Description

Technical Field

[0001] The utility model belongs to the technical field of reducers, and in particular relates to a reducer housing. Background Art

[0002] The reducer is an independent closed transmission device between the prime mover and the working machine, which is used to reduce the speed and increase the torque to meet the working needs. In some cases, it is also used to increase the speed, which is called a speed increaser.

[0003] The stability of the reducer output depends on the stability of the output shaft output. In order to ensure the stability of the output shaft rotation, existing reducers often set the reducer housing to an integrated structure. Although the output shaft can be restricted by the housing to ensure the stability of the output shaft rotation, it undoubtedly increases the use cost of the reducer housing, which in turn leads to an increase in the use cost of the reducer.

[0004] How to design a reducer housing and how to reduce the cost of using the reducer have become issues that need to be solved urgently. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a reducer housing to solve the problem of high cost of using the reducer in the prior art.

[0006] To achieve the above object, the utility model provides a reducer housing, comprising a housing, wherein the housing is provided with an axial through hole, a wear-resistant ring is embedded in the axial through hole, a coupling column is integrally connected to the top of the wear-resistant ring, the top end of the coupling column passes upward to the top surface of the housing, and a first mounting hole is provided at the top end of the coupling column;

[0007] The coupling column is located inside the side wall of the shell.

[0008] By adopting this technical solution: the reducer housing is divided into two parts, the shell and the wear-resistant ring. The wear-resistant ring increases the strength of the shaft hole position to avoid wear at the contact position between the shell and the output shaft. At the same time, the connecting column on the wear-resistant ring can fix the motor and the wear-resistant ring when the reducer is connected to the motor, ensuring the position stability of the motor itself, the shell and the wear-resistant ring after the motor is connected to the reducer. The problem of the shell being damaged by excessive force from the wear-resistant ring will not occur, and the shell strength requirement is reduced. In this way, while ensuring the stability of the reducer output, the manufacturing and use costs of the entire reducer housing can be reduced, thereby reducing the use cost of the reducer.

[0009] In one embodiment of the present invention, the length of the wear-resistant ring is greater than the width of the side wall of the housing, and the two ends of the wear-resistant ring extend out of the interior of the housing side wall by the same length;

[0010] By adopting this technical solution: increasing the length of the wear-resistant ring to increase the restriction on the output shaft passing through, and increasing the rotational stability of the output shaft inside the wear-resistant ring; the lengths of the two ends of the wear-resistant ring extending out of the side wall of the shell are the same, which can ensure the stability of the wear-resistant ring on the shell and ensure uniform force distribution, thereby reducing the possibility of the shell being damaged by the force of the wear-resistant ring.

[0011] In one embodiment of the present invention, pillars are integrally connected to both sides of the wear-resistant ring, and the pillars extend into the side wall of the shell;

[0012] By adopting this technical solution: the contact area between the wear-resistant ring and the side wall of the shell is increased by adding pillars, thereby increasing the stability of the wear-resistant ring on the shell.

[0013] In one embodiment of the present invention, the bottom end of the housing is connected to a base, and a second mounting hole is formed at a corner of the base;

[0014] By adopting this technical solution: a base is added to provide bottom support, and a second mounting hole is opened to facilitate the connection between the base and the working support surface.

[0015] In one embodiment of the present invention, a countersunk hole is provided at a corner of the base corresponding to the upper side of the second mounting hole;

[0016] By adopting this technical solution: after the countersunk hole is opened, the top of the screw connected through the second mounting hole will not protrude from the top surface of the base to affect other components.

[0017] In one embodiment of the present invention, the top of the housing is connected to a top seat, the first mounting hole is correspondingly arranged on the inner side of the top seat, and the top surface of the top seat is parallel to and higher than the surface where the top of the first mounting hole is located;

[0018] By adopting this technical solution: the top seat provides a motor installation position, and after the motor is connected to the first mounting hole through screws, it will be pressed against the top surface of the top seat, so that the motor, housing and wear-resistant ring are relatively fixed, ensuring the stability of the overall structure.

[0019] In an embodiment of the present invention, the shell is made of plastic.

[0020] By adopting this technical solution: the cost of using plastic materials is low, which can directly reduce the cost of using the reducer. At the same time, compared with the existing integrated housing, it has corrosion resistance and oxidation resistance, and can adapt to the use of reducers in special environments.

