SU63404A1 - The mechanism of landing carriage selfaktor - Google Patents

Description

The landing mechanism is used for a small supply of the carriage of the selfactor to the bar during the twisting, in order to reduce the breakage of the threads on the carbonaceous selfactors.

The known carriage landing mechanisms, equipped with a screw, which is driven from the shaft of the spun drums, are complex in design, often disorganized, and require very skilled supervision.

The proposed mechanism, the purpose of which is to eliminate the noted shortcomings, has the distinctive feature that the carriage screw is equipped with a spring-loaded nut with cams at the end, the scene is tightened with the cams of the spring-loaded sleeve, which is installed movably on the key of the middle frame of the agricultural machine.

In FIG. 1 depicts a side view, partially in section, of a part of the mechanism mounted on the carriage of the selfactor; FIG. 2 is a side view of a part of the mechanism mounted on the middle frame of the selfactor; FIG. 3 is a cross-section of the mechanism according to A-B in FIG. one.

A screw 13, a worm gear 12, a roller 10 and gears 8 and 9 are set in motion from the shaft of the spunted drums by screw 13. The bearing 14 is bolted to the middle frame of the machine and supplied with a key. In the bearing 14 inserted sleeve 15 with a chamfer, which includes the key 6 of the bearing. By key 6, sleeve 15 may be mixed along its axis. The sleeve on the left (according to the drawing) has a bead with cams 7 corresponding to the cams 11 of the nut 3. The spring 16, mounted on the sleeve 15, serves to create an elastic stopping of the carriage 1 at the end of its withdrawal, which eliminates the harmful deflection of the ends of the carriage, and, consequently, breaks nptey arising from deflections. The sleeve 15 is fixed in the bearing ring 17.

At the end of the carriage waste, the cams 11 of the nut 3 and the cams 7 of the sleeve 15 are engaged. The screw 2 is inserted at this time, and the nut 3, the rotation of which is prevented by the keys 4, is unscrewed along the screw 2 and thereby moves the carriage 1 to the beam. The advancement of the carriage continues for a short period of time after turning the "selfactor control lock". When landing spring about

curls, i.e., it stores energy in itself. When the carriage returns, when the cams 11 and 7 are disengaged, the spring 5 rotates the nut 3 in the direction of rotation of the screw 2 and returns it to its original position.

Subject invention

The mechanism for planting the carriage of a selfaktor with a screw driven from the shaft of the spindle drums, characterized in that a spring-loaded screwdriver 2, a nut 3 with cams on the end, engaging with the cogs on the spring bushing sleeve 15, is used to feed the carriage , movably on the key installed on the middle frame of the machine.
