Detailed description of the invention
The core of the present invention is for providing a kind of unidirectional rotation joint fork, and this unidirectional rotation joint fork uses spline structure design to realize between centers connection, is designed to realize single-direction transmission by its special structure, thus avoids repercussion transmission to cause the problem of device damage to occur.
In order to make those skilled in the art be more fully understood that technical scheme, the present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Refer to Fig. 1 to Fig. 3, wherein, Fig. 1 is the structural representation of unidirectional rotation joint fork in an embodiment of the present invention；Fig. 2 is the sectional view of unidirectional rotation joint fork in an embodiment of the present invention；Fig. 3 is the sectional view of joint fork main body in an embodiment of the present invention.
The invention provides a kind of unidirectional rotation joint fork, connection for axle head, including: joint fork main body 1, one end of joint fork main body 1 is joint fork, the other end of joint fork main body 1 is spline installing hole 2, uniformly offering groove on described spline installing hole 2, described groove is the groove that unidirectional radius of curvature is gradually increased；Splined connection 3, one end of splined connection 3 is inserted in spline installing hole 2, and this end is provided with abut unidirectional piece 4 unidirectional with spline installing hole 2, and the bottom of unidirectional piece 4 is provided with spring, and the other end of splined connection 3 is provided with Quick-connection pin 5.
Skilled person will appreciate that, spline structure is uniformly to offer groove structure on the sidewall in hole, in the present invention, this groove structure is the groove that unidirectional radius of curvature is gradually increased, when being connected in spline installing hole 2 for unidirectional piece 4, when rotating forward, blocked by groove, it is achieved rotary spacing, this time fork main body 1 is connected for relatively-stationary with splined connection 3, thus realizes power transmission；Then being gradually increased due to radius of curvature when reversely rotating, unidirectional piece 4 can skid off groove, it is achieved the rotation of splined connection 3, thus lose the effect of transmission.
The present invention is designed to realize single-direction transmission by its special structure, thus avoids repercussion transmission to cause the problem of device damage to occur.
Specifically, the bottom of joint fork is provided with oil nozzle.
Specifically, joint fork offering the installing hole for installing, installing hole connects for universal joint.
Specifically, splined connection is provided with fast joint structure, and fast joint structure can realize splined connection and be connected with the quick of splined shaft.
Refer to single direction rotation in Fig. 4, Fig. 4 an embodiment of the present invention connect fork be installed on the structural representation on agricultural power transmission shaft.
With an optimum embodiment of the present invention, the present invention is carried out detailed structure below to describe.
Joint fork and joint fork main body are by being welded together；And splined connection, nylon bearing, metal collar, unidirectional piece, spring extruding connection under the effect of jump ring, and constitute a metastable relation with joint fork main body；There are jump ring road and unidirectional groove, the unidirectional piece of elastic force by spring in joint fork inner major diameter, withstand in the unidirectional groove of joint fork main body, and main body is also in the groove of splined connection；Quick-connection pin passes through Spring Card in the hole of splined connection；Oil nozzle is by being threaded onto in joint fork.
Operation principle is as follows: during rotating forward, the joint fork being connected with power transmission shaft rotates, owing to joint fork main body and joint fork weld together, joint fork main body is caused to rotate clockwise, owing to unidirectional piece is stuck in the unidirectional groove that joint pitches main body, the most unidirectional piece is all plane with joint fork body contact face simultaneously, cannot relatively rotate, unidirectional piece is forced to rotate the most together, the body of the most unidirectional piece is stuck in the groove of splined connection, cause splined connection to rotate the most together, and splined connection connects below is that workpiece rotates the most together, it is achieved that the function of power transmission.During reversion, the joint fork being connected with power transmission shaft rotates, owing to joint fork main body and joint fork weld together, joint fork main body is caused to rotate counterclockwise, and the most above the groove of joint fork main body is a smooth curve the longest, and the head of unidirectional piece is also a smooth round end, it is easy to produce relative motion, when joint fork main body rotates counterclockwise, the unidirectional piece of long curved groove compressing inward by joint fork main body, extrusion spring is until unidirectional piece falls back in the groove of joint fork joint fork completely, and this process does not allow splined connection rotate together, power is the most just persuaded to be transmitted only in joint fork main body, it is not delivered on splined connection, also it is not delivered on workpiece below, achieve anti-reverse function.When normally working due to agricultural power transmission shaft, the power of transmission is the biggest, the power of 850Nm need to be transmitted as 540rmp, the power of 690Nm need to be transmitted as 1000rpm, for ensureing stability when normally working and life of product, can preferably eliminate power time simultaneously for ensureing reversion, add many improvements.
5 ° of inclined planes that the head increase of unidirectional piece concaves, preferably can be in close contact with the unidirectional groove saving fork main body when rotating forward, transmit power.The most unidirectional piece makes hardness reach HRC40-50 through Overheating Treatment, joint fork joint fork makes hardness reach HRC45-50 with the unidirectional piece of groove contacted also by high-frequency quenching, add shock proof ability, also avoid making unidirectional piece of normal lock return to, in the groove of splined connection, add the service life of product because of deformation simultaneously.
Use the structure of three pieces of unidirectional grooves in unidirectional Kuai Yu six road, increase stability when product reversion is skidded, shorten the distance between adjacent two unidirectional grooves of joint fork main body simultaneously, when unidirectional piece is stuck in when joint is pitched on the internal diameter of main body and the time of rotating forward, can snap into rapidly in the unidirectional groove of joint fork main body, it is to avoid cause because stroke is long impacting ambassador's damage of product.
The top of unidirectional piece uses the disc of R5, smooth curve transition, and the accurate broaching tool disposal molding of this unidirectional groove is used with internal diameter, when inverted on the right of the unidirectional groove of joint fork main body, can preferably force unidirectional piece to move in the groove of joint fork joint fork, make reversion slipping effect more preferably.
The material of nylon bearing is nylon, can preferably force splined connection to be stuck in the inside of joint fork main body by metal collar, and when inverting, it is also possible to reduce rotary resistance.
Increase the structure of oil nozzle, grease can be extruded in the gap of joint fork main body and splined connection at any time by oil nozzle, make return motion more smoothly.
