Abstract
A steel threaded sleeve for connecting an aluminum box body consists of internal and external threads. The anti-loosening device is characterized in that an external thread embedded with an aluminum box body is manufactured on the outer wall of a cylinder, an internal thread matched with a connecting screw is manufactured on the inner wall of the cylinder, an anti-loosening toothed disc is manufactured at the end part of a steel threaded sleeve, and the connecting part of the anti-loosening toothed disc and the screw thread is provided with plastic reducing holes. After the external thread of the steel thread sleeve is screwed into the internal thread of the aluminum box, the end face of the anti-loosening fluted disc is completely attached to the aluminum box, the plastic deformation neck is deformed by the end face of the anti-loosening fluted disc under the action of pressure, and the anti-loosening fluted disc is completely embedded into the aluminum box.
Description
The utility model relates to a kind of thread bush that casing connects that is used for, especially for the steel thread bush of aluminium casing connection.
The gearbox that is used for transferring power in the present various mechanical industry, the connection of aluminium casing are to adopt the steel bolt directly to be screwed into the mode of aluminium casing internal thread.This connecting mode linking intensity is low, and anti-loosening property and abrasion resistance are poor, and is not easy to safeguard.Developed a kind of steel wire thread bush in order to address this problem China.Promptly the steel wire thread bush is screwed into the aluminium casing, joint bolt is screwed into the endoporus of steel wire thread bush then.The footpath only can be than the big 1.7 times of pitch in footpath in the internal thread during the steel wire thread bush was externally threaded.This connecting mode only can solve the wear problem of aluminium casing thread.
The purpose of this utility model provides a kind of steel thread bush that connects the aluminium casing, and it can not only improve the linking intensity of aluminium casing, and can improve locking property and wear resistance.
The purpose of this utility model is achieved in that a kind of connection aluminium casing steel thread bush (5), form by internal and external threads, it is characterized in that: on the outer wall of an entity garden tube, make the outside thread (1) of joining with the casing edge, make on the inwall and internal thread (2) that joint bolt (9) matches, the end of thread bush is shaped on locking fluted disc (3), the point of attachment of locking fluted disc (3) and screw thread is flow neck (4), the footpath, the end of locking fluted disc (3) tooth is greater than the external diameter of flow neck (4), and the footpath, the end of tooth is greater than the big footpath of steel thread bush outside thread (1).The internal diameter of flow neck (4) is greater than the big footpath of steel thread bush internal thread (2), and the external diameter of flow neck (4) is less than the path of steel thread bush outside thread (1).
Throw can screw in thread bush (5) in the aluminium casing (7), after treating that the lower end surface of locking fluted disc (3) of thread bush (5) and aluminium casing junction plane are all fitted, be press fit in the aluminium casing with the locking fluted disc (3) of hydraulic pressure assembly tool thread bush, because the effect of pressure makes flow neck (4) produce distortion and has prevented the loosening of thread bush, thereby guaranteed the linking intensity of screw thread, improved locking property and wear resistance.
Owing to adopt such scheme, the linking intensity that has thoroughly solved aluminium casing connection existence is low, the problem of anti-loosening property and antiwear property difference, help the care and maintenance in the using process, compare with the steel wire thread bush, steel thread bush anti-loosening property is good, and the outside thread size is not subjected to the restriction of internal thread size, makes easily.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the sectional drawing of steel thread bush.
Fig. 2 is the profile of tooth figure of locking fluted disc.
Fig. 3 is that the aluminium casing connects the assembling schematic representation.
On the outer wall of an entity garden tube, make the outside thread (1) of joining with casing (7) edge, make on the inwall and internal thread (2) that joint bolt (9) matches, the end of thread bush is shaped on locking fluted disc (3), the point of attachment of locking fluted disc (3) and screw thread is flow neck (4), the footpath, the end of locking fluted disc (3) tooth is greater than the big footpath of steel thread bush outside thread (1), the internal diameter of flow neck (4) is greater than the big footpath of steel thread bush internal thread (2), and the external diameter of flow neck (4) is less than the path of outside thread (1).Steel thread bush (5) is M12 * 1.5 with the outside thread (1) that aluminium casing (7) edge is joined, and the internal thread (2) that joint bolt (9) matches is M8 * 1.25, the external diameter φ 13.2 of locking fluted disc (3), 90 ° of tooth-shape angles, tooth number Z=25, fluted disc thickness are 1, the external diameter φ 9.5 of flow neck (4), internal diameter φ 8.5, neck length 4.5.Material is made chrome-faced or zinc-plated with steel 35.Seal ring (6) is enclosed within on the flow neck external diameter of steel thread bush, utilize throw that steel thread bush (5) is screwed in aluminium casing (7), treat that the end face of locking fluted disc (3) and aluminium casing (7) the junction plane back of all fitting all embeds in the aluminium casing (7) with the locking fluted disc (3) of hydraulic pressure assembly tool with steel thread bush (5), case lid (8) passes through screw (9), packing ring (10) connects with casing (7).
The design of steel thread bush has now formed seriation, and the moment of torsion that process evidence screw thread is born has surpassed the index of German automobiles industrial standard VDI-2230 considerably beyond design objective.Produce in batches in case form, can supply industries such as space flight, aviation, war industry, automobile, engineering machinery, select for use according to needs separately.
