Abstract
The utility model relates to an electric roller and a mechanical transmission connection device which is a plunger shaft joint for the electric roller. The plunger shaft joint comprises a left coupling and a right coupling both of which are connected through a plunger; a plunger hole arranged on the left coupling and the right coupling is composed of two holes with different diameters, the plunger hole is big in the inner end and small in the outer end. The improved plunger shaft joint is not needed to be drilled through with equal diameter due to the plunger hole, the plunger is prevented from falling off from the plunger hole, thereby a retaining plate, a hexagonal bolt and a spring washer are not needed in the utility model, the assembly working time is saved, the abrasion to the drill bit is reduced, the structure is simplified and the cost is saved.
Description
Technical field
The utility model relates to a kind of motorized pulleys and other mechanical transmission connection set, i.e. motorized pulleys pin coupler.
Background technique
In the prior art, elastic dowel pin shaft coupling is applicable to the transmission shaft of various mechanical coupling two coaxial lines, is generally used for starting frequent high low speed transmission.Elastic dowel pin shaft coupling has simple in structure, and rationally, easy to maintenance, two sides is symmetrical interchangeable, and the life-span is long, allows bigger axial float, has buffering, damping, performance such as wear-resisting.Pin coupler comprises left and right shaft coupling, and by connecting along the pin of left and right coupling circumferential lateral arrangement, column pin hole is a through hole, and left and right shaft coupling both sides need increase baffle plate, hexagon head bolt, spring washer and block pin (as Fig. 1,2).Its shortcoming is a complex structure, the cost height.
The model utility content
The purpose of this utility model is to provide a kind of motorized pulleys pin coupler simple in structure at above-mentioned deficiency.
Technical solution of the present utility model is: motorized pulleys comprise the left and right shaft coupling that connects by pin with pin coupler.Column pin hole is made up of two sector holes that diameter does not wait on the left and right shaft coupling, and inner end, pin aperture is big, and the outer end is little.
The utility model has the advantages that: the pin coupler after the improvement is because column pin hole need not isometrical drilling through, and pin can not pass from column pin hole and come off, and need not to install baffle plate, hexagon head bolt, spring washer, when saving the rigger, reduced the wearing and tearing of drill bit, simple in structure, save cost.
Below in conjunction with accompanying drawing mode of execution of the present utility model is described in further detail.

Fig. 1 is the prior art products structure diagram.
Fig. 2 is Fig. 1 sectional view.
Fig. 3 is the utility model structure diagram.
Fig. 4 is Fig. 3 sectional view.
Embodiment
Referring to Fig. 3,4, pin coupler comprises the left and right shaft coupling 1,2 that connects by pin 3. Column pin hole 4,5 is made up of two sector holes that diameter does not wait on the left and right shaft coupling 1,2.Coupling column pin hole 4,5 on the basis that does not reduce mechanical property need not to drill through after improving, and adds to stay man-hour 3～5mm as pin 3 retaining platforms, and pin 3 shortens 6～10mm, need not baffle plate, hexagon head bolt, spring washer during installation.
Claims (1)
