Abstract
The utility model discloses a kind of motor test gear hot jacket positioner, including sample block, positioning screw, locating rack, lock nut and fixing bolt, described locating rack is inverted U, described positioning screw is threaded through front end from locating rack rear end, described sample block is arranged on positioning screw front end, described lock nut is arranged on locating rack rear end, and described fixing bolt is screwed into inner side in locating rack rear end from outside.The beneficial effects of the utility model are: different types of motor, select the sample block of different-thickness, thus ensure that the test gear amount of being inserted in of same type motor meets technological requirement, and ensure that the amount of being inserted in of each type motor test gear is basically identical, ensure that the reliability of test gear set, thus stopped to test the phenomenon being difficult to remove after gear occurs slipping and falling off or having tested in process of the test and machine shaft and test gear destruction or the phenomenon scrapped.
Description
Technical field
This utility model relates to technical field of motors, particularly a kind of motor test gear hot jacket positioner.
Background technology
After existing direct current/pulse current electric motor test gear is heated to set point of temperature, direct hot jacket, in the rotating shaft of motor, does not has
Take other restriction or location measure with the amount of being inserted in of Control experiment gear.
Through practice, existing motor test gear hot jacket mode can cause the amount of the being inserted in difference of every motor test gear relatively
Greatly.When the amount of being inserted in is the least, test gear can slip and fall off in motor testing process, causes machine shaft and test gear to damage
Wound, it is impossible to complete test, the most also can cause machine shaft and test scrapping of gear；When the amount of being inserted in is the biggest, test gear
Dismounting the most highly difficult.
Therefore, it is highly desirable to existing motor test gear hot jacket mode is improved.
Utility model content
Goal of the invention of the present utility model is: for the problem of above-mentioned existence, according to motor and the structure of test gear
Feature, it is provided that a kind of motor test gear hot jacket positioner.
The technical solution adopted in the utility model is such that
A kind of motor test gear hot jacket positioner, including sample block, positioning screw, locating rack, lock nut and fixing
Bolt, described locating rack is inverted U, and described positioning screw is threaded through front end from locating rack rear end, and described sample block is arranged on fixed
Position screw front end, described lock nut is arranged on locating rack rear end, described fixing bolt in locating rack rear end in outside is screwed into
Side.
As preferably, described locating rack rear end is higher than front end, and described fixing bolt is arranged on the rear end of locating rack.Locating rack
This preferred constructive form, can on the premise of reducing weight as far as possible, can guarantee that again bolt can be screwed into inner side
Test gear face is fixed.Locating rack can also use other positioning forms, e.g., between locating rack two end side panels away from
From adjustable, directly by side plate, test gear be clamped, and bolt need not be fixed, but the amount of being inserted in of this mode is consistent
Property is relatively poor.
As preferably, described lock nut has two, is arranged at locating rack rear end.The effect of two lock nuts is set
It is, prevents lock nut from unclamping and have influence on the amount of being inserted in of test gear.
In sum, owing to have employed technique scheme, the beneficial effects of the utility model are:
1, different types of motor, selects the sample block of different-thickness, thus ensures the test geared sleeve of same type motor
Enter amount and meet technological requirement, and ensure that the amount of being inserted in of each type motor test gear is basically identical, it is ensured that test gear
The reliability of suit, thus stopped to be difficult to dismounting after test gear occurs slipping and falling off or having tested in process of the test
Phenomenon and machine shaft and test gear destruction or the phenomenon scrapped；
2, directly this positioner is placed on and then tightens fixing bolt on test gear and got final product back-to-back test gear
Pinching action, simple to operate quickly.
Accompanying drawing explanation
Fig. 1 is use view of the present utility model.
Labelling in figure: 1 is sample block, 2 is positioning screw, and 3 is locating rack, and 4 is locking nut, and 5 is fixing bolt, and 6 is electricity
Machine seal ring, 7 is test gear, and 8 is machine shaft.
Detailed description of the invention
Below in conjunction with the accompanying drawings, this utility model is described in detail.
Embodiment:
As it is shown in figure 1, a kind of motor test gear hot jacket positioner, including sample block 1, positioning screw 2, locating rack 3, lock
Determining nut 4 and fixing bolt 5, described locating rack 3 is inverted U, and described positioning screw 2 is threaded through front end from locating rack 3 rear end,
Described sample block 1 is arranged on positioning screw 2 front end, and described lock nut 4 is arranged on locating rack 3 rear end, and described fixing bolt 5 is fixed
Frame 3 rear end, position is screwed into inner side from outside.
Described locating rack 3 rear end is higher than front end, and described fixing bolt 5 is arranged on the rear end of locating rack 3.
Described lock nut 4 has two, is arranged at locating rack 3 rear end.
Operation principle of the present utility model:
1, after the inner conical surface of the male cone (strobilus masculinus) of machine shaft 8 and test gear 7 being cleaned out, test gear 7 is touched in
On machine shaft 8, such as accompanying drawing 1.
2, being put in by this positioner on test gear 7, positioning screw 2 is placed between adjacent two teeth of test gear 7, twists
Fasten bolt 5, thus this positioner is fixed on test gear 7.
3, between the head and the end face of motor seal ring 6 of positioning screw 2, this motor type defined amount of being inserted in (sample is put into
Block thickness=regulation amount of being inserted in) sample block 1.
4, positioning screw 2 is tightened, with the head of positioning screw 2, sample block 1 is pressed on the end face of motor seal ring 6.
5, tighten locking nut 4, prevent positioning screw 2 to be subjected to displacement.
6, unclamp fixing bolt 5, take off this positioner, test gear 7 is heated.
7, the test gear 7 after heating is placed on the male cone (strobilus masculinus) of machine shaft 8, this positioner is put in again test
On gear 7, and tighten fixing bolt 5.
8, the test gear 7 installing positioner is pushed into positioning screw 2 head to contact with motor seal ring 6.
9, after test gear 7 shrinks, unclamp fixing bolt 5, take off this positioner, the hot jacket work of test gear 7
So far complete.
