Abstract
The utility model relates to a load limiting type drum gear coupling. The load limiting type drum gear coupling comprises an outer gear shaft sleeve, an inner gear ring, a connecting plate, a lining sleeve, an expanding sleeve, a sealing plate and an O-shaped ring, wherein the outer gear shaft sleeve is installed on a shaft extension of a transmission component, the inner gear ring is meshed with the outer gear shaft sleeve, the connecting plate and the expanding sleeve are arranged on a shaft of a working component, the lining sleeve is tightly arranged on the connecting plate, the sealing plate is arranged on the outer gear shaft sleeve, and the O-shaped ring is arranged on the inner gear ring. The load limiting type drum gear coupling further comprises a pin sleeve and a safety pin, wherein the pin sleeve and the safety pin connect the inner gear ring and the connecting plate together. Due to the fact the pin sleeve and the safety pin are arranged, when overload occurs, the safety pin is cut off, the inner gear ring is no longer connected with the connecting plate, a working machine stops working, a transmission component of used equipment is free from damage, and use cost and maintenance cost of the equipment are lowered.
Description
Technical field
The utility model relates to a kind of coupling, relates in particular to a kind of distance-limiting type drum-shaped tooth type shaft coupling.
Background technique
Existing JB/T8854.2-2001 drum-shaped tooth type shaft coupling forms by the identical ring gear of the number of teeth with the parts such as half-coupling of external tooth.Its external tooth is crowned teeth, can allow larger angular displacement, improves the contact conditions of tooth, increases the service life.But this coupling does not possess safety protection function.
The model utility content
Technical problem to be solved in the utility model provides a kind of distance-limiting type drum-shaped tooth type shaft coupling, overcomes that coupling does not possess the safety protection function defective in the prior art.
The technological scheme that the utility model solves the problems of the technologies described above is as follows: a kind of distance-limiting type drum-shaped tooth type shaft coupling, described externality shaft, ring gear, land, lining, expansion set, seal disc, the O type circle of comprising, described externality shaft is installed on the shaft extension of transmission part; Described ring gear and the engagement of described externality shaft; Described land and expansion set are installed on the axle of workpiece; Described lining is tightly packed on the land; Seal disc is contained on the externality shaft, and O type circle is contained on the ring gear, also comprises guide, safety pin, and described guide and safety pin link together ring gear and land.
The beneficial effects of the utility model are: increase guide and safety pin at the distance-limiting type drum-shaped tooth type shaft coupling, when overburdening, safety pin is cut off, ring gear no longer is connected with land, the working machine stall makes the transmission part of equipment exempt from damage, reduces use and the maintenance expenses of equipment.
Description of drawings
Fig. 1 is the utility model distance-limiting type drum-shaped tooth type shaft coupling structural representation.
In the accompanying drawing, the part of each label representative is as follows:
1, externality shaft, 2, seal disc, 3, O type circle, 4, ring gear, 5, lining, 6, guide, 7, safety pin, 8, land, 9, expansion set.
Embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used for explaining the utility model, is not be used to limiting scope of the present utility model.
As shown in Figure 1, a kind of distance-limiting type drum-shaped tooth type axial organ comprises externality shaft 1, ring gear 4, land 8, lining 5, expansion set 9, seal disc 2, O type circle 3, and described externality shaft 1 is installed on the shaft extension of transmission part; Described ring gear 4 and described externality shaft 1 engagement; Described land 8 is installed on the axle of workpiece with expansion set 9; Described lining 5 is tightly packed on the land 8; Seal disc 2 is contained on the externality shaft 1, and O type circle 3 is contained on the ring gear 4; Also comprise guide, safety pin, described guide 6 and safety pin 7 link together ring gear 4 and land 8.
During the normal operation of the utility model distance-limiting type drum-shaped tooth type shaft coupling, all coupler component parts are connected as a single entity, and transmission part is rotated with workpiece.When overburdening, safety pin 7 is cut off, and ring gear 4 no longer is connected with land 8, the working machine stall.Under the effect of transmission part, externality shaft 1 dallies around lining 6 with ring gear 4, and the protection transmission part is not damaged.
The above only is preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
