Abstract
The utility model discloses a power reversing device and solves the problem that the conventional power reversing device cannot be well suitable for long-distance power transmission. The utility model adopts the technical scheme that: the power reversing device comprises a box body, a driving shaft and a driven shaft, wherein the driving shaft and the driven shaft are vertically arranged in the box body; and a driving gear and a driven gear, which are meshed with each other, are respectively sleeved on the driving shaft and the driven shaft. The power reversing device is characterized in that: the driven shaft is positioned inside the box body; the driving shaft extends out of the box body; and a supporting seat is arranged at an extension end of the driving shaft.
Description
Technical field
The utility model relates to a kind of power reversing arrangement, relates in particular to a kind of power reversing arrangement with vertically disposed driving shaft and driven shaft.
Background technique
In more existing dynamic power machines, sometimes some reversing arrangements need be set, with the direction of transfer of change power, thus the work requirements of adaptation dynamic power machine.
China's utility model patent (patent No.: disclose a kind of power commutator 200920305265.7).It has solved, and existing power commutator structure is complicated, the problem of assembling inconvenience.Structure is: a kind of power commutator, and comprise casing, be located at orthogonal major axis and minor axis on the casing, be equipped with block bearing on major axis and the minor axis; Be respectively equipped with intermeshing angular wheel on major axis and the minor axis; It is characterized in that said casing is provided with side box body, said minor axis is located in the side box body; Side box body is stretched out in the outer end of minor axis, and the block bearing on the minor axis is between side box body and minor axis.
In the power commutator of this structure, because major axis and minor axis all are connected in the casing rotationally, the length of major axis and minor axis generally can be restricted, otherwise will cause the huge of casing volume.And, because long and short axle is arranged in the casing, in the commutator working procedure, between the long and short axle transmission of power will take place, this just requires the intensity of casing itself high.In addition, because the length of long and short axle has certain narrow limitation, this commutator can not adapt to the transmission of power requirement of long distance.
Summary of the invention
For overcoming above-mentioned defective, the utility model technical issues that need to address are: a kind of power reversing arrangement is provided, and it can adapt to long requirement apart from transmission of power, and wherein the rotational stability of major axis is good.
The utility model solve the technical problem the technological scheme of being taked: a kind of power reversing arrangement; Comprise casing, be vertically set on driving shaft and driven shaft in the casing; On driving shaft and driven shaft, be socketed with intermeshing driving gear and driven gear respectively, it is characterized in that, said driven shaft is positioned at box house; Driving shaft reaches the casing outside, at the distolateral supporting base that is provided with of stretching out of driving shaft.Driving gear circumferentially is fixed on the driving shaft, and driven gear circumferentially is fixed on the driven shaft.Driving shaft can have long part to reach the outside of casing, and supporting base is used to support driving shaft, to guarantee driving shaft rotational stability in the course of the work.
As preferably, be socketed with axle sleeve in the periphery of driving shaft, an end and the casing of axle sleeve link; The outer end of driving shaft reaches the outside of axle sleeve the other end; The place, two ends of axle sleeve is provided with block bearing respectively, and block bearing is socketed on the driving shaft, and supporting base is connected on the axle sleeve.Be provided with axle sleeve, improved the Security in the driving shaft rotation process, and be convenient to supporting base and driving shaft links.
As preferably, said block bearing is a tapered roller bearing.Tapered roller bearing can improve the stability in the driving shaft working procedure.
As preferably, said supporting base comprises pedestal and headkerchief, and headkerchief and pedestal are encircled the periphery at driving shaft.This makes is convenient to realize connect between supporting base and driving shaft or the axle sleeve.
As preferably, the biasing of the main body of said pedestal, this main body and driven gear branch are listed in the relative both sides of driving shaft.This has adapted to the working method between driving shaft and the driven shaft well, is convenient to driving shaft rotational stability in the course of the work.
As preferably, the fitting surface between said headkerchief and the pedestal is obliquely installed.This fitting surface is meant to have an angle between this fitting surface and the vertical direction, thereby can conveniently be connected in headkerchief on the pedestal for being obliquely installed.
As preferably, be formed with cavity on the said casing with opening, an end of driven shaft is towards the opening of this cavity, and is positioned at this cavity.Extraneous connecting structure can in this cavity, realize with the driven shaft end between connect, thereby can improve structural compactness, the job security height of power transmitting deice.
The beneficial effect of the utility model is: because the end of driving shaft reaches the outside of casing; And the external part place at driving shaft is provided with supporting base; To guarantee the stability in the driving shaft rotation process; This makes driving shaft can have long part to reach the outside of casing, can adapt to the requirement of this power reversing arrangement length apart from transferring power well.
