Abstract
The utility model discloses a can dismantle combination formula cognate gear, including gear underplate, gear ring, the central authorities of gear underplate set up the location boss, the central authorities of location boss set up connecting shaft hole, the gear underplate is that the components of a whole that can function independently is independent with the gear ring, carry out fixed connection through a plurality of connecting holes on the gear intra -annular ring between gear underplate and the gear ring. Lay a layer of polyurethane layer on connecting shaft hole's the inner wall, this setting can be guaranteed at gear operation in -process sound forer a short time, vibrates forer a short time, makes it difficult and takes place displacement or damage. The utility model discloses be divided into the split type structure of gear ring sum gear underplate with the overall structure of cognate gear, when the gear tooth odontogenesis damage circumstances, only more the gear changing ring can, unnecessary whole gear, the use amount of having practiced thrift the gear changed.
Description
Technical field
The utility model relates to the technical field that Gear Processing manufactures, and more particularly, relates to a kind of Demountable combined-type cognate gear.
Background technique
Gear is part common in machining, traditional gear is an all-in-one-piece structure, carries out interlock transmission by the tooth of outer, because gear is unitary construction, as long as a profile of tooth there occurs damage, may be able to just can not continue again to employ by gear.Cognate gear is the one of gear, and the teeth of cognate gear are comparatively large, and what be in operation is stressed comparatively large, but motion speed is unhappy.According to this handling characteristics of cognate gear, the overall structure of cognate gear is divided into the split type structure of gear ring and gear basal disc by our plan, be conducive to like this, when damage occurs profile of tooth, only changing gear ring, will not changing by whole gear.Save the use amount of gear to a great extent.
Summary of the invention
Goal of the invention: for the deficiencies in the prior art, claimant, through repeatedly putting into practice improvement, devises a kind of Demountable combined-type cognate gear, the overall structure of cognate gear is divided into the split type structure of gear ring and gear basal disc, when wheel tooth odontogenesis damage situation, only change gear ring.
Technological scheme: in order to realize foregoing invention object, the technological scheme that the utility model adopts is: a kind of Demountable combined-type cognate gear, comprise gear basal disc, gear ring, the central authorities of described gear basal disc arrange positioning boss, the central authorities of described positioning boss offer connecting shaft hole, described gear basal disc and gear ring be split independently, described gear basal disc is connected with being fixed by the some attachment holes in gear ring inner ring between gear ring.
Further, on described gear basal disc, the position corresponding with attachment hole is provided with tapped hole, gear basal disc and gear ring is connected and fixed by rivet or screw.
The inwall of described connecting shaft hole lays one deck polyurethane layer, this setting can ensure that sound is less in gear running, shakes less, makes it not easily to be subjected to displacement or to damage.
Beneficial effect: compared with prior art, its beneficial effect is the utility model:
1, the overall structure of cognate gear is divided into the split type structure of gear ring and gear basal disc by the utility model, when wheel tooth odontogenesis damage situation, only changes gear ring, need not change whole gear, save the use amount of gear;
2, the utility model lays one deck polyurethane layer on the inwall of connecting shaft hole, and this setting can ensure that sound is less in gear running, shakes less, makes it not easily to be subjected to displacement or to damage.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of Demountable combined-type cognate of the utility model gear.
Embodiment
Below by a most preferred embodiment, the technical program is described in detail, but protection domain of the present utility model is not limited to described embodiment.
As shown in Figure 1, a kind of Demountable combined-type cognate gear, comprise gear basal disc 1, gear ring 2, the central authorities of described gear basal disc 1 arrange positioning boss 4, the central authorities of described positioning boss 4 offer connecting shaft hole 5, described gear basal disc 1 and gear ring 2 be split independently, described gear basal disc 1 is connected with being fixed by the some attachment holes 3 in gear ring 2 inner ring between gear ring 2.
On described gear basal disc 1, the position corresponding with attachment hole 3 is provided with tapped hole.
The inwall of described connecting shaft hole 5 lays one deck polyurethane layer.
The above is only preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
