Abstract
The invention relates to a fixing device of a fan cover. The fixing device of the fan cover comprises a box body, wherein an end cover is arranged on the outer side of the box body; a rotary shaft is arranged in the box body; one end part, exposed outside the box body, of the rotary shaft is connected with a plurality of fan blades; the fan blades run along with the rotation of the rotary shaft; the fan cover is arranged on the outer sides of the blades, and is fixedly connected onto a fixing plate arranged on the corresponding position of the end cover; the fixing plate is fixedly connected with the end cover through a plurality of cushion blocks; a gap is reserved between the fixing plate and the end cover; a plurality of through holes are circumferentially and densely formed in a fixing plate body; ventilation holes are formed in the fan cover. The fixing plate on the end cover and the fan cover are fixedly connected, so that the fan cover can be arranged on the box body safely, and is convenient to disassemble and assemble; the through holes and the ventilation holes are formed, so that the whole device can radiate heat in time when being operated.
Description
Technical field
The present invention relates to a kind of fixing device of fan guard, be specifically related to a kind of fan guard fixing device of speed reducer.
Background technique
A large amount of heats can be produced in the operation process of speed reducer, and generally all can the fan guard of in addition safety outside when using fan for cooling, security incident can not be caused by getting to when ensureing operative, and fan guard is generally all fixed on casing, not only processed bother but also outward appearance ugly, and in use because of loftier on casing, easily bring inconvenience.
Summary of the invention
The object of the present invention is to provide a kind of fixing device of fan guard, by electric motor end cap place mounting plate, fixed plate and fan guard are fixed, structure is simple and Security is high.
For achieving the above object, the invention provides a kind of fixing device of fan guard, comprise casing, end cap is provided with outside described casing, inside is provided with rotating shaft, the end that described rotating shaft is exposed at outside casing connects several fan blade, and operate with axis of rotation, at described blade outboard, one fan guard is installed, described fan guard is fixedly connected on the fixed plate that described end cap corresponding position is provided with, described fixed plate is fixedly connected with end cap by several cushion blocks, and and leave space between end cap; On described fixed plate body, circumference is densely covered with multiple through hole, and described fan guard is provided with vent hole.To be connected by the fixed plate on end cap and fan guard are fixing, fan guard must be arranged on casing safely, and easy accessibility; The setting of through hole and vent hole makes whole device can dispel the heat in time in the running.
Further improvement of the present invention is: the vent hole on described fan guard is distributed on the bottom surface of fan guard body, corresponding with the lead to the hole site on fixed plate.Through hole is corresponding with vent hole, makes gas permeability reach optimum efficiency.
The invention has the beneficial effects as follows: on the end cap of casing, set up fixed plate, while enabling fan guard fixing, assurance device dispels the heat in time again, and the vent hole of correspondence and through hole effectively can carry out air permeable and heat exhausting.

Embodiment
In order to deepen the understanding of the present invention, below in conjunction with drawings and Examples, the present invention is described in further detail.
By reference to the accompanying drawings 1 with accompanying drawing 2, the present invention proposes a kind of fixing device of fan guard, comprise casing 1, end cap 2 is provided with outside described casing 1, inside is provided with rotating shaft 10, described rotating shaft 10 end be exposed at outside casing 1 connects several fan blade 9, and rotate with rotating shaft 10 and operate, one fan guard 5 is installed outside described blade 9, described fan guard 5 is fixedly connected on the fixed plate 4 that described end cap 2 corresponding position is provided with, by cooperatively interacting, by fan guard 5 edge together with fixed plate 4 compact siro spinning technology of stud 7 and nut 8.Described fixed plate 4 is fixedly connected with end cap 2 by several cushion blocks 3, and see accompanying drawing 3, fixed plate 4 is circular, and inner side annulus is provided with tapped hole, by bolt 6 through tapped hole, makes it be fixed on cushion block 3, and and leaves space between end cap 2.By reference to the accompanying drawings 4 and accompanying drawing 5, on described fixed plate 4 body, circumference is densely covered with multiple through hole 12, and described fan guard 5 is provided with vent hole 11.Vent hole 11 on described fan guard 5 is distributed on the bottom surface of fan guard 5 body, corresponding with the lead to the hole site on fixed plate 4.
To be connected with fan guard 5 is fixing by the fixed plate 4 on end cap 2, fan guard 5 must be arranged on casing 1 safely, and easy accessibility; Through hole 12 is corresponding with vent hole 11, and whole device can dispel the heat in the running in time.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure transformation utilizing specification of the present invention and accompanying drawing content to do; such as fixed plate is the rectangular thin plate etc. of middle with hole; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
