Abstract
The utility model discloses a kind of sprocket shafts, the sprocket shaft includes sprocket wheel, main shaft and bearing, main shaft includes the first main shaft section and the second main shaft section, and the diameter of the first main shaft section is more than the diameter of the second main shaft section, and the junction of the first main shaft section and the second main shaft section is provided with the shaft shoulder；Bearing is set on the periphery wall of the first main shaft section, sprocket wheel is set on the periphery wall of the second main shaft section and is stuck in the position of the shaft shoulder, the end set of sprocket wheel has gland, the gland is provided centrally with through-hole, the end set of second main shaft section has screw hole, screw hole is corresponding with the position of the through-hole on gland, and bolt passes through the through-hole on gland and is screwed into the screw hole of end of the second main shaft section, is closely pressed in sprocket wheel on the shaft shoulder by gland.The sprocket shaft is reasonable for structure, and the axial force that work middle sprocket applies can be applied on the shaft shoulder, and bearing is not subject to axial force, to make the service life of bearing greatly improve, while can ensure that the concentricity of sprocket wheel and main shaft meets the requirements.
Description
Technical field
The utility model is related to power transmission technology fields, and in particular to a kind of sprocket shaft.
Background technology
Sprocket shaft is for the device to roller passing power.Sprocket shaft in the prior art can transmit during the work time
Axial force makes the service life of bearing reduce.And sprocket wheel is usually welded on main shaft by sprocket shaft in the prior art, due to
The limitation of welding procedure, it is difficult to ensure that the concentricity of sprocket wheel and main shaft meets the requirements.
Invention content
The purpose of this utility model is to provide a kind of sprocket shafts, and the technical problem to be solved is that how to avoid sprocket shaft
Axial force can be transmitted during the work time, improves the service life of bearing, while ensureing that the concentricity of sprocket wheel and main shaft conforms to
It asks.
Sprocket shaft described in the utility model includes sprocket wheel, main shaft and bearing, the main shaft include the first main shaft section and
Second main shaft section, the diameter of the first main shaft section is more than the diameter of the second main shaft section, in the company of the first main shaft section and the second main shaft section
The place of connecing is provided with the shaft shoulder；The bearing is set on the periphery wall of the first main shaft section, and the sprocket wheel is set in the second main shaft
On the periphery wall of section and it is stuck in the position of the shaft shoulder, the end set of the sprocket wheel has gland, which is provided centrally with
The end set of through-hole, the second main shaft section has screw hole, and screw hole is corresponding with the position of the through-hole on gland, and bolt passes through on gland
Through-hole is simultaneously screwed into the screw hole of end of the second main shaft section, is closely pressed in sprocket wheel on the shaft shoulder by gland.
The bearing is rolling bearing.
The bearing is bearing with spherical outside surface of usheing to seat.
The main shaft is solid shafting.
The main shaft is hollow shaft.
The technical solution of the utility model has the following advantages that：
Sprocket shaft described in the utility model is reasonable for structure, and the axial force that work middle sprocket applies can be applied on the shaft shoulder,
Bearing is not subject to axial force, to make the service life of bearing greatly improve, while can ensure the concentricity of sprocket wheel and main shaft
It meets the requirements.
Description of the drawings
Fig. 1 is the structural schematic diagram of sprocket shaft described in the utility model.
Specific implementation mode
The following examples illustrate the utility model, but is not intended to limit the scope of the present invention.
As shown in Figure 1, sprocket shaft described in the utility model includes sprocket wheel 1, main shaft 2 and bearing 3, the main shaft 2 packet
The first main shaft section 21 and the second main shaft section 22 are included, the diameter of the first main shaft section is more than the diameter of the second main shaft section, in the first main shaft
The junction of section and the second main shaft section is provided with the shaft shoulder 6；The bearing 3 is set on the periphery wall of the first main shaft section, described
Sprocket wheel 1 be set on the periphery wall of the second main shaft section and be stuck in the position of the shaft shoulder, the end set of the sprocket wheel 1 has pressure
Lid 4, the gland are provided centrally with through-hole, and the end set of the second main shaft section has screw hole, the position of screw hole and the through-hole on gland
Correspondence is set, bolt 5 passes through the through-hole on gland and is screwed into the screw hole of end of the second main shaft section, closely pressed sprocket wheel by gland
On the shaft shoulder.
The bearing is rolling bearing.
The bearing is bearing with spherical outside surface of usheing to seat.
The main shaft is solid shafting.
The main shaft is hollow shaft.
The shaft shoulder described in the utility model bears the axial force of work middle sprocket application, and bearing is not subject to axial force, from
And the service life of bearing is made to greatly improve, simultaneously because sprocket wheel is closely pressed on the shaft shoulder using bolt and gland, eliminate
The undesirable problem of the concentricity of sprocket wheel and main shaft caused by the limitation of welding procedure.
Bearing with spherical outside surface of usheing to seat has aligning function, is easily installed, can also be lubricated the supplement of fat, in being easy to use
Maintenance, be a kind of to install and use all very easy bearing.
Although above having made detailed description to the utility model with generality explanation and specific embodiment,
On the basis of the utility model, it can be made some modifications or improvements, this is apparent to those skilled in the art
's.Therefore, these modifications or improvements on the basis of without departing from the spirit of the present invention, belong to the utility model and want
Seek the range of protection.
