Description
Technical field
The utility model relates to a kind of combined worm gear, belongs to worm gear technical field.
Background technique
At present, worm gear is a driving parts, the material of general worm gear adopts brass, the mode connected with worm gear generally all adopts the mode of keyway, when the part connected with worm gear is stressed larger in rotation process, and positive and negative direction rotates, worm gear keyway is easy to produce enlargement phenomenon, and the connection between part was lost efficacy.
Summary of the invention
Technical problem to be solved in the utility model is the defect overcoming prior art, provides a kind of combined worm gear, wear-resisting property when it not only ensure that worm gear engages, and improves the linking intensity of worm gear.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of combined worm gear, and it comprises:
Worm gear core, described worm gear core is made up of carbon steel or spheroidal graphite cast iron or gray cast iron material;
Worm gear meshing teeth, described worm gear meshing teeth is bonded in the outer rim of worm gear core, and worm gear meshing teeth is made up of copper material.
Further in order to make the worm gear meshing teeth of worm gear core and casting combine securely, be provided with between described worm gear core and the junction of worm gear meshing teeth to engage and strengthen structure, so that worm gear meshing teeth is bonded together with worm gear core by engaging with strengthening sound construction.
Further provide a kind of concrete structure engaging enhancing structure, described joint strengthens the engagement protrusion that structure comprises the counterbore in the outer rim being arranged on described worm gear core and is arranged on the inner side surface of described worm gear meshing teeth, and counterbore and engagement protrusion match.
Further provide a kind of concrete structure engaging enhancing structure, described joint strengthens the internal thread that structure comprises the outside thread in the outer rim being arranged on described worm gear core and is arranged on the inner side surface of described worm gear meshing teeth, and outside thread and internal thread match.
Further provide a kind of concrete structure engaging enhancing structure, the described bump bonding engaging enhancing structure and comprise the engaging groove in the outer rim being arranged on described worm gear core and be arranged on the inner side surface of described worm gear meshing teeth, engaging groove and bump bonding match.
After have employed technique scheme, worm gear core of the present utility model adopts carbon steel or spheroidal graphite cast iron or gray cast iron material to make, which improves the linking intensity of worm gear core, worm gear meshing teeth keeps original copper material to make in addition, this ensures that theres wear-resisting property during worm gear engagement; In addition, in order to make the worm gear meshing teeth of worm gear core and casting combine securely, being provided with between described worm gear core and the junction of worm gear meshing teeth and engaging enhancing structure.
Accompanying drawing explanation
Fig. 1 is the structural representation of combined worm gear of the present utility model;
Fig. 2 is the structural representation that worm gear core of the present utility model opens counterbore.
Embodiment
In order to make content of the present utility model more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail.
As shown in Figure 1, 2, a kind of combined worm gear, it comprises:
Worm gear core 1, worm gear core 1 is made up of carbon steel or spheroidal graphite cast iron or gray cast iron material;
Worm gear meshing teeth 2, worm gear meshing teeth 2 is bonded in the outer rim of worm gear core 1, and worm gear meshing teeth 2 is made up of copper material.
Be provided with between the junction of worm gear core 1 and worm gear meshing teeth 2 to engage and strengthen structure, so that worm gear meshing teeth 2 is bonded together with worm gear core 1 by engaging enhancing sound construction ground.
Engage and strengthen structure by following several form, but be not limited to that these are several:
The first is: engage the engagement protrusion strengthening structure and comprise the counterbore 11 in the outer rim being arranged on worm gear core 1 and be arranged on the inner side surface of described worm gear meshing teeth 2, counterbore 11 and engagement protrusion match.
The second is: engage the internal thread strengthening structure and comprise the outside thread in the outer rim being arranged on worm gear core 1 and be arranged on the inner side surface of described worm gear meshing teeth 2, outside thread and internal thread match.
The third is: engage the bump bonding strengthening structure and comprise the engaging groove in the outer rim being arranged on worm gear core 1 and be arranged on the inner side surface of described worm gear meshing teeth 2, engaging groove and bump bonding match.
Working principle of the present utility model is as follows:
Worm gear core 1 of the present utility model adopts carbon steel or spheroidal graphite cast iron or gray cast iron material to make, and which improves the linking intensity of worm gear core, and worm gear meshing teeth 2 keeps original copper material to make in addition, this ensures that theres wear-resisting property during worm gear engagement; In addition, in order to make worm gear core 1 can combine securely with the worm gear meshing teeth 2 of casting, being provided with between described worm gear core 1 and the junction of worm gear meshing teeth 2 and engaging enhancing structure.
Above-described specific embodiment; technical problem, technological scheme and beneficial effect that the utility model solves are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
