Description
Technical field
The utility model relates to one and utilizes the transmission case of bevel gear (being also the umbrella gear) transmission that commutates, and especially relates to a kind of bevel gear housing with overload protection function.
Background technique
The transmission case (referring to accompanying drawing 2) that utilizes at present bevel gear (being also the umbrella gear) transmission that commutates is to run into output terminal load excessive or while being subject to the situation of obstacle jam, easily cause input shaft impaired with the bevel gear being meshed on output shaft, thereby bring loss and inconvenience.
Model utility content
The technical problems to be solved in the utility model is: in the time running into output terminal overload or be subject to jam situation, easily cause in order to solve existing bevel gear housing the impaired problem of bevel gear being meshed on input, output shaft; and provide a kind of bevel gear housing with overload protection function; this transmission case resistance in the time that output terminal transships or is subject to jam can be cut off voluntarily, impaired thereby the bevel gear in transmission case avoids.
The utility model solves the technological scheme that its technical problem adopts: a kind of bevel gear housing with overload protection function, include casing, input shaft, output shaft, the bevel gear being engaged with each other is installed on input shaft and output shaft separately, the output terminal of output shaft is coaxially installed with output sprocket, on output shaft, be coaxially fixedly installed overload clutch wheel, output sprocket is slidably disposed on output shaft, one end of output sprocket coordinates by the inclined-plane key clamping corresponding to each other with overload clutch wheel, the other end of output sprocket is provided with the spring that holds out against being set on spring locating column, one end of spring locating column is coaxially fixedly connected with the output end of output shaft, the other end of spring locating column is bolted with set screw nut, hold out against one end of spring and the end face of output sprocket pushes against, the end face of the other end and set screw nut pushes against.This overload protection principle of bevel gear housing with overload protection function is as follows: (under the maximum load of permission) in normal operation, output sprocket relies on the pressure that holds out against spring to coordinate by the inclined-plane key clamping corresponding to each other with overload clutch wheel, thereby overload clutch is taken turns transmission of power to output sprocket, exceed limit value or by jam once output sprocket load, overload clutch wheel holds out against the pressure of spring to output sprocket and " jack-up " output sprocket of taking advantage of a situation along the inclined-plane of inclined-plane key by overcoming in the process of rotating, now overload clutch wheel coordinates inefficacy with the clamping of output sprocket, overload clutch wheel still can be with output shaft rotation, like this, the suffered overload resistance of output sprocket just can transfer function on input shaft and output shaft on intermeshing bevel gear, thereby reach excessive in output sprocket load or be subject to bevel gear in the situation lower transmission case of jam to avoid the object of damage.The load threshold limit value of output sprocket can be set up by the spring that holds out against of selecting different elasticity specifications.
Preferably, described to hold out against spring tapered, and its great circle end pushes against the end face of output sprocket, and ringlet end pushes against the end face of set screw nut, thereby guarantees to hold out against uniformity and the stability of spring to pressure that output sprocket is executed.
Say further again; be outside equipped with containment vessel at the described spring that holds out against; containment vessel is fastened and is formed by half shell of two splits; the end face of one of them half shell is pushed against by the one end that holds out against spring on the end face of output sprocket, and the end face of another half shell is pushed against on the end face of set screw nut by the other end that holds out against spring.The object of this scheme is mainly to hold out against spring in order to protect, and makes to hold out against the interference that spring is avoided external force, foreign object.
The beneficial effects of the utility model are: this bevel gear housing with overload protection function in output terminal load excessive or while being subject to jam output terminal resistance can be cut off voluntarily; thereby on input shaft and output shaft, intermeshing bevel gear avoids impairedly in transmission case, avoids unnecessary loss with inconvenient.The structural design exquisiteness of this bevel gear housing with overload protection function on its overload protection function, reasonable, brief, it is convenient to manufacture.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model (broken section).
Fig. 2 is the structural representation (broken section) of existing bevel gear housing.
In figure: 1. casing 2. input shaft 3. output shaft 4. bevel gear 5. output sprocket 6. overload clutch are taken turns 7. spring locating columns 8. and held out against spring 9. set screw nut 10. containment vessels.
Embodiment
A kind of bevel gear housing with overload protection function, as shown in Figure 1, it includes casing 1, input shaft 2, output shaft 3, on input shaft 2 and output shaft 3, the bevel gear 4 being engaged with each other is installed separately, the output terminal of output shaft 3 is coaxially installed with output sprocket 5, on output shaft 3, be coaxially fixedly installed overload clutch wheel 6, output sprocket 5 is slidably disposed on output shaft 3, one end of output sprocket 5 coordinates by the inclined-plane key clamping corresponding to each other with overload clutch wheel 6, the other end of output sprocket 5 is provided with to be set on and holds out against spring 8 on spring locating column 7, one end of spring locating column 7 is coaxially fixedly connected with the output end of output shaft 3, the other end of spring locating column 7 is bolted with set screw nut 9, hold out against one end of spring 8 and the end face of output sprocket 5 pushes against, the end face of the other end and set screw nut 9 pushes against.Hold out against spring 8 tapered, its great circle end pushes against the end face of output sprocket 5, and ringlet end pushes against the end face of set screw nut 9.Be outside equipped with containment vessel 10 holding out against spring 8; containment vessel 10 is fastened and is formed by half shell of two splits; the end face of one of them half shell is pushed against by the one end that holds out against spring 8 on the end face of output sprocket 5, and the end face of another half shell is pushed against on the end face of set screw nut 9 by the other end that holds out against spring 8.
This overload protection principle of bevel gear housing with overload protection function is as follows: (under the maximum load of permission) in normal operation, output sprocket 5 relies on the pressure that holds out against spring 8 to coordinate by the inclined-plane key clamping corresponding to each other with overload clutch wheel 6, thereby overload clutch wheel 6 by transmission of power to output sprocket 5, exceed limit value or by jam once output sprocket 5 loads, overload clutch wheel 6 holds out against the pressure of spring 8 to output sprocket 5 and " jack-up " output sprocket 5 of taking advantage of a situation along the inclined-plane of inclined-plane key by overcoming in the process of rotating, now overload clutch wheel 6 coordinates inefficacy with the clamping of output sprocket 5, overload clutch wheel 6 still can rotate with output shaft 3, like this, the suffered overload resistance of output sprocket 5 just can transfer function on input shaft 2 and output shaft 3 on intermeshing bevel gear 4, thereby reach excessive in output sprocket 5 loads or be subject to bevel gear in the situation lower transmission case of jam to avoid the object of damage.The load threshold limit value of output sprocket 5 can be set up by the spring 8 that holds out against of selecting different elasticity specifications.
Above-described embodiment is only for the utility model of explaining, but not restriction to the utility model rights protection, the change of every any unsubstantiality carrying out on the basis of the utility model essence scheme, all should fall in protection domain of the present utility model.
