Abstract
The utility model provides a super little rubbing crusher bearing dust keeper, includes the base, the base is installed on super little rubbing crusher's main shaft through the shaft hole that sets up, shaft hole top and bottom all be provided with the mounting groove, all install the skeleton oil blanket in the mounting groove, the base top surface is provided with the dust exhaust groove, dust exhaust groove one end with correspond the mounting groove and link to each other, the other end extends to base outside edge, be provided with annular bulge on the base bottom surface, annular bulge is coaxial with the shaft hole, bearing and gland are installed from bottom to top to the main shaft, the gland is located annular bulge. Super little rubbing crusher bearing dust keeper passes through the skeleton oil blanket in the mounting groove of upper portion, can block among super little rubbing crusher that slight dust enters into the bearing of main shaft downwards, avoids the dust to get into lubricating oil and glues its change thick, guarantees the lubricated effect of lubricating oil, improvement main shaft life, and the reduction maintenance cost, work, improvement production efficiency are stabilized for a long time to assurance equipment. Skeleton oil blanket in the mounting groove of lower part avoids lubricating oil to pollute the material in can preventing still in the bearing that lubricating oil permeates super little rubbing crusher, guarantees product quality.
Description
Technical field
This utility model relates to super micron mill technical field, specifically, is a kind of super micron mill bearing dustproof device。
Background technology
Super micron mill be utilize air separate, weight grind, shear form to realize the equipment of dryness material superfine comminution。When super micron mill is properly functioning, material is fine solid particle shape, operation enters bearing along main shaft, destroys oil lubrication effect, reduce bearing service life, it is a set of that super micron mill on average monthly just need to change bearing, improve maintenance cost, it is necessary to about 4 hours maintenance time is each, hygienic cleaning disinfecting time 2 hours, affect production equipment properly functioning, directly affect production efficiency and production cost。Having the device of compression air conservation actuating device at present, but need to be equipped with relevant corollary equipment, energy consumption is higher, is not suitable for the micronic dust protection of single device。
Utility model content
The deficiency that this utility model exists for above-mentioned prior art, it is proposed that a kind of super micron mill bearing dustproof device。
Super micron mill bearing dustproof device of the present utility model, including pedestal, described pedestal is arranged on the main shaft of super micron mill by the axis hole arranged, described axis hole top and bottom are both provided with mounting groove, it is fitted with outside framework oil seal in described mounting groove, described base top surface is provided with dust discharging grooves, described dust discharging grooves one end is connected with corresponding mounting groove, the other end extends to pedestal outer ledge, described base bottom surface is provided with annular projection, described annular projection is coaxial with axis hole, described main shaft is provided with bearing and gland from bottom to top, described gland is positioned at annular projection。
Preferably, described dust discharging grooves is positioned on the tangent line at mounting groove edge。
The beneficial effects of the utility model are: super micron mill bearing dustproof device is by the outside framework oil seal in the mounting groove of top, can stop that in super micron mill, fine solid particle is downwardly in the bearing of main shaft, avoid dust to enter lubricating oil to be become viscous, ensure the lubricant effect of lubricating oil, improve Main Shaft Service Life, reduce maintenance cost, it is ensured that equipment long-time stable works, improve production efficiency。Outside framework oil seal in the mounting groove of bottom still prevents lubricating oil in bearing and penetrates in super micron mill, it is to avoid lubricant pollution material, it is ensured that product quality。Upper and lower two outside framework oil seals form two-layer and seal, and improve its effect intercepting dust or lubricating oil further, enhance dust-proof effect and the effect of anti-oil seepage。
The annular projection arranged is anchored on the gland of bearing, makes whole dustproof construction stable connection, forms a step trough in pedestal bottom, it is possible to play certain sealing property, improves further and seals antiseep and dust-proof effect。The dust entered in pedestal groove installed above can be discharged by dust discharging grooves, will not continue downwards seepage, improves dust-proof effect。Dust discharging grooves tangential direction is arranged so that it is tangent with direction of rotation, improves the speed that dust is discharged。
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation one of this super micron mill bearing dustproof device；
Accompanying drawing 2 is the structural representation two of this super micron mill bearing dustproof device；
Accompanying drawing 3 is the structural representation three of this super micron mill bearing dustproof device。
Detailed description of the invention
In order to be able to further appreciate that structure of the present utility model, feature and other purpose, describing in detail as follows in conjunction with appended preferred embodiment, illustrated preferred embodiment is merely to illustrate the technical solution of the utility model non-limiting this utility model。
Detailed description of the invention of the present utility model is as follows:
Embodiment one:
If Fig. 1 is to, shown in 2, changing super micron mill bearing dustproof device and include pedestal 1, pedestal 1 is arranged on the main shaft 3 of super micron mill by the axis hole 2 arranged。
Axis hole 2 top and bottom are both provided with mounting groove 4, are fitted with outside framework oil seal 5 in mounting groove 4。
Pedestal 1 end face is provided with dust discharging grooves 6, and dust discharging grooves 6 one end is connected with corresponding mounting groove 4, and the other end extends to pedestal 1 outer ledge。
Being provided with annular projection 7 on pedestal 1 bottom surface, annular projection 7 is coaxial with axis hole 2, and main shaft 3 is provided with bearing 8 and gland 9 from bottom to top, and gland 9 is positioned at annular projection 7。
Material is above, and the dust that material produces after grinding falls from the top down, and the outside framework oil seal 5 being located at top intercepts, will not downwardly in bearing 8, it is to avoid pollute the lubricating oil in bearing 8。The dust fallen can enter in dust discharging grooves 6, and move laterally along dust discharging grooves 6 and discharge。Even if the outside framework oil seal of top 5 lost efficacy, in the mounting groove 4 of lower section, also have an outside framework oil seal 5 can play sealing function。
Annular projection 7 forms a lid, and lid installs on bearing 8 and gland 9, and annular projection 7 internal diameter is more than mounting groove 4 internal diameter, forms a step trough with certain sealing property, improves sealing effectiveness。Due to the stop of lower section outside framework oil seal 5, the lubricating oil in bearing 8 is without permeating up in super micron mill, it is to avoid lubricant pollution material。
Embodiment two:
Embodiment two is essentially identical with the structure of embodiment one composition, is distinctive in that:
Dust discharging grooves 6 is positioned on the tangent line at mounting groove 4 edge。Make the dust rotated along with main shaft be got rid of rapidly in dust discharging grooves 6, improve the speed that dust is discharged, it is ensured that the effect of dust seal。
