Abstract
The utility model discloses a separate herringbone gear shaft, which comprises a herringbone gear shaft sleeve and a splined shaft, and is characterized in that an inner spline or an outer spline is arranged in an inner hole of the herringbone gear shaft sleeve, the splined shaft is provided with the outer spline and the inner spline, and the herringbone gear shaft sleeve is fixedly connected with the splined shaft through the inner and the outer splines. Because a herringbone gear shaft is designed into a separated structure, the herringbone gear shaft sleeve and the splined shaft are connected together in a spline connected mode to form the herringbone gear shaft. When working, circumferential load between the herringbone gear shaft sleeve and the splined shaft is transmitted through the splines, left and right gear teeth are centered by axial play of the herringbone gear shaft sleeve on the splined shaft, and the axial play of the herringbone gear shaft is avoided. The separate herringbone gear shaft can meet centering demands of herringbone gears, and also avoids the axial play of the splined shaft, thereby further eliminating axial impact to bearings and external connection equipment, and prolonging service life and increasing reliability of equipment.
Description
Technical field
The utility model belongs to mechanically operated herringbone gear shaft technical field, and what relate generally to is a kind of separated type herringbone gear shaft.
Background technique
Herringbone gear is a kind of cylindrical gears, is right-hand teeth in certain a part of facewidth, and is left-hand teeth in another part facewidth.It has advantages such as bearing capacity height, stable drive and thrust load are little, is widely used in the transmission system of heavy machinery.Because during known herringbone gear auxiliary driving, for realizing gear pair left and right sides gear teeth automatic centering, require an axial restraint in driving wheel parts and the follower parts, another axial float, consequent problem is: the geared parts that floats can produce axial float when working, external equipment and the spring bearing that is attached thereto produced bigger impact, influence working life and the reliability of spring bearing and associated devices.
The model utility content
The utility model purpose proposes a kind of separated type herringbone gear shaft at existing deficiency in the above-mentioned prior art just.By adopting the separated type herringbone gear shaft, solved the problem of herringbone gear parts generation additional axial force, avoided the influence to bearing and outside connecting device, effectively improved working life and the reliability of equipment.
The purpose of this utility model can realize by following technique measures:
Separated type herringbone gear shaft of the present utility model comprises herringbone gear axle sleeve and splined shaft, endoporus at the herringbone gear axle sleeve is provided with internal spline or external splines, be provided with external splines or internal spline at splined shaft, herringbone gear axle sleeve and splined shaft are fixedly connected by inside and outside spline.
The spline teeth of internal spline described in the utility model or external splines is rectangle or trapezoidal.
The beneficial effects of the utility model are as follows:
The utility model is owing to be designed to separation structure with herringbone gear shaft, and by the mode of splined herringbone gear axle sleeve and splined shaft is linked together, and forms a herringbone gear shaft.During work, transmit circumferential load between herringbone gear axle sleeve and the splined shaft by spline, and be enclosed within the centering that the axial float on the splined shaft is realized the left and right sides gear teeth by herringbone gear shaft, avoided the axial float of whole herringbone gear shaft.Can satisfy herringbone tooth centering needs have also been avoided the axial float of splined shaft, and then eliminate bearing and outside connecting device axial impact.Working life and the reliability of equipment have been improved.
Description of drawings
Fig. 1 is the utility model package assembly schematic representation.
Fig. 2 is the utility model decomposition texture schematic representation.
Among the figure: 1, herringbone gear axle sleeve, 2, splined shaft.
Embodiment
By reference to the accompanying drawings, it is as follows to provide embodiment of the present utility model:
As Fig. 1 in conjunction with shown in Figure 2: the described separated type herringbone gear shaft of present embodiment comprises herringbone gear axle sleeve 1 and splined shaft 2, described herringbone gear axle sleeve 1 and splined shaft 2 are known conventional structure, endoporus at herringbone gear axle sleeve 1 is provided with internal spline or external splines, be provided with external splines or internal spline at splined shaft 2, spline teeth can be rectangle, trapezoidal etc., herringbone gear axle sleeve 1 passes through splined together with splined shaft 2, forms a herringbone gear shaft.During work, transmit load between herringbone gear axle sleeve and the splined shaft by spline, and be enclosed within the centering that the axial float on the splined shaft is realized the left and right sides gear teeth by herringbone gear shaft.
