Abstract
The invention discloses a ventilation structure of a speed reducer. A shielding part is arranged on the lower portion of an air hole in the high-speed shaft side of the speed reducer and fixed to an installing frame arranged on a speed reducer shell; a collecting, backflow and cooling device is arranged outside the air hole and comprises a shell; an upward protruding part is arranged on the lower portion of the shell and connected to a ventilation pipe stretching out of the air hole in an abutting manner; the ventilation pipe is in a T type, and the lower portion of the ventilation pipe communicates with the speed reducer shell; an outlet is formed in the lower portion of the shell and connected with a pipeline, and the pipeline communicates with a collecting box; and a plurality of through holes are formed in the upper portion of the shell. The ventilation structure of the speed reducer has the beneficial effects that the amount of lubricating oil overflowing from the air hole is decreased, the cooling function of the speed reducer is enhanced, the labor intensity of workers is relieved, the lubricating oil consumption is reduced, and stable running of the speed reducer is guaranteed.
Description
Technical field
The present invention relates to mechanical field, specifically a kind of reductor ventilating structure.
Background technology
Existing DCY, ZQ type reductor ventilating structure is as shown in Figure 1, owing to high-speed gear rotates, reductor operating temperature raises, make air expansion in case, thus pressure raises in case, lubricating oil splash, to reductor upper cover air-vent position, causes that lubricating oil overflows from air-vent, causes reductor upper cover to be frequently present of greasy dirt.
Summary of the invention
For solving above-mentioned technical problem, it is an object of the invention to provide the ventilating structure that a kind of lubricating oil will not overflow, concrete technical scheme is as follows:
A kind of reductor ventilating structure, arranges occlusion part in the air-vent bottom of reductor high speed shaft side, and described occlusion part is fixed on reducer shell on the installing rack of setting；Arranging collection backflow heat abstractor outside air-vent, that collects backflow heat abstractor includes a housing, and lower housing portion arranges lobe upwards, and described lobe is connected on the permeability cell stretched out in air-vent；Described permeability cell is T-shaped, and bottom connects with reducer shell；The bottom of housing arranges outlet, and described outlet is connected with pipeline, and pipeline connects with collecting box；Housing be provided above multiple through hole.
Also including fixing nut, described fixing nut is on air-vent cylinder, and permeability cell embeds in air-vent cylinder, fixing nut compress permeability cell.
The invention have the advantage that minimizing lubricating oil is from air-vent spill-out, strengthens reductor heat sinking function, reduces labor strength, reduces oil consumption, it is ensured that reductor stable operation.
Accompanying drawing explanation
Fig. 1 is existing reductor ventilating structure；
Fig. 2 is the structural representation of the present invention；
Fig. 3 is for collecting backflow construction for heat radiating device schematic diagram.
Detailed description of the invention
Illustrating the present invention below in conjunction with accompanying drawing, as shown in Figure 2 and Figure 3, arrange occlusion part 4 in air-vent 3 bottom of reductor 1 high speed shaft side, air-vent 3 is fixed in mounting seat 2, and described occlusion part 4 is fixed on reducer shell on the installing rack of setting；Arranging collection backflow heat abstractor 5 outside air-vent, collect backflow heat abstractor 5 and include a housing 51, housing 51 bottom arranges lobe 52 upwards, and described lobe 52 is connected on the permeability cell 32 stretched out in air-vent；Described permeability cell 32 is T-shaped, and bottom connects with reducer shell；The bottom of housing 51 arranges outlet 54, and described outlet is connected with 54 pipelines 55, and pipeline 55 connects with collecting box；Housing be provided above multiple through hole 53.
Also including fixing nut 31, described fixing nut 31 is tightened on air-vent cylinder 33, and permeability cell 32 embeds in air-vent cylinder 33, fixing nut 3.1 compress permeability cell 32.
The present invention is by changing the version within reductor air-vent, in reductor high speed shaft side, the air-vent bottom occlusion part according to factor welding different sizes such as the centre-to-centre spacing of reductor, high speed shaft and reductor upper cover distance, air-vent form and positions, intercepts the lubricating oil that gear rotation spray splashes；Ensureing reductor internal pressure balance, gas keeps unimpeded by air-vent with extraneous simultaneously.
The present invention has certain dissemination, is not only used in belt system reductor, the place of conventional DCY, ZQ type reductors such as Overhead travelling crane system, all can adopt this technology.
Claims (2)
