AI Technical Summary
The box and base of the existing worm gear reducer are cast in one piece, which makes it difficult to control the installation rigidity and accuracy of the output shaft, especially in high-frequency vibration environments, which affect the stability and life of the output shaft.
The left and right end covers are separated from the box. The base is cast in one piece at the bottom of the left and right end covers, and a bearing mounting step is set on the inner wall. The bearing supports the output shaft. The output shaft passes through the end cover hole. The worm engages the worm wheel. The box is suspended between the two end covers to enhance the support rigidity and stability of the output shaft.
Improves the installation rigidity and accuracy of the output shaft, ensuring stability and service life in high-frequency vibration environments.

Abstract
Description
Technical Field
[0001] The utility model relates to a reducer, in particular to a reducer with stable support. Background Art
[0002] The existing worm gear reducer has a housing and a base cast as one piece. The accuracy of the motor power input and the output shaft power output is directly affected by the end cover, making it difficult to control the output accuracy. In addition, the rigidity of the housing installed through the base cannot ensure the installation rigidity of the output shaft, resulting in the inability to stably control the support stability of the output shaft. In high-frequency vibration applications, the accuracy and life of the output shaft are greatly affected. Summary of the Invention
[0003] The utility model provides a speed reducer with a simple structure and a stable support capable of effectively ensuring the installation and use of an output shaft with rigidity and precision.
[0004] The technical solution adopted by the utility model is: a stably supported reducer, characterized in that: it comprises left and right end covers and a box body, the bottom of the left and right end covers are integrally cast into a base, a mounting hole is provided on the base, the inner side walls of the left and right end covers are provided with a bearing mounting step, the bearing mounting step supports the output shaft through a bearing, the output shaft passes through the outlet hole on the left end cover or the outlet hole on the right end cover, the box body is cylindrical, the left and right mouth ends of the box body are respectively connected to the left and right end covers through bolts, the front and rear inner walls of the box body are provided with a bearing mounting step, the bearing mounting step is connected to a worm through a bearing, and the worm meshes with the worm wheel connected to the output shaft.
[0005] End cover holes are provided on the front and rear inner walls of the box body, and the worm is supported by bearings in the bearing installation steps that seal the inner walls of the end cover holes.
[0006] A multi-layer mechanical seal is installed between the output shaft and the outlet hole.
[0007] The utility model forms the end cover and the base in one piece, the output shaft passes through the end cover, and the box body is suspended between the two end covers, which can effectively ensure the rigidity and stability of the output shaft support and is conducive to improving the installation and output accuracy. BRIEF DESCRIPTION OF THE DRAWINGS
[0008] Figure 1 This is a schematic structural diagram of the utility model.
[0009] In the figure: left end cover 1, right end cover 2, base 3, box body 4, bearing mounting step 5, cylindrical roller bearing 6, mechanical seal 7, output shaft 8, worm gear 9, worm 10, box body end cover 11. DETAILED DESCRIPTION
[0010] The following is further explained with reference to the accompanying drawings.
[0011] Figure 1 As shown: A stably supported reducer includes a left end cover 1, a right end cover 2, a base 3, a housing 4, a bearing mounting step 5, a cylindrical roller bearing 6, a mechanical seal 7, an output shaft 8, a worm gear 9, a worm 10, and a housing end cover 11. The base 3 is integrally cast at the bottom of the left and right end covers 1 and 2, and a mounting hole is provided on the base 3. The inner side walls of the left and right end covers 1 and 2 are provided with a bearing mounting step 5. The output shaft 8 is supported by a cylindrical roller bearing 6 in the bearing mounting step 5. The output shaft 8 passes through the upper hole of the left end cover through the mechanical seal 7. The output shaft 8 is connected to the worm gear 9 through a key. The worm gear 9 engages with the worm 10. The housing 4 is cylindrical. The left and right opening ends of the housing 4 are respectively connected to the left and right end covers 1 and 2 by bolts. End cover holes are provided on the front and rear inner walls of the housing 4. The end cover holes are covered with end covers 11. The worm 10 is supported by a bearing in the bearing mounting step on the inner wall of the end cover hole.
