Specific embodiment
With reference to specification drawings and specific embodiments, the present invention is further described.
As shown in figure 1, the present invention is a kind of lowering or hoisting gear, described lowering or hoisting gear specific embodiment includes tooth bar 7, electricity Motivation 9, tooth rest 10, housing 8 and multiple gear, described motor 9, tooth rest 10, housing 8 and multiple gears are located at housing Inside 8.
Described tooth bar 7 is placed vertically, and through housing 8, the connection of tooth bar 7 needs the object of lifting, described tooth bar 7 and Number gear 1 is meshed, and a gear 1 and No. two gears 2 collectively constitute a duplicate gear, and the axle of duplicate gear is arranged on described On housing 8.The described output shaft of motor 9 connects No. three gears 3, and No. three gears 3 are meshed with No. two described gears 2.
Axle where 1, No. two gears of described tooth rest 10 and a gear 2 is hinged, by housing 8 come limiting gear The angle of the rotation of frame 10, the position limiting structure of the limitation can be the external shape of housing 8, or the protrusion in housing 8.It is described Motor 9 be fixedly connected with tooth rest 10.Because tooth rest 10 is around the axle rotation where No. two gears 2, so rotating through Cheng Zhong, No. three gears 3 can be meshed with No. two gears 2 all the time.
The lower section of No. two gears 2 is provided with No. four gears 4, and No. four gears 4 are meshed with No. two gears 2, and No. four gears 4 are fixed A coaxial pocket-wheel 11 of connection.No. four gears 4 and an axle for pocket-wheel 11 are arranged on described housing 8.Described Tooth rest 10 is provided with intermeshing No. five gears 5 and No. six gears 6, and No. five gears 5 and No. six gears 6 are respectively fixedly connected with Coaxial No. two pocket-wheels 12 and No. three pocket-wheels 13.Three described pocket-wheels are located on same perpendicular, and are met： 1. No. two pocket-wheels 12 and No. three maximum radius of pocket-wheel 13（Distance i.e. between sharp corner and the center of circle）Sum is less than No. five gears 5 With No. six reference radius sums of gear 6, to ensure that No. two pocket-wheels 12 will not collide with No. three pocket-wheels 13；2. tooth is worked as Wheel carrier 10 is rotated during to lowest part, and the wedge angle and No. three wedge angles of pocket-wheel 13 of No. two pocket-wheels 12 can be with a pocket-wheels 11 wedge angle collides；3. when tooth rest 10 is rotated to highest point, No. two wedge angles and No. three pocket-wheels 13 of pocket-wheel 12 Wedge angle can not all be collided with the wedge angle of a pocket-wheel 11.Under gravity, during nature, tooth rest 10 In the lowest part of its stroke.
Lowering or hoisting gear operation principle：When the object band carry-over bar 7 for needing lifting declines, a gear 1 turns clockwise, No. two gears 2 turn clockwise simultaneously, and No. two gears 2 drive No. four rotate counterclockwises of gear 4, while an inverse time of pocket-wheel 11 Pin rotates, and a wedge angle of pocket-wheel 11 collides with No. two wedge angles of pocket-wheel 12 first, and No. two pocket-wheels 12 turn clockwise, together When No. five gears 5 turn clockwise, drive No. six rotate counterclockwises of gear 6, while No. three rotate counterclockwises of pocket-wheel 13, immediately A number wedge angle of pocket-wheel 11 collides with No. three pocket-wheels 13 just in rotate counterclockwise, inverts No. three pocket-wheels 13, i.e., suitable Hour hands rotate, while No. six gears 6 turn clockwise, No. five rotate counterclockwises of gear 5 are driven, while No. two inverse times of pocket-wheel 12 Pin rotates, and a next wedge angle for pocket-wheel 11 is collided with No. two pocket-wheels 12 just in rotate counterclockwise immediately ... passes through The collision for going round and beginning again a, rotating speed for pocket-wheel 11 is controlled in a relatively low speed all the time, that is, realize tooth bar 7 slow The process of decline.Slow drop process is mechanically to realize, without starting motor 9, so as to reduce energy loss；It is slow Drop process realized by collision rather than friction mode, thus will not cause because of the abrasion of part coefficient of friction change and then Descending speed is set to change.
When the object for needing lifting needs to rise, start motor 9, motor 9 drives the dextrorotation of No. three gears 3 Turn, No. three gears 3 drive No. two rotate counterclockwises of gear 2, while a rotate counterclockwise of gear 1, a gear 1 is with carry-over bar 7 slow risings；No. three gears 3 are subject to No. two torques counterclockwise of the effect of gear 2 simultaneously, and tooth rest 10 is subject to No. three gears 3 The clockwise torque of effect, the torque drives tooth rest 10 to rotate clockwise in figure at double dot dash line position, now No. two stars Shape wheel 12 no longer collides with No. three pocket-wheels 13 with a pocket-wheel 11, it is to avoid energy loss.
In prioritization scheme, to obtain preferably slowing effect, a diameter of gear 1 is less than No. two diameters of gear 2, No. two teeth , with diameter greater than No. four diameters of gear 4, No. four diameters of gear 4 are less than a maximum gauge for pocket-wheel 11 for wheel 2（That is sharp corner and circle The twice of distance between the heart）.
In present invention could apply to various machine applications, below for specific implementation is applied.Lifting in following embodiments Apparatus structure is specially the present invention, sees above-mentioned specific embodiment in composition and annexation in it, below its repeating part not Tire out again and state.
Embodiment one is a kind of lifting device.
