Abstract

The utility model provides a novel disc knitting machine for effectively preventing a gear ring from being eccentrically worn, which comprises a big disc and the gear ring arranged above the big disc. At least four positioning columns are evenly distributed on the upper surface of the big disc along the circumferential direction, a conical contracting surface is arranged at the upper end of each positioning column, an annular groove matching with the conical contracting surface is arranged on the lower surface of the gear ring, and a wearing layer is respectively arranged on the inner side surface and the outer side surface in the annular groove, the conical contracting surface on each positioning column is contacted with the annular groove, thereby the relative positioning of the gear ring in the radial direction during the running process is realized, the wearing layers on the inner side surface and the outer side surface in the annular groove are contacted with the conical contracting surfaces with higher fineness, the friction force is small, and the running is reliable and stable.

Description

A kind of novel circular disc knitting machine

Technical field

The utility model relates to a kind of novel circular disc knitting machine, belongs to the Knitting Machinery field.

Background technology

With reference to figure 1, known circular disc knitting machine generally comprises deep bid 1, gear ring 2 and is located at the cylinder seat 3 of gear ring 2 tops, and described gear ring 2 makes by spheroidal graphite cast-iron is one-body molded with cylinder seat 3, and gear ring 2 can be made circular motion with respect to deep bid 1.The steel wire slide rail of four rectangular arranged is set between the upper surface of gear ring 2 lower surfaces and deep bid 1 at present, steel wire is that special alloy is made, heat treatment process forms, and in the middle of four steel wire slide rails plurality of balls is set, and nationality is slowed down the wearing and tearing of two contact-making surfaces by the rolling action of ball.But between deep bid 1 and tooth Fig. 2, also have a vertical contact-making surface 12 to exist sliding friction to cooperate equally, because gear ring 2 external diameters make that with the radial load effect that side of travelling gear 4 engaged transmission is subjected to vertical contact-making surface 12 relative wears of same radial position are bigger, when circular disc knitting machine after row fortune after a while, concentricity is inconsistent during gear ring 2 runnings, float such as the cloth surface horizontal stripe male and female face that causes knitting influence product quality.Because gear ring 2 is integrated with cylinder seat 3, need change together with cylinder seat 3 when changing gear ring 2 simultaneously, the maintaining cost is higher.The Chinese patent CN2378407Y that announced on May 17th, 2000 discloses the lubricating structure of a kind of knitting machine deep bid and gear ring, it is that the edge face that cooperates with gear ring at the deep bid top offers into chute and backflash, the oil circulation system of band filter is gone into chute and is communicated with backflash and plays double action lubricated and filtration with described respectively, but this technical scheme does not still solve the vertical contact-making surface eccentric wear with deep bid of gear ring problem.

The utility model content

The purpose of this utility model provides a kind of novel circular disc knitting machine that effectively prevents the gear ring eccentric wear.

The technical scheme that the utility model adopted is such: a kind of novel circular disc knitting machine, comprise deep bid and be located at the gear ring of deep bid top, described deep bid upper surface along the circumferential direction is evenly equipped with at least four reference columns, described each reference column upper end is provided with the taper contraction front, described gear ring lower surface offers and the suitable cannelure of described taper contraction front, along the radial direction of gear ring, described cannelure medial surface and lateral surface are respectively equipped with one deck wearing layer.

By adopting the aforementioned techniques scheme, after gear ring is located on the deep bid, symmetrically arranged reference column contacts with cannelure by the taper contraction front, thereby realize the relative positioning of its radial position in the gear ring operation process, the cannelure medial surface contacts with the taper contraction front with higher fineness with wearing layer on the lateral surface, frictional force is little, and it is reliable and stable to turn round.

Description of drawings

Fig. 1 is known gear ring and deep bid structural representation;

Fig. 2 is embodiment gear ring and deep bid structural representation;

Fig. 3 is the partial enlarged drawing of reference column and cannelure among Fig. 2;

The specific embodiment

On April 9th, 2003, the Chinese patent CN2543968Y of bulletin disclosed a kind of circular disc knitting machine transmission device, believe that reading over this patent documentation helps better to understand the utility model, simultaneously, constitute the circular disc knitting machine part but will not repeat as known technology embodiment with the irrelevant structure of the present utility model content.

With reference to figure 2, Fig. 3, embodiment discloses a kind of novel circular disc knitting machine, comprise deep bid 5, be located at the gear ring 6 and the driving mechanism thereof of deep bid 5 tops, described deep bid 5 upper surfaces along the circumferential direction are evenly equipped with four reference columns 7, described each reference column 7 is fixedly arranged on the deep bid 5 by bolt 8 respectively, the upper end of each reference column 7 is provided with the taper contraction front, described gear ring 6 radial outside lower surfaces offer and the suitable cannelure 61 of described taper contraction front, radial direction along gear ring 6, described cannelure 61 medial surfaces and lateral surface are respectively equipped with one deck wearing layer 62, thereby described taper contraction front makes cannelure 61 along the circumferential direction be subjected to uniform radial load by wearing layer 62, under the driving of driving mechanism, stable during gear ring 6 rotation, vibrate for a short time, it can not produce eccentric wear with vertical contact-making surface between the deep bid 5.

In the foregoing description, the quantity of described reference column can be five, six, eight even more, and it can realize the purpose of this utility model equally.

Claims

1, a kind of novel circular disc knitting machine, comprise deep bid and be located at the gear ring of deep bid top, it is characterized in that: described deep bid upper surface along the circumferential direction is evenly equipped with at least four reference columns, described each reference column upper end is provided with the taper contraction front, described gear ring lower surface offers and the suitable cannelure of described taper contraction front, along the radial direction of gear ring, described cannelure medial surface and lateral surface are respectively equipped with one deck wearing layer.
