Abstract
The utility model discloses a transmission shaft bolt, which consists of a transmission head (1) and a rod (2). The center axis of the transmission head (1) and the center axis of the rod (2) are non-collinear. The transmission shaft bolt can be used in an eccentric transmission mechanism and is wide in application range.
Description
Technical field
The utility model relates to a kind of fastening piece, specifically is a kind of transmission shaft bolt.
Background technique
Transmission is one of critical function of present machine, 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.Transmission shaft bolt of the prior art is made up of driving head and bar portion, and described driving head is generally circular bolt head, and the central axis of driving head and cadre's central axis are on same straight line.The transmission shaft bolt of said structure also has the following disadvantages in the using process of reality: because the central axis of driving head and cadre's central axis is on same straight line, this transmission shaft bolt can't be used in the eccentric drive mechanism, so the Applicable scope of this transmission shaft bolt is less.
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 applied widely 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 and bar portion, and the central axis of the central axis of described driving head and bar portion is not on same straight line.
After adopting above structure, the utility model compared with prior art has the following advantages:
The utility model transmission shaft bolt relies on the corresponding aperture interior spline of eccentric hexagon head of bolt and connected piece to press secure fit with carry-over moment by a flat shape key, by tightening the inner thread piece of cooperation, rotate with the transmission shaft bolt during use with the assurance coupling.Because the central axis of described driving head and the central axis of bar portion be not on same straight line, so the utility model transmission shaft bolt can be used in the eccentric drive mechanism.
As improvement, because driving head is equilateral hexagon driving head, therefore can bear the stressed of driving head at a plurality of, so its transmitting torque better.After the long-term use of this transmission shaft bolt, driving head is not easy to wear, and its life-span is longer.
Description of drawings
Fig. 1 is the plan view of the utility model transmission shaft bolt.
Fig. 2 is the left view of the utility model transmission shaft bolt.
Shown in the utility model figure 1, driving head, 2, bar portion.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1 and Figure 2, a kind of transmission shaft bolt of the utility model, described transmission shaft bolt is made up of driving head 1 and bar portion 2, and the central axis of the central axis of described driving head 1 and bar portion 2 is not on same straight line.Described driving head 1 is an inequilateral hexagon driving head.
The utility model transmission shaft bolt relies on the corresponding aperture interior spline of eccentric hexagon head of bolt and connected piece to press secure fit with carry-over moment by a flat shape key, by tightening the inner thread piece of cooperation, rotate with the transmission shaft bolt during use with the assurance coupling.Cooperate inner thread piece not to be subjected to the restriction of single intensity size during use, the transmission requirement that can separate various strength demands, and effectively transmission are 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.
Claims (2)
1. transmission shaft bolt, described transmission shaft bolt is made up of driving head (1) and bar portion (2), it is characterized in that: the central axis of the central axis of described driving head (1) and bar portion (2) is not on same straight line.
2. transmission shaft bolt according to claim 1 is characterized in that: described driving head (1) is an inequilateral hexagon driving head.
