Description

Technical Field

[0001] This utility model belongs to the field of forklift motor technology and relates to an installation structure for a forklift motor. Background Technology

[0002] In order to facilitate suspension when driving the forklift wheels, the mounting structure of the forklift motor usually has a cantilever fixed to the outside of the motor housing. The cantilever is fixed to the forklift to facilitate motor installation.

[0003] For example, Chinese patent application [Authorization Announcement No.: CN111186288B] discloses a drive structure for the drive wheel of an electric vehicle, including a drive motor and a drive wheel. As can be seen from the drawings in the specification of the document, a cantilever is provided on the outer casing of the motor housing of the drive motor. The cantilever is fixed radially to the motor housing by fasteners, and the drive wheel is supported on the motor housing by a drive bearing.

[0004] In the above structure, the cantilever is connected to the motor housing via fasteners, achieving a connection between the cantilever and the motor housing. However, during installation, the cantilever is fixedly mounted on the forklift. When the forklift motor is in use, it generates significant vibrations that are transmitted to the cantilever. Over time, this can cause the fasteners to loosen, affecting the stability of the forklift motor. Furthermore, to ensure a stable connection between the cantilever and the motor housing, multiple connectors are required. However, since the motor housing not only houses the cantilever but also the drive wheel, the installation positions of the drive wheel and the cantilever must be staggered during installation to prevent mutual interference. Consequently, this structure affects the installation efficiency of the cantilever and motor, as well as the stability of the forklift motor. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a mounting structure for a forklift motor. The technical problem to be solved by this utility model is: how to solve the problems of low installation efficiency and poor stability of existing forklift motors during use.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A mounting structure for a forklift motor, the forklift motor including a motor spindle, a stator, and a motor rotor fixed on the motor spindle, characterized in that the mounting structure includes a cantilever, the lower end of the cantilever being a mounting part, the mounting part having a through hole for placing the stator, and motor end caps provided at both the front and rear ends of the mounting part, the two ends of the motor spindle being rotatably connected to the corresponding motor end caps, the inner side of the two motor end caps abutting against the mounting part both having a protruding annular limiting ring, the inner side wall of the mounting part being abutted against the outer side wall of the limiting ring and the motor end caps being pressed onto the mounting part by fasteners.

[0008] By using the cantilever mounting section as the motor housing, the original motor housing is eliminated. Two motor end caps are directly installed at the front and rear ends of the mounting section, respectively, and then fixed to the mounting section. This achieves the installation of the forklift motor and the cantilever. To ensure the installation stability and efficiency between the cantilever and the forklift motor, a limiting ring is formed on the motor end cap. During installation, the limiting ring is first embedded into the mounting section and then fixed with fasteners. This provides circumferential positioning of the motor end cap, and the fasteners ensure the stability of the connection between the motor end cap and the mounting section. By directly using the cantilever mounting section as the motor housing, the installation and fixing of the cantilever and motor housing are eliminated. Instead, the connection between the forklift motor and the cantilever is achieved through the connection between the motor end cap and the cantilever mounting section, thereby improving the installation efficiency and the stability of the forklift motor.

[0009] In the forklift motor mounting structure described above, a ring-shaped reinforcing part is formed by radially protruding on the outer side wall of the middle part of the mounting section.

[0010] Since the upper end of the cantilever needs to be fixed to the existing forklift, the entire cantilever exerts an upward pulling force on the forklift motor. In order to ensure the strength of the middle part, a reinforcing part is added here to improve the structural strength of the part, facilitate the mounting of the forklift motor, and improve the installation stability of the forklift motor.

[0011] In the forklift motor mounting structure described above, the two motor end caps are positioned opposite each other and have multiple reinforcing ribs formed on the wall protrusions.

[0012] Since the two ends of the motor spindle are rotatably connected to the motor end cover, in order to improve the stability of the rotatable connection of the motor spindle, reinforcing ribs are added to the motor end cover to improve the structural strength of the motor end cover and the forklift motor.

[0013] In the above-described forklift motor mounting structure, a planetary gear set is connected to the rear end of the motor spindle. The planetary gear set has an output flange, and a rotating cover is fixedly connected to the output flange. A drive wheel is fixedly connected to the front end of the rotating cover, and the hub of the drive wheel is supported by a bearing on the outer wall of the mounting part.

