[0037] Configuration of cooling fan mounting structure

[0038] First, refer to Figure 1 to Figure 6 , the configuration of the mounting structure of the cooling fan according to the first embodiment will be described. figure 1 It is a front view of the attachment structure of the cooling fan of 1st Embodiment. figure 2 It is the anti-output side end view of the attachment structure of the cooling fan of 1st Embodiment. image 3 It is an enlarged view of main parts of the mounting structure of the cooling fan of the first embodiment.

[0039] Such as figure 1 with figure 2 As shown, the cooling fan installation structure of the first embodiment is used to install the cooling fan 20 on the servo motor 10 , and the cooling fan 20 is used to cool the servo motor 10 .

[0040] The servo motor 10 has a stator and a rotor (not shown) inside the housing 11 . An output-side bracket 12 is provided at the output-side end of the frame 11 . On the other hand, an anti-output side...

no. 2 approach

[0069] Next, refer to Figure 7 , the mounting structure of the cooling fan of the second embodiment will be described. Figure 7 It is an enlarged view of main parts of the mounting structure of the cooling fan of the second embodiment. In addition, in the second embodiment, the same structural members as those in the first embodiment are described using the same reference numerals.

[0070] Such as Figure 7 As shown, the cooling fan mounting structure of the second embodiment differs from the first embodiment in that no bottom plate is provided and that mounting bolts 70 are fixed with nuts 73 .

[0071] That is, the mounting structure of the cooling fan of the second embodiment does not have a bottom plate (refer to figure 1 , image 3 , Figure 4A with Figure 4B ). In addition, through-holes (not shown) for inserting the mounting bolts 70 are formed through the end plate 31 of the ventilation cover 30 on the side of the cooling fan 20 . In addition, in the coolin...

Abstract

A structure for attaching a cooling fan includes: a fan attachment plate interposed between a ventilation cover of a servomotor and the cooling fan and having a cut-out hole; and a tubular vibration-proof member supported by the cut-out hole of the fan attachment plate and fixed to the ventilation cover.

Description

[0001] Cross References to Related Applications [0002] This application claims the priority of Japanese Patent Application No. 2014-081407 filed with the Japan Patent Office on April 10, 2014, and therefore the entire content of said Japanese Patent Application is incorporated herein by reference. technical field [0003] The invention relates to a cooling fan installation structure. Background technique [0004] A servo motor is known as a motor capable of controlling position, speed, and the like using a servo mechanism. Servo motors are used, for example, to drive load devices such as gear reducers and hydraulic pumps. When the temperature of the coil increases due to the driving of the servo motor, the performance of the servo motor decreases. [0005] Therefore, a cooling fan is provided in the servo motor to suppress the temperature rise of the coil. In the past, the cooling fan was directly fixed on the casing or bracket of the servo motor, or fixed on the casing...
