Abstract
The utility model relates to an improved structure of a shock resistant motor fan housing. The structure comprises a motor base, an end cover and a fan housing fixed with the end cover. The structure is characterized in that the periphery of a motor base end face is provided with a plurality of air holes, the end cover is provided with air holes communicated with the motor base air holes, two end faces of the end cover are provided with front edges. An end face where the motor base is cooperated and installed with the end cover is provided with a front edge. The motor base and the end cover are assembled through the front edge in a cooperating manner. The end face where the fan housing is cooperated with the end cover is provided with the front edge. The fan housing and the end cover are cooperated and installed through the front edge. The periphery of the fan housing is provided with air holes communicated with the air holes on the end cover and the motor base. The structure is advantaged in that cooling air can blow to the surface of the motor base through the air holes on the motor base, the end cover, and the fan housing, thereby achieving effective heat radiation objective. The motor base, the end cover, and the fan housing are cooperated and installed through the front edges, and main force bearing points of the fan housing which is in a vibrating state can be transferred to the end cover front edge from fastening bolts, so that firm and reliable installation of the fan housing is ensured, durability is improved, life of the motor is prolonged, and potential safety hazard is prevented.
Description
Technical field
The utility model belongs to motor manufacture technology field, particularly relates to a kind of resistance to motor fan housing that shakes and improves structure.
Background technology
Vibrohammer threephase asynchronous is building trade and the supporting motor of basic engineering construction vibrohammer, can be widely used in the motorized motions of the various foundation construction engineering vibrohammers used such as bridge, harbour, tunnel and river levee.At present, traditional vibrohammer with threephase asynchronous machine fan housing structure is: support and end cap cylindrical weld several lugs and be placed on support in order to installation end, the path that between lug, space is cooling-air, fan housing without cooperation, is to be only attached on end cap to be bolted with end cap support again.The fan housing of above-mentioned motor exists following not enough: the weight of fan housing all puts on bolt, under vibration at high speed state, thereby is easy to make bolt looseness to cause bolt falling, in serious situation bolt can be sheared disconnected, the peril that causes motor fan housing to come off; More seriously end cap is separated from support, causes electric machine chamber-sweeping motor damage then, and then has potential safety hazard.
Summary of the invention
The utility model provides a kind of resistance to motor fan housing that shakes simple in structure, that effectively improve motor safety reliability and can improve motor radiating performance to improve structure for solving the technical problem existing in known technology.
The technical scheme that the utility model is taked for the technical problem existing in solution known technology is:
The resistance to motor fan housing that shakes improves structure, comprise support, end cap and with the fixing fan housing of end cap, on described support end face periphery, be shaped with multiple ventilation holes, on described end cap periphery, be shaped with the ventilation hole communicating with support ventilation hole, in described end cap both ends of the surface, be all shaped with seam, described support coordinate with end cap install an end face on be shaped with seam, described support and end cap are equipped with by seam; On the end face that described fan housing coordinates with end cap, be shaped with seam, described fan housing coordinates installation with end cap by seam, is shaped with the ventilation hole communicating with end cap and support ventilation hole on described fan housing periphery.
The utility model can also adopt following technical scheme:
On described support end face periphery, be shaped with 20-30 ventilation hole.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, can make cooling-air brush support surface by the ventilation hole on support, end cap, fan housing, reach effective heat radiation object; Support seam and end cap seam are equipped, fan housing coordinates installation by seam with end cap seam, the main stress point of fan housing under vibrational state can be transferred on end cap seam by construction bolt like this, not only can guarantee that fan housing is installed solid and reliable, improve durability, but also can extend life-span of motor, avoid occurring potential safety hazard.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is fan housing structure schematic diagram of the present utility model.
In figure: 1, support; 2, end cap; 3, fan housing; 4, ventilation hole; 5, fastening bolt.
Embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Be exemplary below by the embodiment being described with reference to the drawings, only for explaining the present invention, and can not be interpreted as limitation of the present invention.
Refer to Fig. 1 and Fig. 2, the resistance to motor fan housing that shakes improves structure, comprise support 1, end cap 2 and with the fixing fan housing 3 of end cap, on described support end face periphery, be shaped with multiple ventilation holes 4, on described end cap, be shaped with the ventilation hole 4 communicating with support ventilation hole.In described end cap both ends of the surface, be all shaped with installation seam, described support coordinate with end cap install an end face on be shaped with seam, described support and end cap are equipped with by seam; On the end face that described fan housing coordinates with end cap, be shaped with seam, described fan housing coordinates installation with end cap by seam, and fastening by fastening bolt 5 and end cap.On described fan housing periphery, be shaped with the ventilation hole 4 communicating with end cap and support ventilation hole.
In the present embodiment, on described support end face periphery, be shaped with 20-30 ventilation hole 4, can be big or small and different according to rating of machine.
The surface that this fan housing can make cooling-air brush support by the ventilation hole 4 on support 1, end cap 2 and fan housing 3, reaches significant heat radiation object.Because fan housing 3 adopts seam to coordinate mounting means with end cap 2, the main stress point of fan housing under vibrational state can be transferred on end cap 2 seams by fastening bolt, be made so main stress point on end cap, and then guarantee the reliability that fan housing is installed, improve durability, extend the life-span of motor.
Claims (2)
1. the resistance to motor fan housing that shakes improves structure, comprise support, end cap and with the fixing fan housing of end cap, it is characterized in that: on described support end face periphery, be shaped with multiple ventilation holes, on described end cap periphery, be shaped with the ventilation hole communicating with support ventilation hole, in described end cap both ends of the surface, be all shaped with seam, described support coordinate with end cap install an end face on be shaped with seam, described support and end cap are equipped with by seam; On the end face that described fan housing coordinates with end cap, be shaped with seam, described fan housing coordinates installation with end cap by seam, is shaped with the ventilation hole communicating with end cap and support ventilation hole on described fan housing periphery.
