Abstract
The utility model discloses a kind of smooth-going sliding gear that reverses gear of putting into gear, comprise gear, the center of described gear is provided with central through bore, internal spline is provided with in described central through bore, one end of described gear periphery wall is provided with gear of putting into gear, the other end is provided with fork slot, described in put into gear all gear teeth of gear be equipped with towards one end of described fork slot the arc envelope face formed by circular arc chamfering.By arranging arc envelope face in face of gear one end to fork slot of putting into gear, when gear of putting into gear engages with other gear structures, due to the existence in this arc envelope face, touch between the gear teeth of gear and the gear teeth of other gear structures even if put into gear, arc envelope face also can produce a tangent line component, make the gear teeth of other gear structures along this smooth-going movement in arc envelope face, the operation of the engagement and final realization is put into gear, therefore, by arranging arc envelope face, the operation that can make to put into gear is more smooth-going, avoids occurring colliding with and the phenomenon such as bite.
Description
Technical field
The utility model belongs to technical field of mechanical transmission, is specifically related to a kind of smooth-going sliding gear that reverses gear of putting into gear.
Background technique
Gearbox is made up of gear and axle, and produce variable-speed torque-converting by different Gear combination, its function mainly contains: 1, change velocity ratio; 2, in the constant situation of hand engine rotation, automobile can be fallen back traveling; 3, utilize neutral, interrupt transmission of power, to start to enable motor, idling, and be convenient to shift of transmission or carry out Power output.Although existing gear box reverse gear sliding gear can meet usage requirement to a certain extent, when putting into gear, often there is the phenomenon of colliding with bite, making operation irregularity of putting into gear.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of smooth-going sliding gear that reverses gear of putting into gear, and slides more smooth-going when putting into gear.
For achieving the above object, the utility model provides following technological scheme:
A kind of smooth-going sliding gear that reverses gear of putting into gear, comprise gear, the center of described gear is provided with central through bore, internal spline is provided with in described central through bore, one end of described gear periphery wall is provided with gear of putting into gear, the other end is provided with fork slot, described in put into gear all gear teeth of gear be equipped with towards one end of described fork slot the arc envelope face formed by circular arc chamfering.
Further, the middle part of described central through bore is provided with the separation annular groove for described internal spline being divided into two ends.
Further, the external diameter in described arc envelope face reduces gradually along the radially outer direction of described gear.
Further, seamlessly transit between described arc envelope face with the two side of the corresponding described gear teeth.
Further, the symmetrical line in described arc envelope face is the oblique line of inclination relative to the axis of described gear.
Further, the angle between the symmetrical line in described arc envelope face and the axis of described gear is 75-80 °.
Further, in described arc envelope face, the center of circle of all circular arcs is all positioned at on the straight line of the axes normal of described gear.
The beneficial effects of the utility model are:
The smooth-going sliding gear that reverses gear of putting into gear of the present utility model, by arranging arc envelope face in face of gear one end to fork slot of putting into gear, when gear of putting into gear engages with other gear structures, due to the existence in this arc envelope face, touch between the gear teeth of gear and the gear teeth of other gear structures even if put into gear, arc envelope face also can produce a tangent line component, make the gear teeth of other gear structures along this smooth-going movement in arc envelope face, the operation of the engagement and final realization is put into gear, therefore, by arranging arc envelope face, can making to put into gear, it is more smooth-going to operate, avoid occurring colliding with and the phenomenon such as bite.
Accompanying drawing explanation
In order to make the purpose of this utility model, technological scheme and beneficial effect clearly, the utility model provides following accompanying drawing to be described:
Fig. 1 is that the utility model is put into gear the structural representation of smooth-going sliding gear embodiment of reversing gear;
Fig. 2 is the A detail drawing of Fig. 1;
Fig. 3 is the B-B sectional drawing of Fig. 2.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, and to make those skilled in the art better can understand the utility model being implemented, but illustrated embodiment is not as to restriction of the present utility model.
As shown in Figure 1, for the utility model is put into gear the structural representation of smooth-going sliding gear embodiment of reversing gear.The smooth-going sliding gear that reverses gear of putting into gear of the present embodiment, comprise gear 1, the center of described gear 1 is provided with central through bore 2, internal spline 3 is provided with in described central through bore 2, one end of described gear 1 periphery wall is provided with gear 4 of putting into gear, the other end is provided with fork slot 5, described in put into gear all gear teeth of gear 4 be equipped with towards one end of described fork slot 5 the arc envelope face 6 formed by circular arc chamfering.The middle part of the central through bore 2 of the present embodiment is provided with the separation annular groove 7 for described internal spline 3 being divided into two ends.
