of the limit mounting frame 5. The ends of the two groups of support rods 605 away from the sliding block 603 are movably connected to the limit mounting frame 5 and the sliding plate 8 through a rotating pin, and the angle between the two groups of support rods 605 is acute. The acute-angled support rods 605 can provide better resistance force to the upper and lower ends after being subjected to force, thereby ensuring the distance between the limit mounting frame 5 and the sliding plate 8.

[0030] Working steps

[0031] Step 1, first control the electric telescopic cylinder 701 in the mechanism 7 to drive, and under the connection of the connecting frame 702, drive the resistance ring 703 and the spline gear sleeve 705 to slide on the surface of the spline output rod 704, so that the spline gear sleeve 705 is plugged into the plug-in groove 706 in the different second reduction gear groups 4. At this time, the first reduction gear group 3 can directly drive the spline gear sleeve 705 to rotate under the transmission effect of the motor body 1, thereby realizing the ultimate transmission at the specified position and changing the actual required speed.

[0032] Step 2: When maintenance is required on the second reduction gear group 4 or the first reduction gear group 3, the pull rod 601 is rotated to unlock the clamping piece 606 and the clamping plate 607. Then, under the elastic action of the stress spring 604, the sliding block 603 slides on the surface of the pull rod 601. At this time, the support rods 605 at the upper and lower ends of the sliding block 603 are loosened, and the limiting mounting frame 5 and the sliding plate 8 can be relatively close to each other. In this way, the sliding plate 8 can be pulled to realize the overall disassembly of the second reduction gear group 4, which is convenient for actual maintenance work.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
