Abstract
The utility model relates to an improved grail gear structure which comprises a grail gear, and a grail for supporting the grail gear, wherein the contact surface of the grail and the grail gear is a stepped conical surface and comprises one main contact surface and at least one standby contact surface, an adjusting clearance is left for the standby contact surface, and a wear-resisting block is arranged between the grail and the grail gear. By virtue of the stepped conical surface contact between the grail and the grail gear, circumferential positioning precision can be improved; and by adding the standby contact surface, when precision of the main contact surface is reduced, the thickness of the wear-resisting block can be adjusted to enable the standby contact surface to be used so as to realize precision improvement, so that the use precision of a machine is effectively improved, and the service life of the machine is prolonged.
Description
Technical field
The utility model relates to a kind of improved deep bid gear structure, the deep bid gear structure of particularly a kind of positioning accuracy height, long service life.
Background technology
Whether just at present, existing most of circular knitting machines are to drive the syringe mode by toothed disc to carry out knitting action, so toothed disc circle rotation, and direct relation knitting quality.The deep bid of general knitting machine mostly is the straight line cylinder with the contact form of deep bid gear on running cooperates and contacts, and being provided with wear plate between deep bid and deep bid gear realizes supporting and the location, and wear plate itself does not play the circumferential registration effect, and deep bid is by realizing cooperating of gap with circumferential registration between the deep bid gear.And this kind mode is under long working, contact-making surface between deep bid gear and the deep bid can produce wearing and tearing, contact gap between deep bid gear and the deep bid is increased gradually, cause the circumferential registration precision to reduce, the deep bid gear produces rotating deviation, thereby reduce the precision of board, influence the knitting quality of board and the life-span of board.
Summary of the invention
Main purpose of the present utility model is the shortcoming that overcomes prior art, and the deep bid gear structure of a kind of positioning accuracy height, long service life is provided.
The utility model adopts following technical scheme:
A kind of improved deep bid gear structure comprises deep bid gear and the deep bid that is used to support this deep bid gear, and this deep bid contacts for the ladder conical surface with the contact-making surface of deep bid gear, and this contact-making surface comprises a main contact-making surface and at least one standby contact-making surface.
Be provided with wear-resistant block between described deep bid and the deep bid gear.
Described standby contact-making surface leaves the control gap.
Described control gap is of a size of 0.01-1mm.
Described main contact-making surface is positioned at below, and described standby contact-making surface sets gradually above this main contact-making surface.
Perhaps, described main contact-making surface is positioned at the top, and described standby contact-making surface sets gradually below this main contact-making surface.
By above-mentioned to description of the present utility model as can be known, compared with prior art, the beneficial effects of the utility model are: because deep bid contacts for the ladder conical surface with the contact-making surface of deep bid gear, so can improve its circumferential registration precision; Increased standby contact-making surface, and this standby contact-making surface leaves the control gap, thereby when main contact-making surface generation precise decreasing, can adjust the thickness of wear-resistant block and reinstate the raising that standby contact-making surface is realized precision, thereby effectively improve the service precision of board, prolong the service life of board.
Description of drawings
Fig. 1 is the cross-sectional view of the utility model specific embodiment.
Among the figure: 1. deep bid, 2. deep bid gear, 3. main contact-making surface, 4. standby contact-making surface, 5. wear-resistant block.
The specific embodiment
Below the utility model will be further described by the specific embodiment.
With reference to Fig. 1, a kind of improved deep bid gear structure of the present utility model, comprise deep bid gear 2 and the deep bid 1 that is used to support this deep bid gear 2, this deep bid 1 contacts for the ladder conical surface with the contact-making surface of deep bid gear 2, and this contact-making surface comprises a main contact-making surface 3 and a standby contact-making surface 4, this standby contact-making surface 4 leaves the control gap, this control gap is of a size of 0.01-1mm, this main contact-making surface 3 is positioned at below, this standby contact-making surface 4 is arranged on the top of this main contact-making surface 3, is provided with wear-resistant block 5 between this deep bid 1 and the deep bid gear 2.
With reference to Fig. 1, deep bid 1 of the present utility model contacts for the ladder conical surface with the contact-making surface of deep bid gear 2, therefore can improve the circumferential registration precision on running cooperates; And increased a standby contact-making surface 4, this standby contact-making surface 4 leaves the control gap, thereby when precise decreasing takes place main contact-making surface 3, can adjust the thickness of wear-resistant block 5 and reinstate the raising that standby contact-making surface 4 is realized precision, thereby effectively improved the service precision of board, prolonged the service life of board.
Above-mentioned only is a specific embodiment of the present utility model, but design concept of the present utility model is not limited thereto, and allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
