Detailed Description
As shown in fig. 1 and 2, the motor test half-coupling 16 of the present invention includes an inner sleeve 7 and an outer sleeve 10. The inner sleeve 7 is provided with an inner sleeve shaft hole 8, and the inner sleeve shaft hole 8 is provided with a key groove 9 which can be connected with an output shaft of the motor. The inner sleeve 7 is also provided with an outer conical surface 15, an inner sleeve flange 4 is arranged at the large end of the outer conical surface 15, and an inner sleeve through hole 3 is arranged on the inner sleeve flange 4. The outer sleeve 10 has an inner conical surface which cooperates with the outer conical surface 15. When the outer conical surface 15 is abutted against the inner conical surface, an inner sleeve gap 13 is formed between the inner sleeve flange 4 and the outer sleeve 10, an outer sleeve threaded hole 11 is formed in the outer sleeve 10 corresponding to the inner sleeve through hole 3, the inner hexagonal bolt 12 penetrates through the inner sleeve through hole 3 to be in threaded connection with the outer sleeve 10, and a stud can be arranged on the outer sleeve 10 and penetrates through the inner sleeve through hole 3 and is connected with a nut. Therefore, the bolt or the nut can be used as a screwing device to tightly press the inner sleeve 7 and the outer sleeve 10, so that the inner sleeve 7 and the outer sleeve 10 are matched through conical surfaces, the concentricity of the inner sleeve 7 and the outer sleeve is guaranteed, and the torque is transmitted by the aid of great friction force between the inner sleeve 7 and the outer sleeve. The tightening device is preferably a bolt in this embodiment because the related structure is more compact.
The motor test half coupling arranged in the above way can be realized by equipping different inner sleeves 7 for motors with various shaft diameters and replacing the inner sleeves in the test. Because the device can repeatedly use the outer sleeve 10, compared with the prior scheme, the device saves the manufacturing material of the outer sleeve 10, improves the material utilization rate, and because the inner sleeve 7 is relatively smaller, the space occupied by storing the inner sleeve 7 with multiple specifications is relatively smaller than that occupied by storing the prior half coupling with multiple specifications, thereby reducing the storage cost of equipment.
The outer sleeve 10 of the utility model can be connected with the existing half-coupling 17 by adopting a jaw type structure or a flange type structure; the preferred embodiment is a flange structure with simple structure and convenient manufacture, i.e. the coupling flange 1 is arranged at the large end of the inner conical surface, and the coupling flange 1 is provided with a flange through hole 2.
Because flange formula half-coupling's flange should be close to the outer end as far as possible, the flange terminal surface that makes two half-couplings of constituteing the shaft coupling is close to as far as possible (as shown in fig. 3), and flange through-hole 2 on the half-coupling flange 1 of both sides aligns the back to the reaming hole bolt (not shown in the figure) atress that makes to pass flange through-hole 2 is better, and its shear force that receives is littleer promptly, so the utility model discloses a motor is experimental with half-coupling is provided with the outer cover heavy groove 14 that the diameter is greater than endotheca flange 4 at half-coupling flange 1's outer terminal surface, is provided with the diameter on endotheca flange 4 and is. This minimizes the formation of the flange end faces projecting beyond the coupling flange 1. Furthermore, the depth of the outer sleeve sinking groove 14 is more than or equal to the sum of the thickness of the inner sleeve flange 4 and the inner and outer sleeve gaps 13; the depth of the inner sleeve sinking groove is greater than or equal to the height of the head of the bolt. Thus, no protruding structure is arranged on the flange end surface of the flange 1 of the half coupling, and the connection of the half coupling is facilitated.
Used the utility model discloses a motor is shaft coupling of half-coupling for experiment except connecting the reamed hole bolt in the flange through-hole 2 of both sides, still can use the nylon rope winding to connect, even use the nylon rope to pass another group of flange through-hole 2 in proper order after passing the corresponding a set of flange through-hole 2 in both sides again, whole flange through-hole 2 winding connection system again. Therefore, the two half-couplings are flexibly connected, the flange end faces of the two half-couplings can be tightly attached without excessively emphasizing the stress of a bolt, the input shaft of a testing instrument connected with the shaft hole 18 of the existing half-coupling and the output shaft of a motor are not required to be accurately and coaxially installed, and the installation efficiency and convenience in the test are improved.
In addition, in order to ensure the contact effect of conical surface matching and prevent the side skew phenomenon, the outer conical surface 15 and the inner conical surface need to be uniformly pressed on the circumference when matching, so the device is provided with 3 inner sleeve through holes 3, and the 3 inner sleeve through holes 3 are uniformly distributed on the inner sleeve flange 4 in the circumferential direction by taking the axis of the outer conical surface 15 as the axis; and is provided with outer sleeve threaded holes 11 and inner hexagon bolts 12 which are in one-to-one correspondence with the inner sleeve through holes 3.
Further, since the inner sleeve 7 is not likely to come off when the inner sleeve 7 is detached from the outer sleeve 10 due to the large interaction force of the taper surface fitting, 2 or more (preferably 3 in this embodiment) screw through holes 5 are uniformly distributed in the circumferential direction on the inner sleeve flange 4 with the axis of the outer taper surface 15 as the axis. As shown in fig. 2, during the disassembly, a bolt can be screwed into the threaded through hole 5, and the bolt can drive the inner sleeve 7 to be separated from the outer sleeve 10 after abutting against the outer sleeve sinking groove 14.