[0021] Beneficial effects

[0022] In the structure of the utility model, the reducer casing is divided into two parts, a shell and a wear-resistant ring. The wear-resistant ring provides strength for the output shaft rod passing through the position, thereby ensuring the stable output of the output shaft rod while reducing the strength requirement of the shell, thereby reducing the manufacturing cost of the shell, and further reducing the use cost of the entire reducer; the wear-resistant ring can be relatively fixed to the motor when the reducer is connected to the motor, ensuring the stability of the wear-resistant ring itself while reducing the influence between the wear-resistant ring and the shell, so that the shell can be replaced with a low-cost corrosion-resistant material, reducing the use cost of the reducer while adapting to the use requirements of the reducer in special environments; the promotion and application has good economic and social benefits.

[0029] like Figure 1-3The top of the connecting post 6 is passed through the top surface of the housing 1, and the top of the connecting post 6 is provided with a first mounting hole 7; the connecting post 6 is located inside the side wall of the housing 1, dividing the reducer housing into two parts: the housing 1 and the wear-resistant ring 5. The wear-resistant ring 5 increases the strength of the position of the through-axis hole 4 to avoid wear at the contact position between the housing 1 and the output shaft. At the same time, the connecting post 6 on the wear-resistant ring 5 can fix the motor and the wear-resistant ring 5 when the reducer is connected to the motor, ensuring the position stability of the motor itself, the housing 1 and the wear-resistant ring 5 after the motor is connected to the reducer, and the problem of damage to the housing 1 caused by excessive force of the wear-resistant ring 5 will not occur, thereby reducing the strength requirement of the housing 1. In this way, while ensuring the stability of the reducer output, the manufacturing and use costs of the entire reducer housing can be reduced, thereby reducing the use cost of the reducer.

[0030] Both sides of the wear-resistant ring 5 are integrally connected with pillars 8, which extend into the side wall of the shell 1. By adding pillars 8, the contact area between the wear-resistant ring 5 and the side wall of the shell 1 is increased, thereby increasing the stability of the wear-resistant ring 5 on the shell 1.

[0031] The bottom end of the shell 1 is connected to the base 2, and a second mounting hole 9 is opened at the corner position of the base 2. The additional base 2 provides bottom support, and the second mounting hole 9 is opened to facilitate the connection between the base 2 and the working support surface; a countersunk hole 10 is opened above the corner position of the base 2 corresponding to the second mounting hole 9. After the countersunk hole 10 is opened, the top of the screw connected through the second mounting hole 9 will not protrude from the top surface of the base 2 and affect other components.

[0032] The top of the shell 1 is connected to the top seat 3, and the first mounting hole 7 is correspondingly arranged on the inner side of the top seat 3. The top surface of the top seat 3 is parallel to and higher than the top surface of the first mounting hole 7. The top seat 3 provides a motor installation position. After the motor is connected to the first mounting hole 7 by screws, it will be pressed against the top surface of the top seat 3, so that the motor, shell 1 and wear-resistant ring 5 are relatively fixed, ensuring the stability of the overall structure.

[0033] During specific implementation, the internal components of the reducer are installed inside the housing 1, and the output shaft is passed through the wear-resistant ring 5 embedded in the housing 1 to complete the assembly of the reducer. When the reducer is in use, the motor is installed above the top seat 3 of the housing 1, so that the motor and the wear-resistant ring 5 are relatively fixed through the connecting column 6 to complete the overall fixation. When the reducer is running, the motor output shaft outputs power to the input shaft inside the housing 1, and after deceleration by the gear set, the output shaft passes through the wear-resistant ring 5 and outputs power from the inside of the housing 1.

[0034] In summary, the present invention provides a reducer housing, which is divided into a housing 1 and a wear-resistant ring 5. The wear-resistant ring 5 provides strength for the position where the output shaft passes through, thereby ensuring the output stability of the output shaft while reducing the strength requirements of the housing 1, thereby reducing the manufacturing cost of the housing 1 and further reducing the use cost of the entire reducer; the wear-resistant ring 5 can be relatively fixed to the motor when the reducer is connected to the motor, ensuring the stability of the wear-resistant ring 5 itself while reducing the impact between the wear-resistant ring 5 and the housing 1, thereby allowing the housing 1 to be replaced with a low-cost corrosion-resistant material, reducing the use cost of the reducer while adapting to the use requirements of the reducer in special environments; and promoting its application has good economic and social benefits. Therefore, the present invention effectively overcomes the various shortcomings of the existing technology and has high industrial utilization value.

[0035] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed in the present invention are intended to be covered by the claims of the present invention.
