Because motor shaft is per se with keyway, this just determines that the bushing being mounted on motor shaft must be with keyway, he
Between must be key connection.
The utility model has the following beneficial effects: convenient disassembly, avoids damage to the key connection on motor shaft when replacing belt pulley,
Motor shaft is effectively protected, the service life of motor is extended, has saved production cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model,
In figure: 1, belt pulley, 2, bushing, 3, back of the body cap, 4, cascaded surface, 5, bolt hole, 6, motor shaft through-hole, 7, circle
Connected in star.
Specific embodiment
It is practical new to this in the following with reference to the drawings and specific embodiments in order to be more clear the structure and function of utility model
Type is described further.
A kind of improved motor belt wheel assembly, including belt pulley 1, bushing 3 and back of the body cap 4,1 internal diameter of belt pulley are taper
Bushing 2 is arranged at bellmouth for hole, and 2 outer diameter of bushing is matched with the taper of bellmouth, and bushing inner diameter is motor shaft through-hole 6, belt
It takes turns and circular groove 7 is set close to the side of bushing smaller diameter end, circular groove 7 is connected with the bellmouth of 1 internal diameter of belt pulley, institute
It states bushing smaller diameter end and extend out to circular groove 7, bushing smaller diameter end is connect by back of the body cap 3 with belt pulley 1, and the setting of back of the body cap 3 exists
In circular groove 7 and it is fastened on Outer Diameter of lining.
Further, 3 internal diameter of back of the body cap has internal screw thread, and bushing smaller diameter end stretches out the outer diameter band of circular groove part
There is external screw thread, back of the body cap 3 and bushing 2 are connected through a screw thread fixation.
Back of the body cap 3 and bushing 2 are connected through a screw thread fixation, this component is connected to become an entirety.
Further, the bushing smaller diameter end outer diameter is equipped with stepped opening, and back of the body cap setting is in step type opening and skin
At the cooperation of belt wheel circular groove 7.
Bushing smaller diameter end outer diameter step type opening is escape, first is that in order to process the screw thread side of bushing minor diameter outer end
Just, second is that in order to contact back of the body cap 3 and belt pulley 1 closely, and then keep structure more stable.
Further, the cascaded surface 4 and back of the body cap gap setting of the stepped opening.
The cascaded surface 4 and back of the body cap gap setting of step type opening, avoid interference with when being turnery processing bushing external screw thread withdrawing
Outer Diameter of lining and be arranged.
Further, the back of the body cap 3 is evenly distributed with several bolts hole 5 being axially arranged far from the side of belt pulley 1.
Back of the body cap 3 far from the side of belt pulley 1 be evenly distributed with several bolts hole 5 being axially arranged be in order to install back of the body cap and
The mounting hole of design, when installation, back of the body cap is installed manually first, is further locked back of the body cap with tool finally by mounting hole.
1. the bolt hole of back of the body cap is connecting bushing and belt pulley, an end face of back of the body cap abuts belt pulley end face, passes through
Threaded connection in back of the body cap, back of the body cap is locked, and locks belt pulley to bushing big end, to be fastened on bushing, the spiral shell of back of the body cap
Keyhole connection plays the role of positioning to taper hole connection.
The connection of belt pulley and bushing is fastened more 2. back of the body cap connects at end diameter, prevents belt pulley from using
Cheng Zhong, because abrasion causes the cooperation between bushing and belt pulley to generate sliding downwards due to there is gap.
3. the advantages of being connected using back of the body cap is, it is connected through a screw thread so that total is more stable, can effectively extends
The service life of this component.
Further, the bushing inner diameter is provided with keyway, and bushing is installed on motor shaft in a manner of being keyed.
Because motor shaft is per se with keyway, this just determines that the bushing being mounted on motor shaft must be with keyway, he
Between must be key connection.
The lagging material is 45 steel.
As shown in Figure 1, M250A composite pulley structure, is made of flat-belt pulley 1, bushing 2, back of the body cap 3.Specifically installed
Journey is as follows: first spliting composite members, is then installed to bushing 2 on motor shaft in a manner of key connection, then belt pulley 1 is pacified
On bushing 2, finally back of the body cap 3 is fastened on bushing 2.
The composite pulley structure is simple, installation, convenient disassembly, and since lagging material is 45 steel, rigidity is good, and internal group
Stabilization is knitted, is hardly damaged, when replacing belt pulley, only belt pulley need to be removed from bushing, effectively protect motor shaft, prolong
The service life for having grown motor, has saved production cost.In addition, the taper and M250A grinding wheel spindle of bushing and belt pulley internal taper hole
Taper is consistent, increases the stability of structure.
The utility model has the advantage that
1. lagging material is 45 steel, rigidity is good, reduces motor oscillating and gives processing bring size scattered error；
2. making it easier to fasten after bushing opening, rotational stabilization is improved；
