Abstract
The utility model discloses a quick-insert type motor rotor bearing dismounting tool, which is arranged between a rotor and a bearing. The dismounting tool is a round clamping plate. The external diameter D2 of the round clamping plate is larger than the external diameter D3 of the rotor. An opening groove is arranged on the dismounting tool. The width L1 of the opening groove is larger than the diameter D1 of a rotor shaft between the rotor and the bearing. The thickness L2 of the opening groove is smaller than the distance L3 between the rotor and the bearing. The tool can make the bearing rapidly dismounted. Meanwhile, the bearing is integrally drawn out. Therefore, the bearing is prevented from being damaged.
Description
Technical field
The utility model relates to a kind of bearing extractor, and more particularly, the utility model relates to a kind of motor rotor bearing extracting tool.
Background technology
The motor rotor shaft two ends are equipped with bearing, and under normal circumstances, bearing and armature spindle adopt tight fit.In the time of bearing need to being unloaded, the pulling claw of bearing puller is stretched between rotor and bearing, after holding bearing outer ring with the pulling claw of bearing puller, bearing is pulled out.When using this dismounting mode to dismantle, exist certain defective, the one, bearing outside diameter is less, and the space between rotor and bearing is less, and the pulling claw end of bearing puller is generally larger, the pulling claw of bearing puller is not easy to stretch between rotor and bearing; The 2nd, after holding bearing outer ring with the pulling claw of bearing puller, bearing is pulled out, easily damage bearing.
The utility model content
The utility model provides a kind of simple in structure for the deficiencies in the prior art, can dismantle quickly bearing, and can avoid the rapid plug-in motor rotor bearing extracting tool of damage of bearings.
The utility model is achieved through the following technical solutions technical goal.
Rapid plug-in motor rotor bearing extracting tool is arranged between rotor and bearing, and its improvements are: described extracting tool is circular clamp, and its D outer diameter 2 is greater than rotor diameter D3; Be provided with an open slot on extracting tool; The width L1 of described open slot is greater than armature spindle diameter D1 between rotor and bearing, and thickness L2 is less than the spacing L3 between rotor and bearing.
Further improve as the utility model: extracting tool D outer diameter 2 is than the large at least 10mm of rotor diameter D3; The width L1 of described extracting tool open slot is than the large 1～4mm of armature spindle diameter D1 between rotor and bearing; The thickness L2 of described extracting tool open slot is than the little 1～5mm of the spacing L3 between rotor and bearing.
The utility model compared with prior art has following good effect:
1. circular clamp, simple in structure.
When 2, using, the utility model can insert between rotor and bearing quickly, because extracting tool is circular clamp, its external diameter is greater than rotor diameter, the utility model exceeds rotor, and the pulling claw of bearing puller is held edge of the present utility model at an easy rate, and bearing is pulled out.Whole unloading process is very quick, and owing to being that whole bearing is pulled out together, has avoided the damage of bearing.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the left view in Fig. 1.
Fig. 3 is that the utility model inserts the schematic diagram between rotor and bearing.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and in conjunction with the embodiments for the below.
Rapid plug-in motor rotor bearing extracting tool shown in the drawings is arranged between rotor 3 and bearing 1, and extracting tool 2 is circular clamp, and its extracting tool 2 D outer diameter 2 are than the rotor 3 large at least 10mm of D outer diameter 3; In the present embodiment, extracting tool 2 D outer diameter 2 are than the rotor 3 large at least 30mm of D outer diameter 3; Be provided with an open slot 4 on extracting tool 2; The width L1 of open slot 4 is than the large 1～4mm of armature spindle diameter D1 between rotor 3 and bearing 1, and in the present embodiment, the width L1 of open slot 4 is than the large 2mm of armature spindle diameter D1 between rotor 3 and bearing 1; The thickness L2 of extracting tool 2 open slots 4 is than the little 1～5mm of spacing L3 between rotor 3 and bearing 1, and in the present embodiment, the thickness L2 of extracting tool 2 open slots 4 is than the little 3mm of spacing L3 between rotor 3 and bearing 1.
During use, the utility model can insert between rotor 3 and bearing 1 quickly, because extracting tool 2 is circular clamp, its external diameter is greater than rotor diameter, the utility model exceeds rotor 3, and the pulling claw of bearing puller is held edge of the present utility model at an easy rate, and bearing 1 is pulled out.Whole unloading process is very quick, and owing to being that whole bearing 1 is pulled out together, has avoided the damage of bearing 1.
