When transmission shaft works under hot operating mode, operating temperature is higher, and its axle thermal expansion amount is larger; But transmission shaft is cold conditions when mounted, therefore can cause the installation dimension of transmission shaft and working size inconsistent.If carry out installing not regulating according to the actual size under transmission shaft cold conditions, equipment so may be caused normally to work, serious meeting damage equipment or cause security incident.
Traditional method reserves assemblage gap based on experience value in the process of installing; But the thermal expansion amount of the transmission shaft under different thermal condition is different, axial length change is different.The steady state of the transmission shaft worked under therefore only relying on empirical value preset clearance cannot meet all hot operating modes.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of regulating device of transmission shafts to prestretching amount that automatically can adapt to axial length change under the hot operating mode of transmission shaft.
The utility model solves the technological scheme that its technical problem adopts: transmission shafts, to the regulating device of prestretching amount, comprises adjustment dottle pin, expansion device, the second shaft coupling of being arranged on the first shaft coupling on coupling shaft and being arranged on transmission shaft;
Described adjustment dottle pin and expansion device are arranged between the first shaft coupling and the second shaft coupling, and described expansion device is arranged on the first shaft coupling; Described expansion device is between adjustment dottle pin and the first shaft coupling; Described first shaft coupling and the second shaft coupling removably connect.
Preferably, described expansion device comprises stage clip, trim ring; Described stage clip is arranged between the first shaft coupling and trim ring, and described stage clip is pressed between the first shaft coupling and trim ring by trim ring; Described trim ring is connected with the first shaft coupling by bolt; Described trim ring is between adjustment dottle pin and stage clip.
Preferably, described first shaft coupling and the second shaft coupling are bolted.
The beneficial effects of the utility model are: transmission shafts described in the utility model to the regulating device of prestretching amount, due to be provided with between the first shaft coupling and the second shaft coupling expansion device and adjustment dottle pin; Therefore when main axis of expansion is to length under hot operating mode for transmission shaft, by compression expansion device thus offset the increasing amount of transmission shaft axial length, ensure the normal operation of equipment.Simultaneously can by regulating the size of adjustment dottle pin in the process of installing, the maximal dilation amount of adjustment expansion device.To the adjustment of transmission shafts to prestretching amount when realizing installing.Therefore transmission shafts described in the utility model is to the regulating device of prestretching amount, and under can avoiding transmission shaft thermal condition, axial length increases the impact normally worked on equipment, ensures the normal operation of equipment, the stability that the equipment that improves runs and Security.Reduce installation requirement simultaneously, be convenient to the installation of transmission shaft, reduce the installation time, reduce installation cost.
Accompanying drawing explanation
Fig. 1 be in the utility model embodiment transmission shafts to the regulating device of prestretching amount;
Indicate in figure: 1-coupling shaft, 2-first shaft coupling, 3-stage clip, 4-trim ring, 5-adjusts dottle pin, 6-second shaft coupling, 7-transmission shaft.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1, transmission shafts described in the utility model, to the regulating device of prestretching amount, comprises adjustment dottle pin 5, expansion device, the second shaft coupling 6 of being arranged on the first shaft coupling 2 on coupling shaft 1 and being arranged on transmission shaft 7;
Described adjustment dottle pin 5 and expansion device are arranged between the first shaft coupling 2 and the second shaft coupling 6, and described expansion device is arranged on the first shaft coupling 2; Described expansion device is between adjustment dottle pin 5 and the first shaft coupling 2; Described first shaft coupling 2 and the second shaft coupling 6 removably connect.
The Main Function of described expansion device can realize stretching, thus realize increase or the minimizing of shaft coupling end face axial length.
In the process of installing, can by regulating the thickness of adjustment dottle pin 5, thus make after mounting, the adjustment dottle pin 5 between the first shaft coupling 2 and the second shaft coupling 6 extrudes the difference of the amount of compression of expansion device, the maximal dilation amount of adjustment expansion device; Thus regulate the maximum shortening length of axial length of coupling.
Working principle:
When transmission shaft 7 is under hot operating mode, transmission shaft 7 expands, and axial length increases, and therefore transmission shaft 7 drives the second shaft coupling 6 to extrude the first shaft coupling 2.Owing to being provided with adjustment dottle pin 5 and expansion device between the first shaft coupling 2 and the second shaft coupling 6, therefore the second shaft coupling 6 extrudes adjustment dottle pin 5, and adjustment dottle pin 5 extrudes expansion device.Because expansion device can stretch, therefore when expansion device be adjusted dottle pin 5 extrude time, expansion device shrink, thus offset amount of compression.Therefore balanced out the axial length increasing amount of transmission shaft 7 by the contraction of expansion device, thus ensure the normal operation of equipment all the time.When transmission shaft 7 quit work return to normal temperature time, axial length shortens, and is recovered thus compensate the shortening amount of transmission shaft 7 length direction by expansion device.
In sum, transmission shafts described in the utility model to the regulating device of prestretching amount, due to be provided with between the first shaft coupling 2 and the second shaft coupling 6 expansion device and adjustment dottle pin 5; Therefore, when main axis of expansion is to length under hot operating mode for transmission shaft 7, by compressing the contraction of expansion device, thus offsetting the increasing amount of transmission shaft 7 axial length, ensureing the normal operation of equipment.Simultaneously can by regulating the size of adjustment dottle pin in the process of installing, the maximal dilation amount of adjustment expansion device.Adjustment to the axial prestretching amount of transmission shaft 7 when realizing installing.Therefore transmission shafts described in the utility model is to the regulating device of prestretching amount, and under can avoiding transmission shaft 7 thermal condition, axial length increases the impact normally worked on equipment, ensures the normal operation of equipment, the stability that the equipment that improves runs and Security; Reduce installation requirement simultaneously, be convenient to the installation of transmission shaft, reduce the installation time, reduce installation cost.
Described expansion device can adopt various ways, such as directly adopts spring, and for the ease of installing the stability ensureing structure simultaneously, preferably, as shown in Figure 1, described expansion device comprises stage clip 3, trim ring 4; Described stage clip 3 is arranged between the first shaft coupling 2 and trim ring 4, and described stage clip 3 is pressed between the first shaft coupling 2 and trim ring 4 by trim ring 4; Described trim ring 4 is connected with the first shaft coupling 2 by bolt; Described trim ring 4 is between adjustment dottle pin 5 and stage clip 3.Because stage clip 3 is pressed between the first shaft coupling 2 and trim ring 4 by trim ring; Therefore in the engineering of work, position is not easily moved, thus is conducive to the stability of structure.
Described first shaft coupling 2 and the second shaft coupling 6 can adopt the multiple mode such as seizing type that removably connects.In order to make structure simple, be convenient to install and dismounting, preferably, described first shaft coupling 2 and the second shaft coupling 6 are bolted simultaneously.
