[0001] The utility model relates to the technical field of reducers, in particular to a reducer with an output support. Background Art

[0002] A reducer is an independent component consisting of a gear transmission, worm transmission, or gear-worm transmission enclosed in a rigid housing. It is often used as a reduction transmission device between the prime mover and the working machine and is widely used in modern machinery.

[0003] Traditional reducers directly transmit power to external mechanisms through the output shaft, which is prone to breakage due to excessive radial load. Therefore, existing reducers generally add special output supports to provide protection and stability when connected to other equipment or transmission components. However, the existing output supports still have some problems when in use. In particular, the output supports need to be installed tightly during protection, and the inner wall collides and rubs with the transmission shaft, which are prone to mutual wear and reduce the service life. In addition, traditional maintenance requires overall disassembly and the addition of lubricating oil, which is more cumbersome, less convenient to use, and has a low maintenance effect.

[0004] To this end, we propose a reducer with an output support to solve the above problems. Utility Model Content

[0029] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0030] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0031] A reducer with an output support provided by some embodiments of the present invention will be described below with reference to the accompanying drawings.

[0032] Example 1:

[0033] Combine Figures 1-4 As shown, the utility model provides a reducer with an output support.

[0034] Specifically, it includes a reducer body 1 and a transmission shaft 3. The right front end of the reducer body 1 is located on the outside of the transmission shaft 3 and is sleeved with an extended protective sleeve 4. A support sealing cover plate 2 is embedded between the inner side of the front end of the extended protective sleeve 4 and the outer side of the transmission shaft 3. The outer side surface of the transmission shaft 3 is located on the inner side surface of the support sealing cover plate 2 and is annularly provided with an arc-shaped card groove 14. The arc-shaped card groove 14 is mainly used to facilitate the various components in the supporting sealing cover plate 2 to squeeze and stabilize the transmission shaft 3, and at the same time does not hinder the rotation of the transmission shaft 3. The inner sides of the support sealing cover plate 2 are symmetrically provided with installation slots 5, and the inner side surfaces of the installation slots 5 slide The dynamic card is connected with an extrusion push plate 6, which is mainly achieved by elastically squeezing the springs 9 on the outside of the multiple extrusion hollow columns 10, and making the arc-shaped compression airbag cushion 15 on the outside of the arc-shaped top plate 13 embedded in the arc-shaped card groove 14, and reducing the vibration of the force generated by the transmission shaft 3. One end of the extrusion push plate 6 is connected to the arc-shaped top plate 13, and the arc-shaped top plate 13 mainly supports the arc-shaped compression airbag cushion 15. One end of the arc-shaped top plate 13 is located on the inner side of the arc-shaped card groove 14 and is connected to the arc-shaped compression airbag cushion 15. The support sealing cover plate 2 is symmetrically embedded with oil storage boxes at both ends of the inner side surface near the extended protective sleeve seat 4. 7. One end of the oil storage box 7 is located inside the installation slot 5 and is penetrated by a plurality of extruded hollow rods 10. The extruded hollow rods 10 facilitate the installation of the spring 9 and cooperate with the installation slot 5 to limit and stabilize the extruded push plate 6. At the same time, it also plays a role in conducting lubricating oil. The outer sides of the plurality of extruded hollow rods 10 are sleeved with springs 9. The other end of the extruded push plate 6 is slidably connected to the outer side of one end of the plurality of extruded hollow rods 10, and the outer side surface of the other end of the extruded push plate 6 is in contact with the outer side surface of one end of the spring 9. One side of the arc-shaped compression airbag cushion 15 is close to the inner side of the arc-shaped slot 14, extending the protective sleeve seat 4. The left and right side ends are symmetrically penetrated with fixed locking bolts 8. The fixed locking bolts 8 are mainly used to facilitate the threaded locking of the oil storage box 7 in the extended protective sleeve seat 4 and the support sealing cover plate 2. At the same time, they also play a sealing role. After disassembly, it is also convenient to directly inject lubricating oil without complete disassembly. One end of the fixed locking bolt 8 extends through and seals the outside of the two ends of the oil storage box 7. A sealing protection plug gasket 12 is embedded between the embedded parts of the extended protective sleeve seat 4 and the support sealing cover plate 2. The sealing protection plug gasket 12 has a certain sealing protection effect to prevent mutual friction and wear between the extended protective sleeve seat 4 and the support sealing cover plate 2.

[0035] Example 2:

[0036] Combine Figure 3-Figure 4 As shown, based on the first embodiment,

[0037] Specifically, a compression oil injection rubber sleeve 16 is installed between the extrusion push plate 6 and the plurality of extrusion hollow columns 10 slidingly abutting each other. The compression oil injection rubber sleeve 16 is mainly subjected to the back and forth extrusion between the extrusion push plate 6 and the extrusion hollow column 10 to generate a back and forth compression force, and the lubricating oil is input and output through the oil-absorbing cotton 11 back and forth for lubrication. An oil guide hole 17 is provided between the connection between the compression oil injection rubber sleeve 16, the extrusion push plate 6, the arc-shaped top plate 13 and the arc-shaped compression airbag cushion 15. The oil storage box 7, the compression oil injection rubber sleeve 16, the arc-shaped top plate 13 and the arc-shaped compression airbag cushion 15 are connected to each other. The interior of the airbag cushion 15 is filled with oil-absorbing cotton 11. The oil-absorbing cotton 11 not only transports the lubricating oil, but also cooperates with the back-and-forth compression of the compression oil-filling sleeve 16 to prevent leakage, preventing excess lubricating oil from being completely injected into the arc-shaped groove 14 and directly overflowing into the reducer body 1, causing blockage and pollution, and forming an intermittent lubrication effect. The oil-absorbing cotton 11 also extends to fill the interior of the oil guide hole 17. The oil storage box 7, multiple extruded hollow columns 10, compression oil-filling sleeve 16, arc-shaped top plate 13, arc-shaped compression airbag cushion 15 and arc-shaped groove 14 are all interconnected through the oil guide hole 17.

[0038] The working principle and usage process of the present invention are as follows: First, when the reducer body 1 is operating as a whole, the vibration generated by the rotation of the transmission shaft 3 causes the force to be transmitted to the arc-shaped compression airbag cushion 15 and squeezes the push plate 6 so that the spring 9 is squeezed, and its elastic force slows down its vibration squeezing force. At the same time, it reduces direct contact with the inner wall of the support sealing cover plate 2 and reduces wear. Secondly, through the elastic force of the above-mentioned spring 9, the compression oil injection rubber sleeve 16 between the squeeze push plate 6 and multiple springs 9 is squeezed and continuously compressed, and the lubricating oil inside the oil storage box 7 is transported to the inside of the compression oil injection rubber sleeve 16 through the spring 9, and is successively transported and transmitted through the compression oil injection rubber sleeve 16, the oil guide hole 17, the arc-shaped top plate 13 and the oil-absorbing cotton 11 inside the arc-shaped compression airbag cushion 15 to the inside of the arc-shaped slot 14 to lubricate and protect the transmission shaft 3.

[0039] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
