Abstract

The utility model provides a bearing where a pull-to-detach portion (1) is arranged. The bearing is simple in structure and is easy to detach by cooperating with appliances.

Description

Bearing
Technical field
The utility model relates to engineering part, relates in particular to a kind of bearing.
Background technique
The dismounting of bearing is generally decided according to the fiting property of structure, size and the bearing part of bearing.The method for dismounting of bearing mainly contains: (1) hammering method.Percussion power generally is added in bearing inner race, and this method is simple, does not need special tool, but damage bearing easily, when bearing is positioned at the tip of the axis, use copper rod or other softer metals to prop up axle head less than bearing bore diameter, the bearing bottom adds cushion block, knocks gently with hand hammer, can pull down.(2) pull out method.Adopt special use to draw tool, during dismounting, as long as rotatable handle, bearing will slowly be pulled out.During the dismounting bearing outer ring, draw tool bipod bent angle outwards to open; Dismounting is during bearing inner race, draws the tool bipod should be inside, is stuck on the bearing inner race end face.(3) pushing method.Push bearing with press machine, stable working is reliable, does not damage machine and bearing.Press machine has manual pushing, mechanical type or hydraulic press machine pushing.(4) heat is torn method open.Be used to dismantle friction tight bearing.The machine oil that will be heated to earlier about 100 ℃ is cast on the bearing to be torn open with oil can, treat the race ring expanded by heating after, promptly availablely draw tool that bearing is pulled out.
Said method is wasted time and energy in the unloading process of bearing, damages bearing simultaneously easily.Sometimes also need to increase the size of bearing, the weight of increase bearing.
The model utility content
The utility model aims to provide a kind of bearing, to solve the size that wastes time and energy, needs to increase bearing when the prior art middle (center) bearing is dismantled, the problem that increases the weight of bearing.
To achieve these goals, the utility model provides a kind of bearing, has the portion of unloading of pulling out on the bearing.
Further, bearing of the present utility model comprises outer shroud and interior ring, pulls out the portion of unloading and is arranged on the interior ring.
Further, pull out the portion of unloading and comprise: annular protrusion, extend vertically from least one end of interior ring; Pull out and unload groove, be arranged on the annular protrusion.
Further, pull out that to unload groove be the annular groove that is arranged on the annular protrusion.
Further, the opening of annular groove is towards the outer shroud direction.
Further, bearing is a rolling bearing.
Bearing of the present utility model has the portion of unloading of pulling out, and can carry out the dismounting of bearing by instrument fast with pulling out cooperating of the portion of unloading, and can not cause damage to bearing or other parts simultaneously in unloading process.And have advantages such as simple in structure, in light weight.
Description of drawings
The Figure of description that constitutes the application's a part is used to provide further understanding of the present utility model, and illustrative examples of the present utility model and explanation thereof are used to explain the utility model, do not constitute improper qualification of the present utility model.In the accompanying drawings:
Fig. 1 has schematically shown the sectional view according to the embodiment of bearing of the present utility model.
Embodiment
Need to prove that under the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.Describe the utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
Fig. 1 shows the preferred embodiment of bearing of the present utility model, and the bearing of present embodiment is a rolling bearing, has the portion of unloading 1 of pulling out on this bearing.Can carry out the dismounting of bearing by instrument fast with pulling out cooperating of the portion of unloading 1, in unloading process, can not cause damage simultaneously bearing or other parts.And have advantages such as simple in structure, in light weight.
As shown in Figure 1, preferably, the bearing of present embodiment comprises outer shroud 2 and interior ring 3, pulls out the portion of unloading 1 and is arranged on the interior ring 3.In the process of bearing removal, the instrument drag hook of utilization hooks the interior ring 3 of bearing, and bearing is extracted.Usually the cooperation of bearing inner ring and axle is an interference fit, pulls out the portion of unloading 1 and is arranged on the interior ring 3, can not damage bearing during the dismounting bearing.
The embodiment of pulling out the portion of unloading 1 has multiple, with the structure of instrument certain relation is arranged also.Wherein a kind of mode of execution pulls out the portion of unloading 1 and comprises as shown in Figure 1: annular protrusion 11, extend vertically from least one end of interior ring 3; Pull out and unload groove 12, be arranged on the annular protrusion 11, this is simple in structure, and processing easily.
Preferably, as shown in Figure 1, pull out and unload groove 12 for being arranged on the annular groove on the annular protrusion 11, the opening of this annular groove is towards outer shroud 2 directions.When tool using carries out bearing removal, make the center hole of the screw mandrel aiming axis of instrument, should be noted that simultaneously and avoid deflection, should also be noted that the stressing conditions of drag hook and bearing.Opening direction helps and the cooperating of instrument towards the circular groove structure of outer shroud 2, helps avoid deflection, thereby bearing is caused damage.
As can be seen from the above description, the utility model the above embodiments have realized following technique effect:
Bearing of the present utility model is particularly useful for Helicopter Transmission System, pulls out the portion of unloading by being provided with on bearing, thereby has simplified the detaching structure design, makes more compact structure, and has effectively alleviated structure weight.Bearing of the present utility model has passed through experimental verification, carries out the dismounting of bearing very easily, has significantly reduced the time of bearing removal, has effectively improved working efficiency.
The above is a preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
