Abstract
The utility model relates to a roller chain coupler which is used for transmitting torques among large-diameter rotation shafts in large mechanical equipment. The roller chain coupler comprises a pair of shaft sleeves which are provided with chain wheel gears; two groups of chain wheel gears on the two shaft sleeves are connected with each other by two lines of roller chains which are integrated into a whole and transmit the torques; the axial thickness of the root of the chain wheel gear is more than that of the position of the upper part thereof matched with the roller chain; namely, the transition part of the root of the chain wheel tooth and the external wall of the shaft sleeve is provided with a ring-shaped step. The roller chain coupler has the advantages of compact structure, high strength and reliable usage.
Description
Technical field
The utility model relates to and is used for the double roller chain coupling of between large-diameter shaft transmitting torque in the heavy mechanical equipment.
Background technique
The structure of common double roller chain coupling and specification have relevant regulations in NBS, the two row roller chains that its structure generally comprises a pair of axle sleeve and connects as one, the end relative at two axle sleeves is provided with sprocket tooth, two row roller chains cooperate with two groups of sprocket tooth that diaxon puts, and realize the connection between two axle sleeves.When the double roller chain coupling of this structure surpasses the recommendation specification of existing NBS when the moment of torsion of the rotating shaft size of its application and transmission, the intensity of its sprocket tooth part often can't adapt to the usage requirement of high pulling torque, deforms easily in running and reduces operational safety; In addition, because the sprocket tooth in the conventional construction on two axle sleeves is positioned at the relative end of two axle sleeves, with after roller chain is connected, two axle sleeves have bigger distance between the relative end, correspondingly make the axial dimension of whole coupling bigger, cause at it to be difficult to be installed in some axle base small device environment.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of compact structure, intensity height, double roller chain coupling that operational safety is good are provided.
Double roller chain coupling of the present utility model includes a pair of axle sleeve that has sprocket tooth, the roller chain that is connected as a single entity by two row between two groups of sprocket tooth that diaxon puts connects and transmitting torque, the axial thickness of the root of described sprocket tooth is greater than the axial thickness of its top and roller chain mating part, that is, be provided with the step of annular at the transition portion of sprocket tooth root and axle sleeve outer wall.In addition, in two axle sleeve opposing end faces the interior step that stretches to the inboard is set also.
The utility model has improved the intensity of total, thereby can adapt to big specification, the driven off by shaft usage requirement of high pulling torque owing to increased the thickness of sprocket tooth root, has improved operational reliability; Simultaneously, owing to be provided with interior step in the relative end of two axle sleeves, except can further improving sprocket tooth intensity, the corresponding sleeve length that reduces the sprocket tooth outside on each sleeve length basis of invariable can kept simultaneously, thereby the whole axial length after the coupling that can the contract assembling can adapt to the installation requirement of less wheelbase.
Description of drawings
Fig. 1 is a vertical section structure schematic representation of the present utility model.
Embodiment
As shown in the figure, this double roller chain coupling comprises a pair of axle sleeve 1 that has sprocket tooth 11, and the roller chain 2 that is connected as a single entity by two row between two groups of sprocket tooth that diaxon puts connects and transmitting torque.Transition portion at sprocket tooth root and axle sleeve outer wall is provided with annular step 12, and step 13 in the opposing end surface of two axle sleeves is provided with.
Claims (2)
1. double roller chain coupling, include a pair of axle sleeve (1) that has sprocket tooth (11), the roller chain (2) that is connected as a single entity by two row between two groups of sprocket tooth that diaxon puts connects and transmitting torque, it is characterized in that: the axial thickness of the root of described sprocket tooth (11) is greater than the axial thickness of its top and roller chain mating part, that is, be provided with the step (12) of annular at the transition portion of sprocket tooth root and axle sleeve outer wall.
2. double roller chain coupling according to claim 1 is characterized in that: be provided with in two axle sleeve opposing end faces and stretch to inboard interior step (13).
