Abstract
A kind of driving structure of oscillating shuttle of sewing machine is the utility model is related to, including the shuttle axle sleeve and passive tooth being co-axially located on shuttle axle；The fan tooth being meshed with passive tooth, fan tooth is arranged on swinging axle and is structure as a whole, swinging axle be arranged in parallel with shuttle axle, swing arm is also set up on swinging axle, swing arm and a rod hinge connection, described connecting rod is connected with a capacity eccentric bearing outer rim, and the overcoat of connecting rod and capacity eccentric bearing is structure as a whole, capacity eccentric bearing and driving axis connection, drive shaft be arranged in parallel with shuttle axle, the utility model is driven using capacity eccentric bearing, connecting rod and capacity eccentric bearing overcoat integrative-structure, swinging axle and fan tooth are also to be integrally formed, the utility model only has and needs to be hinged between connecting rod and swinging axle, as long as other parts are directly fixed, with working stability easy to assembly, so that shuttle also is adapted for using on high speed sewing machine.
Description
Technical field
Sewing machine technique is the utility model is related to, specifically a kind of driving structure of oscillating shuttle of sewing machine.
Background technology
If notification number is that CN204237993U discloses a kind of shuttle crank connecting link shuttle drive mechanism, including driving electricity
Machine, in the output end of the motor with bevel gear is unified, the bevel gear connects one first shuttle rotating shaft, described
The other end of first shuttle rotating shaft is provided with shuttle actively fork, and the shuttle actively fork connects a shuttle connecting rod, and the shuttle connects
The other end connection shuttle swing rod of bar, a shuttle power transmission shaft is provided with the shuttle swing rod, is set on the shuttle power transmission shaft
There is the driven sector gear of a shuttle, the driven quadrant drive of shuttle connects a shuttle travelling gear, the shuttle transmission
Gear is fixed in the second shuttle rotating shaft, and shuttle component is provided with the end of the second shuttle travelling gear；This tradition pendulum
Connected between each part of drive mechanism of shuttle excessively, easily occur local loosening when moving one section between part, easily go out after loosening
Existing abnormal sound, stability is not good enough, therefore is only suitable for low speed sewing machine.
Utility model content
The purpose of this utility model is to provide a kind of driving structure of oscillating shuttle of sewing machine, driven using capacity eccentric bearing, is connected
Bar and capacity eccentric bearing overcoat integrative-structure, swinging axle and fan tooth are also to be integrally formed, and the utility model only has connecting rod and swinging axle
Between need to be hinged, as long as other parts are directly fixed, there is the characteristics of working stability easy to assembly so that shuttle is also fitted
Conjunction uses on high speed sewing machine.
Following technical scheme is used to achieve the above object：
A kind of driving structure of oscillating shuttle of sewing machine, it is characterised in that：Including the shuttle axle sleeve that is co-axially located on shuttle axle and
Passive tooth；The fan tooth being meshed with passive tooth, fan tooth are arranged on swinging axle and are structure as a whole, and swinging axle is parallel with shuttle axle to be set
Put, swing arm, swing arm and a rod hinge connection are also set up on swinging axle, described connecting rod is connected with a capacity eccentric bearing outer rim, partially
Mandrel is held to be arranged in parallel with driving axis connection, drive shaft with shuttle axle.
Described connecting rod and the overcoat of capacity eccentric bearing are structure as a whole.
Described capacity eccentric bearing and swinging axle is distributed in the both sides below shuttle axle, and swing arm is located at the outside of swinging axle, fans tooth
Positioned at the inner side of swinging axle.
The utility model substitutes conventional cam and swing rod using capacity eccentric bearing, while by the outer of connecting rod and capacity eccentric bearing
Set is arranged to integrative-structure, so needs attachment to set an entirety originally equivalent to by cam, swing rod and connecting rod three,
And fan tooth and swinging axle are also configured as integrative-structure, directly drive swinging axle to swing by capacity eccentric bearing, centre only connects
Using being articulated and connected between bar and swing arm, noise is low when capacity eccentric bearing rotates at a high speed, and stability is good, and this is to realize that shuttle can be at a high speed
The premise of operating, it can be also adapted to thereby using shuttle on high speed sewing machine.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model（One）；
Fig. 2 is structural representation of the present utility model（Two）；
Fig. 3 is structural representation of the present utility model（Three）.
Embodiment
As Figure 1-3, a kind of driving structure of oscillating shuttle of sewing machine, it is characterised in that：Including being co-axially located on shuttle axle 1
Shuttle axle sleeve 2 and passive tooth 3；The fan tooth 4 being meshed with passive tooth 3, fan tooth 4 are arranged on swinging axle 5 and are structure as a whole,
Swinging axle 5 is be arranged in parallel with shuttle axle 1, and swing arm 6 is also set up on swinging axle 5, and the connecting rod 7 of swing arm 6 and one is be hinged, described connecting rod
7 are connected with the outer rim of a capacity eccentric bearing 8, and the overcoat 81 of described connecting rod 7 and capacity eccentric bearing 8 is structure as a whole, and capacity eccentric bearing 8 is with driving
Moving axis connects, and drive shaft be arranged in parallel with shuttle axle 1, and described capacity eccentric bearing 8 and swinging axle 5 are distributed in the both sides below shuttle axle 1.
The utility model substitutes conventional cam and swing rod using capacity eccentric bearing, while by the outer of connecting rod and capacity eccentric bearing
Set is arranged to integrative-structure, so needs attachment to set an entirety originally equivalent to by cam, swing rod and connecting rod three,
And fan tooth and swinging axle are also configured as integrative-structure, directly drive swinging axle to swing by capacity eccentric bearing, centre only connects
Using being articulated and connected between bar and swing arm, noise is low when capacity eccentric bearing rotates at a high speed, and stability is good, simultaneously because capacity eccentric bearing and
Swinging axle is distributed in the both sides below shuttle axle, so fans tooth position in the inner side of swinging axle, and swing arm is located at the outside of swinging axle, swings
Axle in the case where capacity eccentric bearing drives at a high speed, cancel out each other, and reduces the stress of swing arm, can also play certain drop by the active force of both sides
Make an uproar effect；Swing arm carries out realizing that shuttle can run at high speed, and can be also adapted to thereby using shuttle on high speed sewing machine.
Claims (2)
- A kind of 1. driving structure of oscillating shuttle of sewing machine, it is characterised in that：Including the shuttle axle sleeve that is co-axially located on shuttle axle and by Moving teeth；The fan tooth being meshed with passive tooth, fan tooth are arranged on swinging axle and are structure as a whole, and swinging axle is parallel with shuttle axle to be set To put, swing arm, swing arm and a rod hinge connection are also set up on swinging axle, described connecting rod is connected with a capacity eccentric bearing outer rim, and And the overcoat of connecting rod and capacity eccentric bearing is structure as a whole, capacity eccentric bearing be arranged in parallel with driving axis connection, drive shaft with shuttle axle.
- A kind of 2. driving structure of oscillating shuttle of sewing machine as claimed in claim 1, it is characterised in that：Described capacity eccentric bearing and pendulum Moving axis is distributed in the both sides below shuttle axle, and swing arm is located at the outside of swinging axle, and fan tooth position is in the inner side of swinging axle.
