Description of the invention (/) The present invention relates to a sewing M, which has at least one needle bar and a calendar bar, and the two bars are supported in a dice and driven to move up and down. The published German patent case D E 195 1 3 4 0 6 shows a sewing machine in which the needle bar is sealed to the casing by a sealing element. US Patent No. 4,545,312 discloses a tuft planting machine. Among them, the rod is set to seal the body through a polishing seal, and the O-ring is also used as a sealing element, but they can only be used in slow-speed rotary machines. Generation sewing machines operating at K6000 and more stitches per minute, due to the generated frictional force, the 0 ring will be greatly abraded, so that it can only remain sealed for a short period of time. In this way, the oil * added to the rotating or vibrating member for dripping in the casing will drop Juqin A from the casing when the sewing machine is stopped because they flow on the rod. Not only will the oil be lost, it will also cause the sewing material to become contaminated. Therefore, as the number of stitches in a modern generation of sewing machines increases, the sealing element must not be used. In order to make a seal, the top end of the metal guide shaft sleeve is designed as a sharp (please read the precautions on the back before filling this page). The property bureau employee consumer cooperative printed the edge 2 2 sets of shafts S, P, etc. in the ED to benefit their expertise.

Valve stem seals are stalk seals designed for maximum load and temperature. It is generally made of a gold The ring is formed by a reinforced ring. The ring is hardened by vulcanization. The sealing lip is composed of an elastomeric part containing a film and a spirally stretched strong spring ring. The scraping effect of this valve stem seal is in In dynamic operation, it is mainly achieved by the radial force acting on the valve stem or the contact angle K between the valve shaft and the sealing lip on the side of the slip medium and the action distance of the strong spring. Since the seal 1 itself expands K and The component caused by the expansion of the helical tension spring placed on it exerts radial force. The main disadvantage of a valve stem seal is that * it allows oil to pass through, and the method of passage varies depending on the construction of the internal combustion engine. By the relevant structural design, Change the sealing lip area to achieve the oil passing method 'in a certain -4- This paper size applies the national standard (CNS) A4 (210 X 297 mm) (Please read the precautions on the back before filling in (This page) A7 ____B7_ 5 In the limit of the invention (), this can be achieved by the change of the positive spring distance and the love of the contact angle on the side of the sliding medium. In order to prevent the valve or valve stem from getting stuck in the cylinder head of the internal combustion engine, so Some degree of oil penetration is absolutely required. The valve shaft seal is designed so that it facilitates the movement of the oil in one direction. The oil in the cylinder head (which is probably passed by the valve shaft seal) is harmless in the internal combustion engine Because it will burn out in the combustion chamber. Unexpectedly, the fact shows that the valve shaft seal A originally designed for internal combustion engines is used between the housing of the sewing machine and the movable needle to hold the cloth stalk. When making seals, the inertia is not at all like the common sense of internal combustion, and the lubricants encountered are very small, so this insignificant amount of slippage can be used when the sewing machine is operating or when it is not working. Μ Ignored. In a test operation with a crankshaft rotating speed of 7000 rpm and a net operating time of 7000 hours, no oil leakage was found on the needle bar. Although there is no oil to wipe off from the needle bar, But there is still a sufficient layer of lubrication Membrane to prevent erosion between the supporting bushing and the rod (sliding speed of about 6.7 to 600 / s).----- * — — — — — ^ -— — 11 ---- < Please first (Notes on the back of Μreading #write this page again) The consumer cooperation of the Intellectual Property Bureau of the Ministry of Economy The action does not match the needle of the handle as it has been driven so far.

Description of the invention (f) (Please read the note on the back first to write this page) (They are less resistant to abrasion than high-strength lanthanum, so these are not used in conventional techniques material). The use of lighter materials can also greatly reduce the inertial force of higher measurement levels, so not only can the murmur be minimized at high speeds, but also the motor drive power can be reduced, or the same can be maintained at the same power. The driving torque is correspondingly increased. Slight wear on the needle bar, cloth presser bar, and guide bushing over time • Increased oil throughput (larger bearing clearance). With valve shaft seals, a situation where the bearing clearance due to wear increases will not affect the oil throughput. This in turn allows the manufacturing margin (allowable error) to be larger κ, so the manufacturing cost can be lower. In addition, with the stem seal, the sealing position can be set above the bearing position in the case 骽. In this way, it is no longer necessary to send oil back to the inside of the housing with high construction costs (in conventional technology, this oil will pass through the bearing and drip down onto the sewing reel). Printed by Shelley Consumer Cooperative, Intellectual Property Bureau, Ministry of Economic Affairs After removing the needle stalk or cloth rod, this valve stem seal can be easily removed. If the valve stem seal is too worn during operation, it can be replaced quickly and cheaply. This downtime and the resulting reduction in production is small. As long as the support sleeve is changed in structure, the stent in operation can be modified or retrofitted without any problems.

The front end of the arm shaft (2) is provided with at least a needle bar (S) and a cloth pressing stalk (6), which is driven by a crank drive (9) to move up and down. The rod (5) (6) runs through the support shaft sleeve (3) (3a) fixed in the lower part of the casing (1) and passes out of the dice body (1). The needle (4) M is set in the conventional manner on the lower end of the metering stalk (5), and the cloth presser foot (7) is set in the conventional manner on the lower end of the cloth presser lever (6).
