3, by arrange woodruff key be prevented from grinding wheel stand rotate in machine shaft generation relative sliding。
4, by arranging jump ring, it is possible to prevent grinding wheel stand from coming off in the running。
Accompanying drawing explanation
It is described in detail below in conjunction with the drawings and specific embodiments this utility model:
Fig. 1 is the structural representation of a kind of grinding head motor axle head waterproof construction of the present utility model。
The axial sectional view of protecgulum of the present utility model during Fig. 2。
Detailed description of the invention
A kind of grinding head motor axle head waterproof construction of the present utility model is as shown in Figure 1, it is identical with prior art (CN204179801U) is, the parts such as the grinding wheel stand 2, protecgulum 3 and the locking nut 4 being arranged in grinding wheel stand 2, pad 5, bearing 6, the internal bearing cover 7 that equally also include machine shaft 1, are sequentially arranged at machine shaft 1 from axle head, there is between the end face that grinding wheel stand 2 is relative with protecgulum 3 anti-water space, between protecgulum 3 front end and machine shaft 1, be provided with the first outside framework oil seal 8。Unlike the prior art, the second outside framework oil seal 9 it is additionally provided with between protecgulum 3 front end of the present utility model and grinding wheel stand 2 rear end, anti-water space is divided into inner segment gap and outer intersegmental gap by the second outside framework oil seal 9, inner segment gap is radially followed successively by the first vertical gap 10, the vertical gap 12 of horizontal clearance 11, second from inside to outside, outer intersegmental clearance diameter is to being followed successively by the 3rd vertical gap 13, gap, slope 14 and vertical seam fit clearance 15 from inside to outside, and bottom, gap, slope 14 is positioned at grinding wheel stand 2 side, top is positioned at protecgulum 3 side。
Seeing Fig. 2, the first described outside framework oil seal 8 and the second outside framework oil seal 9 are respectively arranged on protecgulum 3 in the first, second reinforced seal ring recess 16,17 offered。The external diameter of the second reinforced seal ring recess 17 is 70mm。
As an embodiment, adopt the Morse's taper of 1:10 to coordinate between described machine shaft 1 and grinding wheel stand 2, hot cover process can be cancelled, saved production cost, reduce dismounting difficulty, it is simple to change and maintenance, reduce after cost。
As an embodiment, between described machine shaft 1 and grinding wheel stand 2, also it is embedded with woodruff key 18, it is possible to prevent grinding wheel stand 2 from machine shaft 1, relative sliding occurring when rotating。
As an embodiment, described machine shaft 1 is provided with draw-in groove, is located at the jump ring 19 in order to fixed emery wheel seat 2 in draw-in groove, it is possible to prevent grinding wheel stand 2 from coming off in the running。
The waterproof principle of grinding head motor axle head waterproof construction of the present utility model is as follows:
When whole grinding head motor axle head is operated in hot and humid environment; to its barrier propterty; requiring all there is a good protective when static or operating, the parts such as protection locking nut 4, pad 5, bearing 6, internal bearing cover 7 are not corroded by water, fog。When grinding glass, simultaneously with water column spraying cooling, spray position is positioned at the end of grinding wheel stand 2, and the hydraulic pressure of spray is higher, and splash current out, it is easy to enters components interior, parts causes corrosion, and ultimately results in parts damages。
Therefore, this utility model is when operating, and machine shaft 1, woodruff key 18, jump ring 19 and grinding wheel stand 2 are one and rotate entirety, are high speed rotating, when water cool water shower is when the upper surface portion of grinding wheel stand 2, are thrown away by huge centrifugal force。The anti-water space that the water that part is splashed can pass through between grinding wheel stand 2 and protecgulum 3 enters, but can be blocked in outside by first and second outside framework oil seal 8,9, and is thrown away by the grinding wheel stand 2 of high speed rotating。
During grinding, the high-temperature heating cooling water of generation so that it is the fog of generation, also can by the two seals assemblies block of first and second outside framework oil seal 8,9 composition in outside。The rotatable parts being made up of machine shaft 1, locking nut 4, pad 5, bearing 6, internal bearing cover 7, can ensure that the situation in load runs up, machine shaft 1, grinding wheel stand 2 are collected together before and after not havinging, and destroy the sealing effectiveness of first and second outside framework oil seal 8,9。
In time shutting down, the cooling water of spray continues to work。At this moment the seal operation waiting whole proof mechanism of water is mainly all completed by first and second outside framework oil seal 8,9, and cooling water is entered by outer intersegmental clearance flow in the second reinforced seal ring recess 17 of protecgulum 3, is blocked in outside by the second outside framework oil seal 9, walks further through outer intersegmental clearance flow。If the moisture not flowed away penetrates in the first reinforced seal ring recess 16 of protecgulum 3, outside will be blocked in by the first outside framework oil seal 8, and enter and obtain water in the first reinforced seal ring recess 16, there is no pressure, so it is internal to enter protecgulum 3 again through the first outside framework oil seal 8。
In sum, adopt a kind of grinding head motor axle head waterproof construction of the present utility model, can jointly stop the erosion to protecgulum 3 internal part of external water, dust, fog by arranging two groups of skeleton oil seals, then with waterproof matched in clearance, to realize more efficiently waterproof effect。
But, those of ordinary skill in the art will be appreciated that, above embodiments is intended merely to explanation this utility model, and it is not used as to restriction of the present utility model, as long as in spirit of the present utility model, the change of embodiment described above, modification all will be dropped in Claims scope of the present utility model。
