Abstract
The utility model discloses a transmission shaft bolt, which consists of a transmission head (1), a non-threaded rod (2) and a threaded rod (3). Two longitudinal sections which are symmetrical circumferentially are arranged on the periphery of the transmission head (1). The transmission shaft bolt is symmetrical and uniform in stress and can transmit torque well, the transmission head is not easy to be abraded after long-term use of the transmission shaft bolt, so that the transmission shaft bolt has longer service life. Further, as the transmission shaft bolt is uniform in stress, the transmission shaft bolt can bear action of higher torque.
Description
Technical field
The utility model relates to a kind of bolt, specifically is a kind of transmission shaft bolt.
Background technique
Transmission is one of present actual life machine critical function, and the multiple connection kinds of drive such as gear, key, nodal axisn are arranged at present.At present, when actual transmission, be subjected to the influence of space of components on every side of equipment, locomotive, if adopt gear, key, nodal axisn etc. to connect the kind of drive, can interfere the normal use of machinery equipment, make troubles also for simultaneously the assembling of equipment, locomotive, for this reason, people use transmission shaft bolt transmitting torque in a lot of occasions, but transmission shaft bolt of the prior art also has the following disadvantages: even under the situation that nut and bolt screw, the transmission shaft bolt still rotates in the driving component upper shaft hole in the link rotating process easily, well transmitting torque.
The model utility content
The technical problems to be solved in the utility model is, overcomes the defective of above prior art, and a kind of transmission shaft bolt of effectively transmitting torque is provided.
The technical solution of the utility model is, a kind of transmission shaft bolt is provided, and described transmission shaft bolt is made up of driving head, polished rod and threaded stem, and the cylindrical of described driving head is provided with two longitudinal sections along the circumference symmetry.
After adopting above structure, the utility model compared with prior art has the following advantages:
The cylindrical of the driving head of the utility model transmission shaft bolt is provided with two longitudinal sections along the circumference symmetry, its sectional shape is identical with the cross section of cydariform, its regular shape, therefore driving head is when being subjected to twisting force, two faces of two indentation, there of driving head are all stressed, thereby the stressed symmetry of driving head, it is stressed evenly, and it is transmitting torque well.Therefore after the long-term use of this transmission shaft bolt, driving head is not easy to wear, and its life-span is longer.Because this transmission shaft is bolt strained evenly, therefore can bear the effect of big torsion.
As improvement, the central axis of described driving head, the central axis of polished rod, the central axis of threaded stem is on same straight line.Therefore, the shape of the transmission shaft bolt of this kind shape is rule more, and is stressed more even, the effect that can bear bigger torsion.
Description of drawings
Fig. 1 is the plan view of the utility model transmission shaft bolt.
Fig. 2 is the plan view of the utility model transmission shaft bolt.
Fig. 3 is the left view of the utility model transmission shaft bolt.
Shown in the utility model figure 1, driving head, 2, polished rod, 3, threaded stem.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As Fig. 1, Fig. 2, shown in Figure 3, a kind of transmission shaft bolt, described transmission shaft bolt is made up of driving head 1, polished rod 2 and threaded stem 3, and the cylindrical of described driving head 1 is provided with two longitudinal sections along the circumference symmetry.We can say that also the sectional shape of described driving head 1 is a cydariform, promptly the cross section of driving head 1 is identical with the cross section of cydariform, and the sectional shape that can also say driving head 1 cuts geometrical shape behind the dome of center line both sides for the center line symmetry with circle.
The central axis of the central axis of described driving head 1, polished rod 2, the central axis of threaded stem 3 is on same straight line.The center of center, threaded stem 3 that is center, the polished rod 2 of driving head 1 is on same straight line.
This transmission shaft bolt relies on the drum type driving head to cooperate carry-over moment with the corresponding drum type transmission counter sink card jail of coupling, cooperate inner thread piece not to be subjected to the restriction of single intensity size during use, can separate the transmission requirement of various strength demands, and effectively transmission, for daily life is provided convenience.This transmission shaft bolt light rod surface requirements precision height, with coupled closely cooperate.The utility model transmission shaft bolt is easy to process, and it adopts hot rammer processing method to be made.
Below only be described, but can not be interpreted as it is restriction claim with regard to most preferred embodiment of the present utility model.The utility model is not limited only to above embodiment, and its concrete structure allows variation.In every case the various variations of being done in the protection domain of the utility model independent claims are all in protection domain of the present utility model.
