Abstract
(B, ) the utility model discloses a gear shaft subassembly be circular shape axis body (3) including the cross -section, and axis body (3) one end is equipped with installation department (5), and the diameter of section of installation department (5) is less than the diameter in the middle part of axis body (3), installation department (5) are gone up the cover and are equipped with gear (1), gear (1) cylindric lock (2) through radial installation with installation department (5) are fixed, axis body (3) other end is equipped with three plane breach (4). The utility model discloses an assembled structure of components of a whole that can function independently has reduced manufacturing cost, assembles moreover and uses the operation also more convenient. (B, )
Description
Technical field
the utility model relates to a kind of gear shaft assembly, particularly a kind of gear shaft assembly for hoist machine jiggering.
Background technique
along with the development of modernization, the use of elevator in people's daily life is more and more frequent.And as the core drive parts of elevator, the demand of hoist machine is also increasing.In the production process of hoist machine, need before dispatching from the factory to carry out jiggering detection to hoist machine, and jiggering testing process uses gear shaft to carry out usually.But current most gear shaft is all machined into integral structure out, and this structure certainly will make the cost of production of gear shaft too high.
Model utility content
the purpose of this utility model is, provides a kind of gear shaft assembly.It adopts assembled structure, reduces cost of production, and assembles and use operation also more convenient.
the technical solution of the utility model: gear shaft assembly, be characterized in: comprising cross section is circular axis body, axis body one end is provided with assembly department, the diameter of section of assembly department is less than the diameter in the middle part of axis body, described assembly department is arranged with gear, and described gear is fixed by the radial straight pin installed and described assembly department; The described axis body the other end is provided with three plane breach.
in above-mentioned gear shaft assembly, described three plane breach equal and opposite in directions, and distance is between any two equal, and the cross section of plane breach be axis body cross section on string, and the central angle of correspondence is 60 ° ~ 80 °.It is similar leg-of-mutton structure that such breach setting can form a cross section, for connecting handwheel to provide enough moments of torsion.And the size of plane breach is arranged, not only can provide larger moment, and structural strength is also larger.
compared with prior art, the utility model is coordinated by the axis body of special shape has installed gear, defines a processing more simple, assembling gear shaft assembly very easily, can be effective to the jiggering test of hoist machine.
Accompanying drawing explanation
fig. 1 is structural representation of the present utility model;
fig. 2 is the right elevation of Fig. 1.
being labeled as in accompanying drawing: 1-gear, 2-straight pin, 3-axis body, 4-plane breach, 5-assembly department.
Embodiment
below in conjunction with drawings and Examples, the utility model is further described, but not as the foundation limited the utility model.
embodiment.Gear shaft assembly, as depicted in figs. 1 and 2: comprising cross section is circular axis body 3, axis body 3 one end is provided with assembly department 5, the diameter of section of assembly department 5 is less than the diameter in the middle part of axis body 3, described assembly department 5 is arranged with gear 1, and described gear 1 is fixed by the radial straight pin 2 installed and described assembly department 5; Described axis body 3 the other end is provided with three plane breach 4.Described three plane breach 4 equal and opposite in directions, and distance is between any two equal, and the cross section of plane breach 4 be axis body 3 cross section on string, and the central angle of correspondence is 60 ° ~ 80 °.
during installation, only gear 1 need be inserted in the assembly department 5 of axis body 3 one end, then be fixed with straight pin 2 pairs of gears 1.During use, gear 1 is loaded hoist machine, and axis body 3 the other end is connected with handwheel.
