Abstract
The invention relates to a direct connection type motor. The direct connection type motor comprises a front motor end cover and a motor shaft. The motor shaft is connected with the front motor end cover through a bearing, the center of the front motor end cover is conical around the motor shaft, an oil seal and an oil retainer are sequentially and coaxially installed on the outer side of the bearing from inside to outside, and a gap is reserved between the oil retainer and the oil seal. A screw for fixing the front motor end cover and a motor body is arranged at one end of the front motor end cover, the head of the screw is installed in a cavity of the front motor end cover, and the installed cavity is filled with sealant. The conical center of the front motor end cover can be effectively matched with the motor shaft and matched with a speed reducer smoothly; through guarantees of the oil retainer and the oil seal, jamming, oil leakage and the like of the motor shaft do not need to be worried in the operating process.
Description
Technical field
The present invention relates to a kind of direct-connected motor, be specifically related to a kind of motor of direct connection reducer.
Background technology
G series reducing motor (comprising cycloidal planetary gear speed reducer) has motor straight tape splicing to move the version of reductor running.Commercially the general way by adding a counter flange in the middle of reductor and motor realizes the docking of the two, although achieve connection, there is obvious defect: axial installation dimension is longer; Counter flange is foundry goods, mold, and the production cycle is longer, and cost increases; Will there be at least two bearings the inside of counter flange, also will process the coupling spindle that is played anastomosis, so in the limited inside of counter flange, space is just less, and area of dissipation is too little, and counter flange easily generates heat, and heat is higher.
Summary of the invention
The object of the present invention is to provide a kind of direct-connected motor, special by the end that motor is connected with decelerator, motor can be made directly to be connected with decelerator, not need coupling spindle and counter flange, cost can save 10 ~ 20%, more can shorten the delivery cycle in production.
For achieving the above object, the invention provides a kind of direct-connected motor, comprise motor front end cover and motor shaft, described motor shaft is connected with motor front end cover by a bearing, and motor front end cover centre is coniform around motor shaft, outside described bearing, successively an oil sealing and oil scraper ring are coaxially installed from inside to outside, between described oil scraper ring and described oil sealing, leave space; One end of described motor front end cover is provided with a screw fixed for motor front end cover and motor body, and the head of described screw is arranged in a cavity of motor front end cover, fills up fluid sealant in the described cavity after installation.Cone shape motor front end cover centre can effectively coordinate with motor shaft, matches smoothly with decelerator; By the guarantee of oil scraper ring, oil sealing, motor shaft is not worried in operation process, and the situations such as stuck and leakage of oil occur.
Further improvement of the present invention is: described bearing shaft is respectively equipped with the elastic washer suitable with bearing outside both ends of the surface, and bearing can effectively be fixed in end cap by elastic washer, and significant sealing affection, not easily produce and loosen and leakage of oil.
Further improvement of the present invention is: one end of described motor front end cover is provided with a breather plug, and protection oil sealing, strengthens the waterproof to motor, soiling protective.
The invention has the beneficial effects as follows: the end be connected with decelerator by motor is special, enable directly to match with decelerator, and protected by each link in motion process, can not the phenomenons such as leakage of oil be produced, cost-saving.
Accompanying drawing explanation
Fig. 1 represents the front view of the present embodiment;
Drawing reference numeral: 1-motor shaft, 2-oil scraper ring, 3-oil sealing, 4-bearing, 5-motor front end cover, 6-breather plug, 7-screw, 8-circlip for shaft, 9-circlip for hole.
Embodiment
In order to deepen the understanding of the present invention, below in conjunction with drawings and Examples, the present invention is described in further detail.
See accompanying drawing 1, the present invention proposes a kind of direct-connected motor, comprise motor front end cover 5 and motor shaft 2, described motor shaft 2 is connected with motor front end cover 5 by a bearing 4, and motor front end cover 5 centre is coniform around motor shaft 2, one oil sealing 3 and oil scraper ring 2 are coaxially installed successively from inside to outside outside described bearing 4, between described oil scraper ring 2 and described oil sealing 3, leave space; One end of described motor front end cover 5 is provided with a screw 7 fixed for motor front end cover 5 and motor body, the head of described screw 7 is arranged in a cavity of motor front end cover 5, fill up fluid sealant, good sealing effect in described cavity after installation, manufacturing process is simple.Cone shape motor front end cover 5 centre can effectively coordinate with motor shaft 1, matches smoothly with decelerator; By the guarantee of oil scraper ring 2, oil sealing 3, motor shaft 1 is not worried in operation process, and the situations such as stuck and leakage of oil occur.
The axle elastic washer 8 suitable with bearing 4 and circlip for hole 9 is respectively equipped with outside the axial both ends of the surface of described bearing 4.Circlip on the one hand can rigid bearing, make axial location precisely outside, also play sealing function, prevent greasy dirt etc. from entering.One end of described motor front end cover 5 is provided with a breather plug 6, and protection oil sealing 3, plays the waterproof to motor, soiling protective further.
The front end housing of motor carries out special by whole device, has both met electric machine structure requirement of strength, also meets speed reducer structure requirement of strength, motor can be made directly to be connected with decelerator, do not need coupling spindle and counter flange.Sealing structure is good, ensures oil-proof excessive, and water proof anti-soil.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure transformation utilizing specification of the present invention and accompanying drawing content to do; such as breather plug changes plug cock etc. into; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
