Abstract
A technology for coating nylon on the surface of splined shaft used in steering drive unit of car includes such steps as pre-treating, dipping in priming paint, heating, coating nylon, cooling in hot water, and cooling in the water at ordinary temp.
Description
Technical field: the present invention relates to the surface treatment of splined shaft, especially surperficial nylon coated technology.
Background technology: the splined shaft assembly is one of vitals of motor turning transmission device, the splined shaft assembly that entrucking is at present used is that splined shaft cooperates with the direct of spline housing, steel part contacts with steel part, fit clearance is big, frictional force is big, automobile in running at high speed or road conditions produce abnormal sound when abominable, shake is strong, direction and sensitivity is not high.
Summary of the invention: for directly cooperating of solving splined shaft and spline housing in the splined shaft assembly that present entrucking uses, frictional force big, automobile is in running at high speed or road conditions not high problem of direction and sensitivity when abominable, the present invention proposes the surperficial nylon coated technology of splined shaft, cold-drawn shaping splined shaft after at first machined being finished is concentrated and is got the raw materials ready, and its technological process is: workpiece preliminary treatment → primer dipping and coating → heating → coating nylon → hot water cooling → normal-temperature water cooling.Adopt the surperficial nylon coated technology of above-mentioned splined shaft, make the splined shaft surface evenly adhere to one deck nylon coating, steel part directly contacts with steel part when avoiding splined shaft to cooperate with spline housing; Described splined shaft with nylon coating applies in the splined shaft assembly of motor turning transmission device, the problem that the frictional force that has solved existing splined shaft and spline housing is big, noise is big, avoided automobile in running at high speed or road conditions not high problem of direction and sensitivity when abominable, improve the service life of splined shaft, spline housing, thereby reduced the maintenance cost of automobile.
The specific embodiment: the cold-drawn shaping splined shaft after machined finished is concentrated and is got the raw materials ready, 1., the workpiece preliminary treatment its technological process is:: the cold-drawn shaping splined shaft after machined is finished carries out blasting treatment, to remove greasy dirt, impurity, the corrosion of surface of the work; 2., primer dipping and coating: dip-coating styrene-butadiene priming paint on surface of the work; 3., heat: the workpiece behind the primer dipping and coating is put into be preheating to 180 ℃-200 ℃ heating furnace, be heated to 330 ℃-335 ℃ then, and came out of the stove after being incubated 15 seconds-17 seconds; 4., coating nylon: the workpiece after will heating and be incubated, immerse immediately in the fluid bed in the nylon powder that suspends by compressed air, at surface of the work coating nylon, apply at twice, the coating time is 3-6 second at every turn; 5., hot water cooling: the workpiece behind the surface applied nylon is cooled off in 70 ℃ of-95 ℃ of hot water storgaes, make the nylon levelling that applies on the workpiece, increase the uniformity that applies; 6., normal-temperature water cooling: at the continuous cooling of normal temperature tank relaying workpiece, the nylon that applies on the surface of the work is solidified, obtain stable nylon coating quality.
Described workpiece preliminary treatment also can be adopted chemical treatment, and promptly degreasing pickling, phosphatization are handled.
It is dry that described compressed air is wanted, and water content is less than 1g/m
3, oil content is less than 0.1g/m
