Abstract
The invention discloses a disk knitter gear structure which is an integrated structure processed by nylon materials. The gear comprises a spoke, an outer gear ring and a lug loop for assembling, wherein the outer gear ring and the lug loop are arranged at the circumferential side of the spoke; the lug loop is arranged at one side of the outer gear ring; the outer gear ring is combined by an upper gear ring and a lower gear ring; the upper gear ring and the lower gear ring are separated by an annular groove; the shifting teeth of the upper gear ring and the lower gear ring are identical; and each shifting tooth of the two gear rings extends to the inner end and the outer end of the top surface of each gear ring along the axial direction of the gear. The disk knitter gear of the invention is processed and formed by nylon materials; because nylon is one of plastic materials, when the disk knitter gear is meshed with peripheral small gears, the meshing process has low noise and nearly has no noise; and the disk knitter gear has the advantages of strong wear resistance, noise absorption, shock reduction, convenient maintenance, low production cost and the like.
Description
Technical field
The present invention discloses a kind of disk knitter gear structure, divides by International Patent Classification (IPC) (IPC) to belong to loom gear manufacturing technology field, specifically relates to a kind of upward dish gear that is applied on the circular disc knitting machine.
Background technique
Circular disc knitting machine is the knitting industry a kind of loom that arrives commonly used, and loom parts are in the market generally formed by metal solder or casting, because the associated components of loom is a member easy to wear, in case damage not quick detachable maintenance.
The dish gear of going up of disk loom is driven by live axle that is arranged at its side and small gear, and then drives disc spins on the loom through transmission shaft, and syringe is rotated with respect to cam mechanism, realizes knitting function.Existing upward dish gear is to be processed by plain cast iron or iron and steel material quality; The small gear of its when running and side radially contacts contact face only has about three centimeters; Because last dish gear is an iron and steel material quality; Like quality is not that the very good dish service life of gear of going up has only some months, and the dish gear uses will wear and tear in 2 years to 3 years and breaks down on the normal steel.More renew go up the dish gear time because gear weight is big and the mounting structure relative complex, that repair and replacement are got up is time-consuming, effort, cost are high.
The existing dish gear of going up is to adopt the traditional steel gear process to form, casting-machined into polishing-spray rust proof paint-opening (tooth), and a gear wants recruitment about 8 hours.
On total, on coil the iron and steel gear deficiency: loud during rotation with the pinion of its side, complex manufacturing, the process-cycle grows up to this height, the inconvenience of denticle Heavy Weight is changed and is assembled, working life is not high.
The inventor is through studying for a long period of time and test of many times, and is less and be not very high characteristics to driving gear requiring aspect the intensity with respect to the power of last dish gear transmission, creates the improvement structure of dish gear on the knitting machine, so proposition of the present invention is just arranged.
Summary of the invention
To the deficiency of dish gear configurations technology on the existing knitting machine, the invention provides a kind of rational in infrastructure, long service life and disk knitter gear structure easy to maintenance.
For achieving the above object, the present invention realizes through following technological scheme:
A kind of disk knitter gear structure; Be the integrated structure that processes by nylon material, the boss ring that described gear comprises spoke, external toothing and is used to assemble, wherein; All sides of spoke are external toothing and boss ring; The boss ring is arranged at a side of external toothing, and said external toothing is to be combined as a whole by upper and lower gear ring, is separated by an annular groove between the upper and lower gear ring; Upper and lower gear ring to stir tooth identical, above-mentioned two gear rings respectively stir tooth along gear shaft to the interior outer end that extends to the gear ring end face.
Further, described spoke centre is an axis hole, is used for and transmission shaft assembling, and spoke is a former with holes or from the axis hole width of cloth bar of dispersion shape towards periphery, the outer end of above-mentioned former and width of cloth bar and external toothing and boss ring fix as one.
Further, the annular groove between the described upper and lower gear ring is wide to be 1.5～2.5mm (millimeter), and the width of upper and lower gear ring is 2.5～3.5cm (centimetre).
A kind of disk knitter gear structure by MC nylon material centrifugal casting moulding, and forms finished product in upper and lower gear ring surface tooth punching, and described spun casting operation is specific as follows:
(1), mould and die preheating is 165 ℃-175 ℃;
(2), with caprolactam, White Mineral Oil, molybdenum disulfide Hybrid Heating to 140 ℃, and dissolve and pour in the reaction kettle;
(3), reaction kettle keeps 140 ℃ of temperature, degree of vacuum to carry out vacuum dehydration at 760mmHg;
(4), keep vacuum to add sodium hydroxide, continue vacuum dehydration, 30 minutes, judge that moisture purifies;
(5), keep vacuum to add TDI-toluene two different blue or green acid esters stirring down material is poured in the mould in the good step of preheating (1), die temperature keeps getting final product in 30-40 minute the demoulding at 170 ℃.
Further, described caprolactam: sodium hydroxide: TDI-toluene two different blue or green acid esters are 1000: 1-1.2: 3-4.
Disk knitter gear of the present invention adopts nylon material to be processed to form, because that nylon belongs to plastic material is a kind of, noise is little during with peripheral pinion, near noiseless.Because the dish gear has upper and lower gear ring on the nylon of the present invention; When wearing and tearing can be dismantled fully during one of them gear ring and used another gear ring and work on; The concrete replacing operated as follows: become mechanism movable up and down to small gear the design of last dish gear periphery, the small gear central shaft is provided with steel ring, can move up and down the small gear of its top like this; Thereby selection cooperates with upper ring gear or lower ring gear; Make things convenient between nylon gear and to change damaged gear, reach the effect of replacing and work on, match but above-mentioned movably pinion shaft structure is convenient to big disk during assembling and setting simultaneously.
The dish gear has following advantage on the nylon of the present invention:
1, the dish gear has strong, the sound-absorbing damping of wear resistance on the nylon, self-lubrication, and production technology is simple, is convenient to advantages such as batch process;
2, the dish Gear Processing cycle is short on the nylon, cost is low and have environmental protection, the light corrosion resistant of body body, simultaneously long service life.
