Abstract

The utility relates to a transmission shaft capable of transferring the torque of a speed changer to a driving axle, in particular to a novel transmission shaft. The transmission shaft comprises a spline shaft yoke, a spline shaft, a spline sleeve, a universal joint assembly, a bearing plate, a locking plate and a flange yoke, wherein the spline shaft is welded with the spline shaft yoke into a whole; the spline sleeve is mounted on the spline shaft in a sleeving manner and is connected with the spline shaft in a sliding manner; the spline sleeve and the universal joint assembly are manufactured into a whole; an oil-injecting nozzle is arranged on the spline sleeve; an oil seal is mounted at the left end of the spline sleeve and is in threaded connection with the oil sealing cover at the left end of the spline sleeve for pressing; a blocking cap is mounted at the right end of the spline sleeve; small holes communicated with the atmosphere are formed in the blocking cap. According to the utility model, the transmission shaft is simple in structure, telescopic in total length, can adapt to the requirements for length variation, light in weight, small in vibration during high-speed rotating, and high in rigidity.

Description

A kind of New-type transmission shaft

Technical field

The utility model relate to a kind of can be by the transmission of torque of speed changer to the transmission shaft on ransaxle, especially a kind of New-type transmission shaft.

Background technique

Transmission shaft with ransaxle generally all longer compared with semiaxis, and rotating speed is high again, and due to constantly variation of the relative position between two connected parts, therefore require the length of transmission shaft also will correspondingly change, to ensure normal transmission, existing transmission shaft is in order to meet the variation of propeller shaft length, mostly complex structure, when high speed rotating, vibration is large and overall weight is larger.

Model utility content

The utility model is intended to address the above problem, and a kind of New-type transmission shaft is provided, and it is simple in structure, and total length has extending amount, can adapt to the needs of its length change, lightweight, vibrates littlely when high speed rotating, and rigidity is large, and its technological scheme adopting is as follows:

A kind of New-type transmission shaft, it is characterized in that, comprise: slip shaft yoke, splined shaft, spline housing, universal joint assembly, supporting slice, locking plate and flange yoke, described splined shaft and slip shaft yoke are welded in one, described spline housing is set on splined shaft and with splined shaft and is slidably connected, described spline housing and universal joint assembly are made one, on described spline housing, there is pump nozzle, oil sealing is equipped with at the left end place of described spline housing, described oil sealing is compressed by the oil seal cover that is threadedly connected to spline housing left end, blanking cover is equipped with at the right-hand member place of described spline housing, on described blanking cover, offer the aperture communicating with atmosphere.

On technique scheme basis, described splined shaft is hollow shaft.

On technique scheme basis, described splined shaft is rolled and is welded into by the some blocks of uniform steel plates of thickness.

Compared with prior art, the utlity model has following advantage: simple in structure, total length has extending amount, can adapt to the needs of its length change, lightweight, when high speed rotating, to vibrate littlely, rigidity is large.

Brief description of the drawings

Fig. 1: the structural representation that partly cuts open of the present utility model;

Embodiment

Below in conjunction with accompanying drawing and example, the utility model is described in further detail:

Here it should be noted that, following noun of locality left and right is all to define taking the view shown in Fig. 1 as benchmark, should be appreciated that the use of the described noun of locality should not limit the protection domain that the application asks.As shown in Figure 1, a kind of New-type transmission shaft of the present utility model, it is characterized in that, comprise: slip shaft yoke 1, splined shaft 11, spline housing 4, universal joint assembly 5, supporting slice 6, locking plate 7 and flange yoke 9, described splined shaft 11 is welded in one with slip shaft yoke 1, described spline housing 4 is set on splined shaft 10 and with splined shaft 11 and is slidably connected, described spline housing 4 is made one with universal joint assembly 5, on described spline housing 4, there is pump nozzle 10 to lubricate splined section, oil sealing 2 is equipped with at the left end place of described spline housing 4, described oil sealing 2 is compressed by the oil seal cover 3 that is threadedly connected to spline housing 4 left ends, blanking cover is equipped with at the right-hand member place of described spline housing 4, on described blanking cover, offer the aperture communicating with atmosphere, it should be noted that herein because of the viscosity of lubricant oil larger, the size that aperture is offered should be with can be by air but can not be advisable by lubricant oil, the object of offering aperture is for deaeration, oil sealing 2, oil seal cover 3 and blanking cover work to prevent oil leak jointly.Because this transmission shaft is mainly made by two sections, centre is connected with spline housing with splined shaft, and like this, the total length of transmission shaft has allowed flexible, to adapt to the needs of its length change.

Preferably, described splined shaft 11 is hollow shaft, and this is because in the case of the onesize torque of transmission, hollow shaft has larger rigidity compared with solid shaft, and lightweight, saving steel.

Because splined shaft 11 is driving components of high speed rotating, there is high vibration for fear of the quality of splined shaft 11 because of skewness along the circumferential direction, preferred, described splined shaft 11 is rolled and is welded into by the some blocks of uniform steel plates of thickness, and does not adopt seamless steel pipe.

With way of example, the utility model is illustrated above, but the utility model is not limited to above-mentioned specific embodiment, all any changes of doing based on the utility model or modification all belong to the claimed scope of the utility model.
