Abstract
The utility model discloses a motor rear end cover with a water cooling structure. The motor rear end cover consists of a flange plate, a fixed ring, rib plates and a bearing seat, one end of the flange plate is provided with the cylindrical fixed ring, the fixed ring is provided with a rear end cover water outlet interface and a rear end cover water inlet interface, the bearing seat, the rib plates and the fixed ring form a sealed rear end cover cooling empty chamber, and the rear end cover cooling empty chamber is communicated with the rear end cover water outlet interface and the rear end cover water inlet interface. The bearing seat is also provided with an internal threaded hole for mounting a grease nipple, facilitating filling of lubricating grease without a machine halt to lubricate a bearing. The motor rear end cover with a water cooling structure is reasonable in design and simple in structure, a rear cover plate, a seal ring and a fastener needn't be additionally arranged, the cost is saved, the sealing is reliable, the service life is long, the cooling effects are good, and the rear end cover bearing can be effectively protected. The motor rear end cover with a water cooling structure is suitable for being used together with a drive motor having a water cooling structure for a roller way.
Description
Technical field
The utility model relates to the gear reduction machine field, specifically a kind of back end cover for motor of water-cooling structure.
Background technology
Existing for metallurgy industry roller-way drive motors; owing to be in frequent starting under the condition of high temperature, braking and forward and backward operation for a long time; therefore, use the metallurgy of standard can't solve the fatal destruction that the heat conduction causes with frequency-conversion and speed-regulation motor, through regular meeting the situation that motor is burnt out takes place.Usually adopt the cooling space that is provided for the circulation cycle cooling water in motor front end housing inside at present, the affixed front shroud in the outside of front end housing, be provided with sealing ring between front shroud and the front end housing, and in motor rear bearing retaining outer end fan blade is housed, at rear end cap the fan housing that the protection fan blade is used is housed, to strengthen the cooling effect to motor rear end, this method is apparent in view to motor front end housing cooling effect, but when running into more the bad working environments condition, because long term high temperature operation, sealing ring can aggravate aging distortion, make the recirculated cooling water of front end housing inside occur leaking outside, influence the front end housing cooling effect, simultaneously, rear end cap cools off by fan blade and does not also satisfy working condition requirement, finally also can cause motor to be burnt out.
The utility model content
At the problems referred to above, the technical problem that the utility model quasi-solution is determined is for metallurgy industry provides a kind of back end cover for motor that seals the water-cooling structure of reliable, good cooling results, to guarantee motor reliable and stable work under the long term high temperature operating condition.
For achieving the above object, the utility model is by the following technical solutions: the back end cover for motor of water-cooling structure, it comprises ring flange, described ring flange inside has through hole, one end has the seam face, the other end is equipped with the columnar retainer plate of tool, described retainer plate is provided with the rear end cap water outlet interface with internal thread hole and has the rear end cap water inlet interface of internal thread hole, the gusset that has endoporus is equipped with at described retainer plate inner chamber two ends, be with bearing pedestal in the described gusset endoporus, described bearing pedestal and gusset, retainer plate surrounds the rear end cap cooling cavity of a sealing, described rear end cap cooling cavity and rear end cap water outlet interface, rear end cap water inlet interface is connected.
As the further of technique scheme improved and replenish, the utility model is taked following technical measures:
The back end cover for motor of above-mentioned water-cooling structure, described bearing pedestal inside is provided with dead eye, and the axis part in the outside of bearing pedestal is provided with internal thread hole.
The back end cover for motor of above-mentioned water-cooling structure also is provided with the installing hole of 6 circumference uniform distributions on the described ring flange.
The back end cover for motor of above-mentioned water-cooling structure also is provided with the fixing hole of 3 circumference uniform distributions on the described bearing pedestal.
The beneficial effects of the utility model are: the rear end cap cooling cavity that bearing pedestal and gusset, retainer plate is surrounded a sealing, described rear end cap cooling cavity is connected with rear end cap water outlet interface, rear end cap water inlet interface, need not to set up back shroud, sealing ring and securing member, it is good to have favorable cooling effect, the cost-saving, sealing is reliable, can effectively protect the rear end cap bearing; Simultaneously, on bearing pedestal, also be provided with the internal thread hole that grease nipple is installed, so that conveniently not shutting down grease up comes lubricating bearings.
The utility model is reasonable in design, and is simple in structure, and sealing is reliable, good cooling results, and long service life is applicable to the roller-way supporting use of drive motors of water-cooling structure.
