Abstract

The utility model discloses a special-purpose locating and assembling tool for a bearing of a high-speed centrifuge, comprising a base, a second boss which is used for locating a bearing outer ring and arranged on the base, and a first boss which is used for locating a bearing inner race and arranged on the base. The first boss and the second boss are a raised structure which is arranged along the peripheral direction of the base and extends along the axial direction of the base; wherein the first boss is appropriately thicker than the second boss. The thickness of the first boss is larger than that of the second boss by 0.1 to 0.15 mm. The inner race and the outer ring of the bearing are located through the arrangement of the two raised structures to prevent the inner race and the outer ring of the bearing from relative displacement, which guarantees normal and stable working of the bearing after assembling the inner race and the outer ring into the bearing, thereby greatly improving the production efficiency and reducing the maintenance cost.

Description

The special-purpose location of the bearing of supercentrifuge assembly tool

Technical field

The utility model relates to the special-purpose location of a kind of bearing assembly tool, relates in particular to a kind of special-purpose location of bearing assembly tool that is used for the supercentrifuge of granulated wool production line.

Background technology

As shown in Figure 1, in the production and processing of granulated wool, the axle of supercentrifuge supports rotation by bearing 5 and bearing 6.In use, need earlier axle sleeve to be gone in bearing 5 and the bearing 6.Yet in dress axle process, bearing 5 is not ad hoc located at present, only the bossing of the outer end cap 9 by bearing housing positions the outer ring 7 of bearing 5, and inner ring 8 does not obtain the location.Though but this mode rigid bearing 5 in dress axle process, can not move bearing 5.Yet be pressed into the static pressure that is 30MP to the maximum of axle,, all bear on the ball and retainer of bearing 5 by the inner ring 8 of bearing 5.As shown in Figure 2, therefore, bearing 5 had born the power that surpasses rated static load before not having running, and relative displacement has taken place for its outer ring 7 and inner ring 8, and ball and retainer are damaged.Therefore firm phenomenon a locking of turning round often appears.

The utility model content

The technical problems to be solved in the utility model provides a kind of inner ring and outer ring generation relative displacement of avoiding bearing in dress axle process, causes the special-purpose location of the bearing assembly tool of the supercentrifuge of damage of bearings.

For solving the problems of the technologies described above, assembly tool is located in the bearing special use of supercentrifuge of the present utility model, and comprising: base, base are provided with second protuberance that is used for the location bearing outer ring, also are provided with first protuberance that is used for the location bearing inner ring on base.

Further, first protuberance and second protuberance are along the axially extended bulge-structure along base that is provided with on the circumferencial direction of base.

Further, first protuberance suitably is thicker than second protuberance.

Further, the thickness of first protuberance is than the big 0.1～0.15mm of thickness of second protuberance.

By two bulge-structures are set the inner ring and the outer ring of bearing positioned respectively, thereby make the inner ring of bearing and outer ring relative displacement can not take place, guaranteed behind the axle of packing into, the normal steady operation of bearing, thereby improved production efficiency greatly, reduced maintenance cost.

The specific embodiment

As shown in Figure 3 and Figure 4, the bearing of supercentrifuge of the present utility model location assembly tool comprises: base 1, on base 1, offer a passage 2, and this passage 2 is used at an axle 10 that passed through to be packed in 10 o'clock of packing into.On base 1, also be provided with first protuberance 3 and second protuberance 4 along the circumferencial direction of base 1, this first protuberance 3 and second protuberance 4 are the axially extended raised structures along base 1.Wherein first protuberance 3 is used in the process of axle 10 of packing into, and inner ring 8, the second protuberances 4 of location bearing 5 are used for the outer ring 7 of location bearing 5.

As shown in Figure 5, the direction of center arrow is being pressed into axle 10 in the process of bearing 5 for the direction that is pressed into of axle 10, and the static pressure that is pressed into that acts on the axle 10 will affact on the inner ring 8 of bearing 5 by axle 10.Make the relative outer rings 7 of inner ring 8 of bearing 5 produce the trend that relatively moves, eliminated this trend for the location of the inner ring 8 of bearing 5 by first protuberance 3, thereby, reach under the prerequisite of not damaging bearing 5, axle 10 is packed in bearing 5 and the bearing 6 safely.

As shown in Figure 6, the occupation mode of the special-purpose location of the bearing of supercentrifuge of the present utility model assembly tool is as follows: before the axle 10 of packing into, the outer end cap 9 of bearing housing is not installed.Earlier the special-purpose location of the bearing of supercentrifuge of the present utility model assembly tool is inserted in the bearing housing 14, first protuberance 3 contacts with outer ring 7 with the inner ring 8 of bearing 5 respectively well with second protuberance 4; Then the bearing special-purpose location assembly tool of bearing housing 14 with supercentrifuge of the present utility model together is put on the tooling platform 13 of forcing press 12, the baseplane of the base 1 of the special-purpose location of the bearing of supercentrifuge of the present utility model assembly tool is close on the baffle plate 11 of tooling platform 13; At this moment, forcing press 12 begins to be pressed into axle 10.After axle 10 is pressed into, take off the special-purpose location of the bearing assembly tool of supercentrifuge of the present utility model, the bearing housing 14 of again outer end cap 9 of bearing housing being packed into.

By first protuberance 3 and the inner ring 8 of 4 pairs of bearings 5 of second protuberance and the location of outer ring 7, guaranteed that the inner ring 8 of bearing and outer ring 7 can relative displacement not take place vertically, have guaranteed that behind the axle of packing into, bearing 5 can operate as normal in dress axle process.Thereby avoided the frequent generation of seize accident.

Moreover, the thickness of first protuberance 3 is than the big 0.1～0.15mm of thickness of second protuberance 4, first protuberance 3 is fully contacted with the inner ring 8 of bearing 5, and the axial static pressure that produces when helping overcoming the dress axle is more eliminated in the frock process damage to bearing 5.

As shown in Figure 7, after adopting the assembly tool that is used for location bearing of the present utility model, bearing 5 is not subjected to any damage, thereby has improved production efficiency greatly, has saved maintenance cost.