[0014] The driving force of the motor spindle is transmitted to the output flange of the planetary gear set. The output flange transmits the force to the drive wheel through the rotating cover, thereby driving the drive wheel to rotate. In order to provide support for the drive wheel, a bearing can be used to support it between the mounting part and the drive wheel hub, which improves the stability of the drive wheel rotation. Furthermore, the cantilever is integrally formed with the motor housing, and there is sufficient space in the mounting part of the cantilever to provide for the installation of the drive wheel during installation, which makes the installation and positioning of the drive wheel more convenient and improves stability.

[0015] In the above-described forklift motor mounting structure, the front end of the bearing inner ring abuts against the rear end of the reinforcing part.

[0016] The reinforcement not only strengthens the cantilever but also acts as a limit, improving the stability of the forklift motor installation.

[0017] Compared with the prior art, the present invention has the following advantages: by forming a limiting ring on the motor end cover, the limiting ring can be embedded into the mounting part before being fixed by fasteners when the mounting part is installed with the motor end cover. This can provide circumferential positioning of the motor end cover, and the fasteners ensure the stability of the connection between the motor end cover and the mounting part. This improves the overall integration effect, as well as the installation efficiency and stability. Attached Figure Description

[0023] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0024] like Figure 1 and Figure 2 As shown, the mounting structure of this forklift motor includes a motor spindle 1, a stator 2, and a motor rotor 3 fixed on the motor spindle 1.

[0025] Specifically, such as Figure 1 and Figure 2As shown, this mounting structure includes a cantilever 4, the lower end of which is a mounting part 41. The mounting part 41 has a through hole 41a for placing the stator 2. The front and rear ends of the mounting part 41 are provided with motor end covers 5. The two ends of the motor spindle 1 are rotatably connected to the corresponding motor end covers 5. The inner side of the end of the two motor end covers 5 that abuts against the mounting part 41 protrudes to form an annular limiting ring 51. The inner side wall of the mounting part 41 is attached to the outer side wall of the limiting ring 51 and the motor end cover 5 is pressed onto the mounting part 41 by fasteners 6.

[0026] By using the mounting part 41 of the cantilever 4 as the motor housing, the original motor housing is eliminated. Two motor end covers 5 are directly installed at the front and rear ends of the mounting part 41, respectively, and the motor end covers 5 are fixedly connected to the mounting part 41, thus realizing the installation between the forklift motor and the cantilever 4. In order to ensure the installation stability and efficiency between the cantilever 4 and the forklift motor, a limiting ring 51 is formed on the motor end cover 5. When installing the mounting part 41 and the motor end cover 5, the limiting ring 51 can be embedded into the mounting part 41 first and then fixed by the fastener 6. This can provide circumferential positioning of the motor end cover 5. The fastener 6 ensures the stability of the connection between the motor end cover 5 and the mounting part 41. By directly using the mounting part 41 of the cantilever 4 as the motor housing, the installation and fixing of the cantilever 4 and the motor housing are eliminated. Instead, the connection between the forklift motor and the cantilever 4 is realized through the connection between the motor end cover 5 and the mounting part of the cantilever 4, thereby improving the installation efficiency and the stability of the forklift motor during use.

[0027] like Figure 2 and Figure 4 As shown, a ring-shaped reinforcing part 42 is formed on the outer wall of the middle part of the mounting part 41 along the radial direction, and multiple reinforcing ribs 52 are formed on the wall protrusions of the two motor end caps 5 facing each other.

[0028] like Figure 2 and Figure 3 As shown, a planetary gear set 7 is connected to the rear end of the motor spindle 1. The planetary gear set 7 has an output flange 71. A rotating cover 8 is fixedly connected to the output flange 71. A drive wheel 9 is fixedly connected to the front end of the rotating cover 8. The hub 91 of the drive wheel 9 is supported by a bearing 10 between it and the outer wall of the mounting part 41. The front end of the inner ring of the bearing 10 abuts against the rear end of the reinforcing part 42.

[0029] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
