Abstract
The utility model relates a sealing structure of a motor shaft, which belongs to the technical field of the machinery of motors. The sealing structure of a motor shaft comprises an output shaft and an end cap, wherein the output shaft is extended out from the central hole of the end cap, and an oil seal is arranged in the end cap. The utility model is characterized in that a bearing seat, an oil seal seat and cushion rings for baffling a bearing seat and an oil seal seat are arranged in the end cap, and oil seals and bearings are respectively arranged in the bearing seat and the oil seal seat. The sealing structure of a motor shaft of the utility model has the advantages of excellent sealing effect and the like, the bearing and the oil seal have high concentricity, and the sealing effect is easy to detect.
Description
Technical field
The utility model relates to a kind of hermetically-sealed construction of motor shaft, belongs to the technical field of the machinery of motor.
Technical background
Isolate for step between the bearing pedestal of motor shaft and oil seal seat, its bearing pedestal and oil seal seat be processing respectively usually, causes both concentricitys relatively poor like this, cause the non-constant of its sealing effectiveness.Simultaneously, the state of oil sealing sealing can't be detected because bearing cooperates with bearing pedestal better in motor assembling back, is unfavorable for the sealing quality inspection before product uses.
Summary of the invention
The utility model purpose is to provide a kind of motor shaft hermetically-sealed construction, solved that the sealing effectiveness that prior art exists is poor, low with the motor coaxle degree, tightness is difficult for problems such as detection.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs:
A kind of motor shaft hermetically-sealed construction, comprise shaft, end cap, shaft stretches out by the centre bore of end cap, inside at end cap is provided with oil sealing, it is characterized in that being provided with in the end cap packing ring of bearing pedestal and oil seal seat and barrier bearing pedestal and oil seal seat, be respectively arranged with oil sealing and bearing in described bearing pedestal and the oil seal seat.
Bearing pedestal in the end cap and oil seal seat be by packing ring barrier rather than original end cap ledge structure, but such technical scheme make bearing pedestal of the present utility model and oil seal seat this take integral body to process, so can guarantee the concentricity of bearing pedestal and oil seal seat.Only packing ring need be placed between bearing and the oil sealing during assembling and get final product.
In order to reach better effect, the utility model packing ring preferably copper packing ring.
As preferably, be provided with circlip between described packing ring and bearing.The preferred circlip for hole of back-up ring is set between packing ring and the bearing.
As preferably, described bearing pedestal inwall offers the half-turn groove, and the circlip opening part is located in half-turn groove position.
Inwall at bearing pedestal offers the half-turn groove, makes motor assembling finish the back is useful on detection in the outside of bearing half-turn groove, if oil sealing is not fully, the air-flow that the half-turn groove outside bearing passes through just can detect.
As preferably, the bearing pedestal inwall offers ring recess, is provided with circlip in the ring recess, and described circlip radially embeds in the bearing pedestal.Back-up ring embeds its effect of easier performance in the bearing pedestal.
As preferably, the utility model adopts multiple oil sealing, and two or more oil sealing is set in oil seal seat.
Therefore, the concentricity height, good sealing effect, sealing effectiveness that the utlity model has bearing and oil sealing characteristics such as detection easily.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings 2, the technical solution of the utility model is described in further detail.
Embodiment 1: as shown in Figure 2, a kind of motor shaft hermetically-sealed construction, comprise shaft 2, front end housing 1, shaft 2 stretches out by the centre bore of front end housing, be provided with oil sealing 6 in the inside of front end housing 1, the outside of front end housing 1 is provided with connected body 3, it is characterized in that front end housing 1 is provided with the bulge loop 9 that is used to block connected body, and connected body 3 is connected on the outer surface of front end housing by bulge loop 9.Be inserted with Elastic clamping plate 4 between described bulge loop 9 and connected body.The radial outer end of clamping plate 4 deviates from the connected body direction and turns up, described clamping plate 4 are chuck, radially opposite position at connected body 3 and front end housing 1 offers a seal groove, be equiped with sealing ring 8 in the seal groove, have another seal groove on the radial end face of connected body 3 and front end housing, it also is equiped with a sealing ring 7.While the utility model, end cap in bearing pedestal and oil seal seat adopt a cutter to make, behind two oil sealings 6 that fitting tight is used, the copper packing ring 11 of packing into is isolated bearing and oil sealing, behind the packing ring 11 of packing into, reinstall flexible back-up ring 10, flexible back-up ring 10 embeds in the bearing pedestals, and flexible back-up ring 10 is between bearing 12 and the packing ring 11, at a side shaft of back-up ring to offering half-turn groove 14.Barrier between the utility model cancellation oil seal seat and bearing pedestal, adopt Spring Clip, bearing pedestal and oil seal seat can be processed by a cutter, have guaranteed concentricity requirement and have added the perpendicularity requirement of having assembled when copper washer has guaranteed oil sealing in the collar outer end, have improved the effect of sealing greatly.
Claims (7)
