Description

Technical Field

[0001] This utility model relates to the field of speed reducer technology, and in particular to a horizontal speed reducer. Background Technology

[0002] A speed reducer is an independent, closed transmission device between a prime mover and a working machine. It is used to reduce speed and increase torque to meet work requirements. In some cases, it is also used to increase speed, and is called a speed increaser. A speed reducer is a relatively precise machine. Its purpose is to reduce speed and increase torque. It is widely used in modern machinery.

[0003] Existing reducers, such as the horizontal concrete mixer reducer disclosed in announcement number CN206830773U, have a threaded and removable oil tank at the top of the reducer, which contains lubricating oil for gear lubrication. This allows for automatic dripping of lubricating oil to lubricate the two gears, reducing frictional resistance and extending gear life. However, the reducer generates multiple forces and experiences multi-directional vibration during operation. Existing reducers mostly use fixed installation technology, which makes it difficult to maintain stability during frequent vibrations. This not only affects the reduction transmission effect but also makes it easier to cause disconnection between the drive motor and the reducer. Furthermore, existing reducers only have a single heat dissipation vent and a single-sided opening, which is then sealed by a rear cover. The opening size is limited, making it difficult to inspect and maintain the reducer. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figures 1-6 A horizontal speed reducer includes a mounting base 1, a drive motor 4, and a gearbox 5. The mounting base 1 is provided with a buffer section 2, and a support plate 3 for fixing and placing the drive motor 4 and the gearbox 5 is provided on the mounting base 1 through the buffer section 2. See the attached instruction manual for details. Figure 1 With appendix Figure 2 By connecting the drive motor 4 and the reduction gearbox 5, the reduction gearbox 5 has a built-in reducer structure connected to the output end of the drive motor 4, and the reducer is provided with an output shaft extending to the outside of the reduction gearbox 5. The output action of the drive motor 4 is adjusted by the reduction gearbox 5.

[0019] The buffer section 2 includes a first elongated groove 201 located on the left and right sides of the central groove 101, and a second elongated groove 202 located on the front and rear sides of the central groove 101. A first moving member 203 and a second moving member 204 are slidably fitted into the first elongated groove 201 and the second elongated groove 202, respectively. A first spring 205 is welded to the first moving member 203, and a first crooked clamp 206 is fixedly connected to the first spring 205. A second spring 208 is welded to the second moving member 204, and a second crooked clamp 209 is fixedly connected to the second spring 208. A buffer plate 211 is fixedly fitted into the first crooked clamp 206 and the second crooked clamp 209. It is worth noting that: First, when the drive motor 4 and the reduction gearbox 5 generate a forward and backward force, the first moving part 203 moves forward and backward, which in turn drives the second springs 208 on the front and rear sides to perform extension and retraction movements. Second, when the drive motor 4 and the reduction gearbox 5 generate a forward and backward force, the second moving part 204 moves left and right, which in turn drives the first springs 205 on the left and right sides to extend and retract.

[0020] The upper end face of the buffer plate 211 is welded with a third spring 212 that is fixedly connected to the support plate 3. When the drive motor 4 and the reduction gearbox 5 generate a vertical force, the buffer plate 211 applies pressure to the third spring 212 so that it can reciprocate in the vertical direction.

[0021] The gearbox 5 includes a housing 501 fixedly connected to the output end of the drive motor 4. A right-angle cover plate 502 is movably mounted on the housing 501. A spring bolt 503 is provided in the housing 501 to abut against and fix the right-angle cover plate 502. An air inlet window 504 is provided at the bottom of the housing 501, and an air outlet window 505 is provided in the right-angle cover plate 502. An inclined double-layered baffle 506 is fixedly installed in the air outlet window 505. It should be noted that the gearbox 5 has notches corresponding to the two sides of the housing 501 to provide sufficient visibility for maintenance and protection of the housing 501. By providing an inclined air outlet window 505, which has a flared structure that is larger inside and smaller outside, the high-temperature hot air in the housing 501 can be accelerated out through the air outlet window 505. At the same time, the double-layered baffle 506, which has a filtering function, can reduce dust entry and pollution.

[0022] The mounting base 1 has a central groove 101 for mounting the buffer part 2, so that the buffer part 2 can be installed in the central groove 101. The mounting base 1 also has through holes 102 at each of its four corners for mounting locking bolts, so as to fix the mounting base 1.

[0023] The first long groove 201 is set horizontally in the front and back direction, and the second long groove 202 is set horizontally in the left and right direction.

[0024] A first guide rod 207 is integrally connected to the first chamfered clamp 206 and slidably fitted in the first moving part 203. A second guide rod 210 is integrally connected to the second chamfered clamp 209 and slidably fitted in the second moving part 204. A third guide rod 213 is integrally connected to the lower end of the bearing placement plate 3 and slidably fitted in the buffer plate 211. This ensures that the first spring 205, the second spring 208 and the third spring 212 can maintain a straight shape during the extension and retraction process, and prevents the buffer plate 211 and the bearing placement plate 3 from tilting due to buffer movement.

[0025] The first guide rod 207 is fitted into the first spring 205, the second guide rod 210 is fitted into the second spring 208, and the third guide rod 213 is fitted into the third spring 212.

[0026] It should be noted that the specific models and specifications of the drive motor 4 and the gearbox 5 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be elaborated here.

[0027] The functional principle of this utility model can be explained through the following operation methods: When the drive motor 4 and the gearbox 5 generate a horizontal force during operation, the first moving part 203 and the second moving part 204 move back and forth in a straight line along the first long groove 201 and the second long groove 202 respectively. When they generate a vertical force, the buffer plate 211 moves up and down back and forth due to the third spring 212. During operation, the drive motor 4 and the gearbox 5 are connected by a low-temperature cold airflow through the air inlet window 504, and the high-temperature hot airflow inside the gearbox 5 is discharged through the air outlet window 505.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
