Abstract
The utility model relates to a main shaft driving apparatus for a composite type high speed needling machine with minor axis used for wide geotextile production. The utility model is composed of a main shaft, a bearing seat, a belt pulley, an eccentric wheel, a left and a right connecting rods, a left and a right guide bars, etc. The utility model is characterized in that a shaft joint and a balance compensation mechanism are additionally arranged on the main shaft, and has the advantages of convenient manufacture, good rigidity and precision of the main shaft, smooth operation on the job, less noise, long service life, automatic compensation correction of radial bouncing, axial float or concentricity windage generated between shaft groups through the balancing compensation mechanism.
Description
The utility model relates to a kind of minor axis combined high-speed needing machine spindle gearing that wealthy width of cloth geotextiles is produced that is used for.
Traditional high-speed needling machine spindle gearing is a major axis monoblock type eccentric block structure, the major defect of this structure is: 1. processing difficulties, the inaccessible designing requirement of position of related features of the positioning spline of being opened on the form and position tolerance of major axis and the axle, the above major axis of 5.3m particularly, processing and manufacturing be difficulty especially.2. on the major axis of traditional structure a plurality of eccentric wheels, connecting rod, guide rod and needle beam must be set, and the highs and lows during real work is not at grade, each moving point and fixing point load uniformity are poor during acupuncture, variable is very big, cause needle beam bending or main shaft to be twisted and warped easily, make the complete machine cisco unity malfunction, production efficiency descends, until damage.3. rotate synchronously around main shaft when working owing to the weighting block of traditional structure, to reach balance, and the gravity station of weighting block not only restive location of when assembling, and the centrifugal force when weighting block rotates at a high speed can make equipment produce that bigger vibration, operating frequency can not improve, noise is big, operating mode is unstable.
The purpose of this utility model is the design shortcoming that overcomes above-mentioned prior art, provide a kind of convenient processing and manufacture, running steadily, circular runout and axial float are little, connecting rod, guide rod traverse unanimity, the minor axis combined high-speed needing machine spindle gearing of rigidity and good stability.
Goal of the invention of the present utility model is realized by following technical scheme:
The utility model comprises the main shaft 3 that is bearing on bearing block 1a, 1b, the 1c, the belt pulley 2 of main shaft 3 one ends, be positioned at eccentric wheel 4, left connecting rod 5, right connecting rod 5 ' on the main shaft 3, left guide rod 6, the right guide rod 6 ' that is connected with the other end of this left and right sides connecting rod respectively, the other end that it is characterized by main shaft 3 is provided with shaft coupling 19, also is provided with balanced compensated mechanism on the main shaft 3.
Said balanced compensated mechanism is made up of the inside connecting rod 20,20 ' that is positioned at main shaft 3 middle parts in the utility model, and inside connecting rod 20,20 ' the other end are connected with along the balance weight 12 of guide pillar 13,13 ' motion.Said shaft coupling 19 is a crown gear coupling.
Main shaft one end of the present utility model is provided with shaft coupling, can be with the minor axis fabricated structure of major axis architecture advances for there being a plurality of minor axises to link to each other of prior art.And shaft coupling adopts crown gear coupling, and on main shaft, be provided with connecting rod, the balanced compensated mechanism that moves along guide pillar, so main shaft of the present utility model is convenient processing and manufacture not only, rigidity and precision are easy to guarantee, and when work running steadily, and noise is little, even produce circular runout, axial float or coaxiality deviation between the axle group, also can compensate correction automatically, can improve the operating efficiency and the service life of needing machine effectively by balanced compensated mechanism.
Accompanying drawing 1 is the utility model embodiment and structural representation after the high-speed needling machine needle beam is connected.
Accompanying drawing 2 is the A-A cutaway view of Fig. 1.
Among the figure: 1a, 1b, 1c-bearing block, 2-belt pulley, 3-main shaft, 4-eccentric wheel, 5-left side connecting rod, 5 '-right connecting rod, 6-left side guide rod, 6 '-right guide rod, 7-sliding shaft sleeve, 8-guide pin bushing, 9-oil strain cover, 10-oil sealing end cap, 11-pressing plate, 12-balance weight, 13,13 '-guide pillar, 14-sliding sleeve, 15-fixed cover, 16-bearing pin, 17-needle beam, 18-needle plate, 19-shaft coupling, 20,20 '-inside connecting rod.
Further describe the utility model below in conjunction with drawings and Examples.
Referring to accompanying drawing 1, one end of main shaft 3 is fixedlyed connected with belt pulley 2, with transferring power, the other end is provided with shaft coupling 19, main shaft 3 is bearing on bearing block 1a, 1b, the 1c, and this bearing block is separately fixed on the frame and (does not draw among the frame figure), and an end of left connecting rod 5, right connecting rod 5 ' is connected with main shaft 3 respectively, the other end is connected with left guide rod 6, right guide rod 6 ' respectively, and the connecting portion of left and right guide rod and main shaft 3 all has eccentric wheel 4.The other end of left side guide rod 6, right guide rod 6 ' is fixedlyed connected with the needle beam 17 on needle plate 18 tops through the sliding bearing 7 that is fixed on the frame.Balanced compensated mechanism on the main shaft 3 is arranged between left connecting rod 5 and the right connecting rod 5 ', form by the inside connecting rod 20,20 ' that is located at bearing block 1c both sides, inside connecting rod 20,20 ' the other end are connected with balance weight 12, main shaft 3 rotating band dynamic balancing pieces 12 move up and down, its direction of motion is opposite with the direction of motion of needle beam, makes the high-speed needling machine operating mode steady.
