Abstract
The utility model discloses an axially-limited anti-backlash gear, which comprises a basic gear blank (1), a movable gear blank (3), a spring (4) and an axial screw (2), wherein the middle of the axial screw (2) is provided with a projecting circular ring; a limiting distance exists between a screw head and the projecting circular ring; the movable gear blank (3) is in axial gap interference with the basic gear blank (1); one end of the spring (4) is hooked with the basic gear blank (1), and the other end of the spring (4) is hooked with the movable gear blank (3); the axial screw (2) is arranged in a through hole of the movable gear blank (3), and is tightly connected with the basic gear blank (1); when the basic gear blank (1) moves positively or negatively together with a matched gear, the basic gear blank (1) or the movable gear blank (3) is always meshed with a meshing gear; and meanwhile, the axial screw (2) is screwed with the basic gear blank (1), so that loosening is prevented during long-period running. According to the axially-limited anti-backlash gear, an anti-backlash function is ensured, and the basic gear blank (1) and the movable gear blank (3) are prevented from being loosened under a long-time running condition.
Description
Technical field
The utility model relates to a kind of clearance elimination gear, particularly a kind of axial limiting clearance elimination gear.
Background technique
Gear and gear meshing all have backlash, need when gear pair under the situation of positive and negative rotation, and between cog can produce certain backlash amount.Therefore, accurately feed back in the launcher of angle measurement, need the design clearance elimination gear so that eliminate the backlash amount at needs.Clearance elimination gear in the past is for to design two identical gear sheets at gear pair one end, and two gear sheets connect through spring, and guaranteeing it no matter is just to change or reverse, thereby clearance elimination gear all reaches the purpose in the crack that disappears with the engaging gear tight engagement.Simultaneously spacing for the axis of the two gear sheets that guarantee clearance elimination gear, traditional method connects through pin or is threaded.But this method has following shortcoming: if 1. pin or screw in compression power are too big, thereby the spring force that can cause connecting clearance elimination gear loses the function in the crack that disappears less than the frictional force of two face of gears; 2. if pin or screw in compression power are too little, under long shock conditions, thereby pin or screw can get loose and make two gear sheets lose axial limiting cause finally the disappearing inefficacy of crack function.
The model utility content
The utility model purpose is to provide a kind of axial limiting clearance elimination gear, if solve pin or screw in compression power too big, thereby the spring force that can cause connecting clearance elimination gear loses the function in the crack that disappears less than the frictional force of two face of gears; If pin or screw in compression power are too little, under long shock conditions, thereby pin or screw can get loose and make two gear sheets lose axial limiting cause finally the disappearing problem of crack disabler.
A kind of axial limiting clearance elimination gear comprises: basic tooth embryo, moving tooth embryo, spring also comprise: axial screw.Wherein, a chime rings is arranged, limited determining deviation between screw head and chime rings in the middle of the axial screw.Moving tooth embryo and basic tooth plumular axis Spielpassung, spring one end and basic tooth embryo clasp joint, the other end and moving tooth embryo clasp joint, axial screw place in the through hole of moving tooth embryo, and closely are connected with basic tooth embryo, and be gapped between axial screw head and moving tooth embryo.
When basic tooth embryo when the gear of cooperation moves because moving tooth embryo is connected with spring with basic tooth embryo, no matter is just changeing still and reversing; Base tooth embryo or moving tooth embryo always mesh with engaging gear; Simultaneously, because axial screw and basic tooth embryo are tightened, guaranteed when long-term operation, not get loose.
The utility model has guaranteed that basic tooth embryo and moving tooth embryo do not get loose under the situation of long-time running, thereby screw-down torque just acts on and guaranteed side set that spring can will move tooth embryo and the basic tooth embryo function in crack that realized disappearing on the basic tooth embryo simultaneously.
Description of drawings
Fig. 1: a kind of axial limiting clearance elimination gear is formed schematic representation.
1. basic tooth embryo 2. axial screws 3. moving tooth embryo 4. springs.
Embodiment
A kind of axial limiting clearance elimination gear comprises: basic tooth embryo 1, moving tooth embryo 3, spring 4 also comprise: axial screw 2.Wherein, a chime rings is arranged, limited determining deviation between screw head and chime rings in the middle of the axial screw 2.Moving tooth embryo 3 cooperates with basic tooth embryo 1 between centers crack, and spring 4 one ends and basic tooth embryo 1 clasp joint, the other end and moving tooth embryo 3 clasp joints, axial screw 2 place in the through hole of moving tooth embryo 3, and closely is connected with basic tooth embryo 1, and 2 of axial screws and 3 of moving tooth embryos are gapped.
When basic tooth embryo 1 moves with the gear that cooperates,, no matter just changeing still counter-rotating because moving tooth embryo 3 is connected with basic tooth embryo 1 usefulness spring 4; Base tooth embryo 1 or moving tooth embryo 3 always mesh with engaging gear; Simultaneously, because axial screw 2 is tightened with basic tooth embryo 1, guaranteed when long-term operation, not get loose.
Claims (1)
1. axial limiting clearance elimination gear comprises: basic tooth embryo (1), moving tooth embryo (3), spring (4) is characterized in that also comprising: axial screw (2); Wherein, a chime rings is arranged, limited determining deviation between screw head and chime rings in the middle of the axial screw (2); Moving tooth embryo (3) cooperates with basic tooth embryo (1) between centers crack; Spring (4) one ends and basic tooth embryo (1) clasp joint; The other end and moving tooth embryo (3) clasp joint; Axial screw (2) places in the through hole of moving tooth embryo (3), and closely is connected with basic tooth embryo (1), and is gapped between axial screw (2) head and moving tooth embryo (3);
When basic tooth embryo (1) moves with the gear that cooperates; Because moving tooth embryo (3) is connected with spring (4) with basic tooth embryo (1); No matter just changeing still counter-rotating, basic tooth embryo (1) perhaps moving tooth embryo (3) federation and engaging gear engagement, simultaneously; Because axial screw (2) is tightened with basic tooth embryo (1), has guaranteed when long-term operation, not get loose.
