Description
Technical field
The utility model relates to the motor water seepage-proof tech, specifically a kind of end cap water-cooled machine anti-leakage structure.
Background technology
The end cap water-cooled machine is widely used as the motor of coal-winning machine, and its water leakage fault rate is directly connected to its reliability, and then is related to the safe operation of coal-winning machine.Particularly, in case the cooling water in its cooling water channel enters motor internal, just can affect the safe operation of motor, and then affect the safe operation of coal-winning machine, bring great potential safety hazard.Therefore, for avoiding above-mentioned potential safety hazard, usually between the end cap of end cap water-cooled machine and support, anti-leakage structure is set.As shown in Figure 1, existing end cap water-cooled machine anti-leakage structure comprises end cap, support and O RunddichtringO.Wherein, end cap inside is provided with the end cap cooling water channel, and the end cap cooling water channel connects the inner side end of end cap.Base inner is provided with the support cooling water channel, and the support cooling water channel connects the end face of support.The inner side end of end cap and the end face of support are close to, and the O RunddichtringO is installed between the end face of the inner side end of end cap and support.The end cap cooling water channel is communicated with the support cooling water channel.The shortcoming of existing end cap water-cooled machine anti-leakage structure is: one, the sealing of cooling water channel too relies on end face and is close to, thereby the flatness of the end face of the inner side end of end cap, support is had relatively high expectations, and causes difficulty of processing large.Two, the sealing of cooling water channel too relies on end face and is close to, thus when assembling the end face of inner side end and the support of end cap must be parallel, be adjacent to, careless slightly just might causing leaks, and causes the quality of motors requirement high.Three, the sealing of cooling water channel too relies on the O RunddichtringO, because condition of work is extremely abominable under the coal mine, so that sealing ring very easily wears out, thereby causes sealing effectiveness very easily to be lost.Based on this, be necessary to invent a kind of brand-new end cap water-cooled machine anti-leakage structure, with solve existing end cap water-cooled machine anti-leakage structure difficulty of processing large, to the problem of high, the easy loss of seal effect of quality of motors requirement.
Summary of the invention
The utility model for solve existing end cap water-cooled machine anti-leakage structure difficulty of processing large, to the problem of high, the easy loss of seal effect of quality of motors requirement, a kind of end cap water-cooled machine anti-leakage structure is provided.
The utility model is to adopt following technical scheme to realize: end cap water-cooled machine anti-leakage structure comprises end cap, support and O RunddichtringO; End cap inside is provided with the end cap cooling water channel, and the end cap cooling water channel connects the inner side end of end cap; Base inner is provided with the support cooling water channel, and the support cooling water channel connects the end face of support; The inner side end of end cap is the stairstepping end face, and the inner side end outer ring of end cap exceeds the inner side end inner ring of end cap; The end face of support is the stairstepping end face, and the end face outer ring of support exceeds the end face inner ring of support; The inner side end outer ring of end cap and the end face outer ring of support are close to, and the O RunddichtringO is installed between the end face outer ring of the inner side end outer ring of end cap and support; Be provided with connecting water pipe between the inner side end inner ring of end cap and the end face inner ring of support; The connecting water pipe front portion is socketed in the end cap cooling water channel, and connecting water pipe anterior with the end cap cooling water channel between cooperate for slight interference; The front end end face of connecting water pipe and the inner side end inner ring of end cap are close to; The connecting water pipe rear sleeve is connected in the support cooling water channel, and is matched in clearance between connecting water pipe rear portion and the support cooling water channel; Between the rear end end face of connecting water pipe and the end face inner ring of support sealing gasket is installed; Tube chamber by connecting water pipe between end cap cooling water channel and the support cooling water channel is communicated with.
During work, all pass into cooling water in end cap cooling water channel, support cooling water channel, the connecting water pipe.For slight interference cooperates, prevented that thoroughly cooling water from spilling between end cap and connecting water pipe between end cap and the connecting water pipe.Sealing gasket, O RunddichtringO, that end face is close to common formation is multi-sealed, has prevented that effectively cooling water from spilling between support and connecting water pipe.Based on this process, compare with existing end cap water-cooled machine anti-leakage structure, end cap water-cooled machine anti-leakage structure described in the utility model no longer only relies on end face to be close to the O RunddichtringO cooling water channel is sealed, but be close to jointly by slight interference cooperation, sealing gasket, O RunddichtringO, end face cooling water channel is sealed.Therefore, end cap water-cooled machine anti-leakage structure described in the utility model has following advantage: one, the sealing of cooling water channel no longer too relies on end face and is close to, thereby reduced the flatness requirement of the end face of inner side end to end cap, support, reduced thus difficulty of processing.Two, the sealing of cooling water channel no longer too relies on end face and is close to, thereby has reduced requirement parallel to end face when assembling, that be adjacent to, has reduced thus the quality of motors requirement.Three, the sealing of cooling water channel no longer too relies on the O RunddichtringO, even thereby the O RunddichtringO occur agingly, slight interference cooperates, sealing gasket still can continue to play sealing function, thus so that sealing effectiveness is difficult for forfeiture.In sum, end cap water-cooled machine anti-leakage structure described in the utility model is based on brand new, efficiently solve existing end cap water-cooled machine anti-leakage structure difficulty of processing large, to the problem of high, the easy loss of seal effect of quality of motors requirement, be down to the water leakage fault rate of end cap water-cooled machine minimum thus, strong guarantee the safe operation of coal-winning machine, effectively avoided potential safety hazard.
The utility model efficiently solve existing end cap water-cooled machine anti-leakage structure difficulty of processing large, to the problem of high, the easy loss of seal effect of quality of motors requirement, be applicable to the end cap water-cooled machine.
