Abstract
The present invention relates to fittings for large power apparatus, and is especially one overrunning unidirectional gear coupling. The novel coupling consists of bevel gear outer muff, spur gear outer muff, inner gear sleeve and connecting gear. It features the bevel gear outer muff of bevel gear of involute profile and meshed to inner bevel gear of the inner gear sleeve by means of side centering; the inner gear sleeve with spur gear meshed with the connecting gear; and the connecting gear meshed with the inner gear sleeve and the spur gear outer muff simultaneously. The present invention makes it possible for two pieces of power apparatus in dynamic running state to have their transmission chain separated and changed.
Description
Technical field
The invention belongs to mechanical manufacturing field, is the transmission COMM communication in the middle of two power equipments specifically.
Background technique
Typical gear coupling is made up of the inside and outside spur gear of two cover pairings, by middleware, rely on flank engagement to realize the transmission of the quick condition of two between centers motion, this transfer mode is applied widely, and having bigger axial and radial compensation ability, is a kind of use coupling very widely.But this type of coupling can't have under motion state in the transmission system of clutch requirement to be used.
Summary of the invention
The objective of the invention is defective at traditional coupling existence, developed a kind of novel coupler, adopt the spur gears of two cover pairings and the helical gear of a cover pairing to form new structure, in running, the Transmitted chains of two power equipments is disconnected fully becomes possibility.
A kind of overrunning unidirectional gear coupling is made up of the inside and outside spur gear of two cover pairings and the inside and outside helical gear of a cover pairing, and it comprises helical gear external tooth axle sleeve, spur gear external tooth axle sleeve, inner gear housing and each parts of connection gear, it is characterized in that:
A) helical gear external tooth axle sleeve right-hand member is the helical gear of involute profile, by the internal helical gear engagement of flank centering with the inner gear housing right-hand member, there is the axially movable axial limiting face of control with inner gear housing and connection gear pairing the centre, inner gear housing can move on helical gear external tooth axle sleeve, and left end has radial location circle to match with connection gear;
B) the axial limiting face that inner gear housing right-hand member helical teeth internal gear and helical gear external tooth axle sleeve engagement, centre have the control with helical gear external tooth axle sleeve pairing to be moved to the left, left end has the interior spur gear with the connection gear engagement;
C) the connection gear right-hand member has the engagement of spur gear and inner gear housing outward, in have the radial location circle to match with helical gear external tooth axle sleeve, there is the axial limiting face with helical gear external tooth axle sleeve coupling the centre, the connection gear left end has the interior spur gear that meshes with the external tooth axle sleeve;
The helical gear of the mating engagement of helical gear external tooth axle sleeve and inner gear housing replaces with the oblique spline with centering function; The interior external gear pump of inner gear housing and connection gear replaces with the diaphragm type structure with compensation ability.
Good effect of the present invention is that design science is reasonable, simple in structure; Because the new structure that adopts two pairs of spur gears and a pair of helical gear to match makes two power equipments under dynamic state of run, makes Transmitted chains accomplish not reach the switching fully of transcendent function with stopping, causes equipment operation safer, reliable; Because the inside and outside tooth cover of connection gear disengages fully, Transmitted chains disconnects fully, does not have friction, cuts down the consumption of energy significantly.
Description of drawings
Fig. 1, structure sectional view of the present invention, wherein: (1) straight-tooth external tooth axle sleeve, (2) connection gear, (3) gland, (4) inner gear housing, (5) helical teeth external tooth axle sleeve.
Embodiment
Further specify as follows to structure of the present invention and operation mechanism in conjunction with the accompanying drawings:
Embodiment 1
At first assemble the present invention.After being installed in inner gear housing 4 on the helical teeth external tooth axle sleeve 5, be installed on the machine shaft again; Then, after connection gear 2 and straight-tooth external tooth axle sleeve 1 be installed together, be contained on the rotating shaft of steam turbine; At last, with connection gear 2 right-hand members and the engagement of inner gear housing 4 left end spur gears; Gland 3 is covered, i.e. assembling finishes.
The operation mechanism explanation.When motor rotation, the rotational velocity of helical gear external tooth axle sleeve 5 is during greater than the rotational velocity of spur gear external tooth axle sleeve 1, under the effect of applied force, promotion inner gear housing 4 is moved to the left connection gear 2 and contacts with spur gear external tooth axle sleeve 1 end face, two gear positions with speed difference necessarily have one or two gear to be in the moment of corresponding engagement, because the speed difference of helical gear external tooth axle sleeve 5 and spur gear external tooth axle sleeve 1 causes that inner gear housing 4 and connection gear 2 certainly lead to and moves axially, blocked by the axial limiting face until inner gear housing, the axial limiting face that device is provided with makes gear displacement distance for quantitative.Helical gear external tooth axle sleeve 5 passes motion to spur gear external tooth axle sleeve 1 is synchronized with the movement motor and steam turbine; When the rotational velocity of the spur gear external tooth axle sleeve 1 on the rotating shaft of steam turbine during greater than the rotational velocity of helical gear external tooth axle sleeve 5, because the speed difference of helical gear external tooth axle sleeve 5 and spur gear external tooth axle sleeve 1 causes that inner gear housing 4 and connection gear 2 certainly lead to and moves axially, break away from fully until connection gear 2 and spur gear external tooth axle sleeve 1, then the speed of helical gear external tooth axle sleeve 5 and 1 each maintenance of spur gear external tooth axle sleeve oneself is rotated further.Steam turbine is when reaching certain high speed, and steam turbine can break away from motor voluntarily, continues operation voluntarily, guarantees the security of operation of steam turbine, motor, electrical network.
Design the unidirectional gear coupling that different gear backlash and the gap, location between component just can obtain different compensation abilitys.
Embodiment 2
The present invention is installed.On straight-tooth external tooth axle sleeve 1, install cover 2 in the connection gear, the opposite side of connection gear 2 and inner gear housing 4 engagements, the other end inner gear housing 4 of this spur gear is the oblique spline structure with centering function with helical teeth external axle sleeve 5.
Embodiment 3
Assembling the present invention.By this device that two cover spur gears and a cover helical gear constitute, the engagement spur gear of connection gear 2 and inner gear housing 4 can adopt diaphragm type structure to replace.Equally, can make two power equipments under dynamically, motor is accomplished separating fully between rotating shaft with the steamer function.
