Abstract
The utility model relates to an automatic synchronizing clutch, in particular to an automatic synchronizing clutch of a steam turbine turning gear, which aims to resolve problems that a steam turbine rotor can generate axial heat expansion at high temperature so that a ratchet and a pawl can not be ratcheted and driving teeth can not be jointed. The ratchet is mounted in an inner cavity of one end of a sliding part, the ratchet is fixedly connected with the sliding part integrally, driving inner teeth are processed on the inner wall of the other end of the sliding part, a hub is sleeved on the sliding part, the hub and the sliding part are connected via spiral teeth, an outer gear ring is disposed in the sliding part, driving outer teeth are processed on the outer side wall of one end of the outer gear ring corresponding to the driving inner teeth, the pawl is mounted at the other end of the outer gear ring, tooth width of the ratchet ranges from 72mm to 100mm, and tooth width of the driving inner teeth ranges from 59.3 mm to 70mm. when the rotor is in axial heat expansion, the ratchet and the pawl can be still ratcheted so as to lead the sliding part to slide, and the driving teeth can be jointed correctly, thereby increasing use safety and maintainability of the clutch.
Description
Technical field
The utility model relates to a kind of self-synchronizing clutch, is specifically related to the self-synchronizing clutch that a kind of rolling gear of turbine is used.
Background technique
At present, self-synchronizing clutch has been widely used in military products, chemical industry, metallurgy, every field such as energy-conservation, and the working principle of self-synchronizing clutch is automatically to realize engaging, throwing off according to the rotating speed of master and slave moving axis.When clutch is used for Turbine Barring Gears, a problem can appear, and be that traditional self-synchronizing clutch is indeterminable.Axial thermal expansion at high temperature can take place in turbine rotor, swell increment is approximately 40mm, if existing self-synchronizing clutch is used for Turbine Barring Gears, click can occur can not close by sour jujube, the situation that driving gear can not engage has had a strong impact on turbine work efficient.
The model utility content
When the utility model is used for Turbine Barring Gears in order to solve with existing self-synchronizing clutch, because axial thermal expansion at high temperature can take place in turbine rotor, cause click not close the problem that can not engage by sour jujube with driving gear, and then the self-synchronizing clutch that provides a kind of rolling gear of turbine to use.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: the self-synchronizing clutch that a kind of rolling gear of turbine described in the utility model is used comprises wheel hub, sliding component, external toothing, ratchet and pawl, described sliding component is a cylindrical shell, ratchet is installed in the inner chamber of sliding component one end and the two fixes as one, be processed with the driving internal tooth on the inwall of the sliding component the other end, wheel hub is sleeved on the sliding component and between the two and is connected by helical tooth, external toothing is arranged in the sliding component, be processed with the driving external tooth on the outer side wall of the end that external toothing is corresponding with driving internal tooth, ratchet is installed in the other end of external toothing; The facewidth of ratchet is 72mm～100 mm, and the facewidth that drives internal tooth is 59.3mm～70mm.In use, external toothing is installed on the turbine rotor.
The beneficial effects of the utility model are: the facewidth of the ratchet of the existing self-synchronizing clutch of the utility model by will being used for Turbine Barring Gears and drive the facewidth lengthening of internal tooth, like this when the rotor axial thermal expansion, click still can close by sour jujube, make the sliding component slippage, and driving gear (drive internal tooth and drive external tooth) also can be correct joint, solve the problem that steam turbine rotor shaft is brought when thermal expansion, improved Security and maintenance that clutch uses.Clutch after the improvement can satisfy the demand of the rotor axial thermal expansion of Turbine Barring Gears.
Description of drawings
Fig. 1 is not throw-out-of clutch figure during axial thermal expansion of rotor, throw-out-of clutch figure when Fig. 2 is rotor axial thermal expansion 40mm, and Fig. 3 is not clutch figure during axial thermal expansion of rotor, clutch figure when Fig. 4 is rotor axial thermal expansion 40mm.
Embodiment
Embodiment one: referring to Fig. 1～4, the self-synchronizing clutch that the described a kind of rolling gear of turbine of present embodiment is used comprises wheel hub 1, sliding component 4, external toothing 7, ratchet 9 and ratchet 8, described sliding component 4 is a cylindrical shell, ratchet 9 is installed in the inner chamber of sliding component 4 one ends and the two fixes as one, be processed with on the inwall of sliding component 4 the other ends and drive internal tooth 5, wheel hub 1 is sleeved on the sliding component 4 and between the two and is connected by helical tooth, external toothing 7 is arranged in the sliding component 4, be processed with on the outer side wall of the end that external toothing 7 is corresponding with driving internal tooth 5 and drive external tooth 6, ratchet 8 is installed in the other end of external toothing 7; The facewidth L1 of ratchet 9 is 72mm～100 mm, and the facewidth L2 that drives internal tooth 5 is 59.3mm～70mm.In use, external toothing 7 is installed on the turbine rotor 10.
As shown in Figure 1, the axial distance that drives between external tooth 6 and the driving internal tooth 5 is 3mm;
As shown in Figure 2, as rotor axial thermal expansion 40mm, promptly rotor moves axially 40mm left, and the axial distance that drives between external tooth 6 and the driving internal tooth 5 is 43mm;
As shown in Figure 3, when wheel hub 1 with rotor 10 synchronization and when the trend of surmounting is arranged, ratchet 9 on the sliding component 4 will withstand the ratchet 8 on the external toothing 7, be that click produces sour jujube cooperation usefulness, impel sliding component 4 for the helical movement along spline tooth, promptly sliding component 4 relative rotors 10 axially move, and make driving internal tooth 55, driving external tooth 6 enter engagement, and tooth and tooth are close to, clutch;
As shown in Figure 4, the engaging process of clutch is consistent with process among Fig. 3; By among Fig. 4 as can be seen, behind driving gear internal tooth 5 and the ratchet 9 width lengthening, can eliminate the influence that the rotor axial thermal expansion brings, clutch still can be engaged.
Embodiment two: the facewidth L1 of the described ratchet 9 of present embodiment is 90 mm, and the facewidth L2 that drives internal tooth 5 is 65mm.Other composition and annexation are identical with embodiment one.
