Abstract
The utility model discloses a kind of reciprocating drive device, it includes eccentric shaft, fixing bearing and connecting rod, the eccentric shaft is arranged in fixing bearing, the eccentric shaft misaligned first axle and second axle including diameter parallel, the first axle is connected with motor, and connecting rod one end fits are in the second axle；The connecting rod other end is additionally provided with universal joint, and described universal joint one end is welded with connecting rod, threaded connection or flange are connected, and the universal joint other end connects for other devices.The utility model using universal joint absorb traditional eccentric shaft produce can be brought while reciprocating motion it is miscellaneous to vibration, so as to so that transmission device can be moved back and forth only in one direction, effectively overcome the deficiency of traditional eccentric shaft.
Description
Technical field
It the utility model is related to a kind of reciprocating drive device.
Background technology
Reciprocator is widely used in plant equipment, is moved back and forth typically by by the rotation of the devices such as motor
Turn conversion of motion, the device of conversion is mainly eccentric wheel, while the device for also there are other forms can realize this function.
Eccentric wheel is because its is simple in construction, manufacturing cost is low and is widely used.However, convert rotational motion is being reciprocal by eccentric wheel
Because the particularity of structure often brings the fortune by a small margin on another direction (being different from vibration-direction) during motion
Dynamic, this may bring bad effect in some special dimensions；How existing eccentric wheel structure to be improved and is eliminated
Its experiencing small oscillating movements in other directions (referring to non-reciprocating direction) is that the application needs to solve the problems, such as.
Utility model content
The purpose of this utility model be to provide it is a kind of it is simple in construction, without the miscellaneous reciprocating drive device to vibration.
To reach above-mentioned purpose, scheme is used by the utility model：
A kind of reciprocating drive device, it includes eccentric shaft, fixing bearing and connecting rod, and the eccentric shaft is arranged at solid
In dead axle is held, the eccentric shaft misaligned first axle and the second axle, the first axle and motor including diameter parallel
It is connected, connecting rod one end fits are in the second axle；The connecting rod other end is additionally provided with universal joint, and described universal joint one end is with being connected
Bar welding, threaded connection or flange connection, the universal joint other end connect for other devices.
Universal joint is generally used in transmit torque between two rotary shafts, and present inventor is creatively used
In reciprocating mechanism, it is set to eliminate the miscellaneous to motion of traditional eccentric shaft while reciprocating motion is produced, so as to keep away
Exempt from the vibration also having outside reciprocating motion.And the transmission structures are simple, easily manufactured.
Preferably, second axle is arranged in the middle part of first axle, and the fixing bearing has two, and second axle is arranged at
Between two fixing bearings.Second axle is arranged to stability when can increase device rotation between two fixing bearings.
Preferably, the mode that the universal joint is connected with other devices is mode connects for screw, is connected together, welds.
Preferably, 5 centimetres are deviateed between the axis of the first axle of the eccentric shaft and the second axle.For most equipment
For, 5 centimetres are a preferably selections, naturally it is also possible to are adjusted again as needed.
Preferably, the fixing bearing is provided with rubber ring.Rubber ring can absorb certain vibration.
The utility model using universal joint absorb traditional eccentric shaft produce can be brought while reciprocating motion it is miscellaneous to shaking
It is dynamic, so as to so that transmission device can be moved back and forth only in one direction, effectively overcome the deficiency of traditional eccentric shaft.

Fig. 4 is gimbal structure schematic diagram.
Wherein, 1, eccentric shaft, 2, connecting rod, 11, first axle, the 12, second axle, 3, universal joint.
Embodiment
Structure of the present utility model is specifically described below in conjunction with the accompanying drawings, so that those skilled in the art can be more
The technical solution of the utility model is expressly understood, is clearly limited so as to be made to the scope of protection of the utility model.
A kind of reciprocating drive device, it is made up of eccentric shaft 1, fixing bearing and connecting rod 2, and the eccentric shaft 1 is set
It is placed in fixing bearing, it can be rotated automatically in fixing bearing；The eccentric shaft 1 include diameter parallel and misaligned first
The axle 12 of axle 11 and second, 5 centimetres are deviateed between the axis of the axle 12 of first axle 11 and second of eccentric shaft 1, certain He of first axle 11
The distance deviateed between the axis of second axle 12 is also satisfying to be set as other values as needed；The first axle 11 and motor phase
Even, so that eccentric shaft 1 can rotate under the drive of motor；The one end fits of connecting rod 2 are matched somebody with somebody in the second axle 12 by bearing
Close, so that connecting rod 2 can move back and forth (the motion of approximate ellipsoidal in the presence of the second axle 12 when eccentric shaft 1 rotates
Track, reciprocating motion can be produced)；The other end of connecting rod 2 is additionally provided with universal joint 3, described one end of universal joint 3 and connecting rod
Welding, threaded connection or flange connection, the other end of universal joint 3 connect for other devices；Universal joint 3 is in the presence of connecting rod 2
Motion, at the same can eliminate it is miscellaneous to motion, to provide simple unidirectional reciprocating motion to other devices.
The mode that the universal joint 3 is connected with other devices is mode connects for screw, is connected together, welds.
In some preferred embodiments, second axle 12 is arranged at the middle part of first axle 1, and the fixing bearing has two,
Second axle 12 is arranged between two fixing bearings；The fixing bearing is provided with rubber ring.I.e. first axle has two parts, together
The heart is set, between the first axle of the second shaft position two (set-up mode of " axle of first axle-the second-first axle ")；Coordinate two fixations
Bearing can improve stability during eccentric shaft rotation, and rubber ring can then eliminate and absorb certain vibration, it is not passed
It is delivered on pedestal or lathe.
The ground illustrated is needed, the set-up mode above with respect to the second axle is only exemplary explanation, any other mode
Diameter parallel and misaligned setting is also possible to the purpose of this utility model.
