In addition, in order to ensure the safety and high efficiency of the work, the speed reducer needs to be checked regularly, and the power supply needs to be cut off during the checking, and the checking can be carried out only after the speed reducer is cooled to a proper temperature. Because the cooling time of speed reducer is longer in the reality, lead to the maintenance time overlength, delay operating time, it just inspects to appear that operating personnel waits that the speed reducer cools off completely easily, leads to detecting inaccurately, influences machine work efficiency, shortens the life of speed reducer, influences production safety even.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a technical problem that will solve has overcome the defect among the prior art, provides a simple easy implementation from large-scale speed reducer shell of taking cooling circulation system.
In order to achieve the above object, the utility model provides a following technical scheme: a large-scale speed reducer shell with a cooling circulation system comprises a shell, a coolant channel, a coolant storage chamber, a circulation pump, a control valve, a coolant input port, a coolant output port and a speed reducer internal mechanism.
Further, a first coolant channel and a second coolant channel in the coolant channels are connected by a first branch channel, a first coolant channel, a second coolant channel, a third coolant channel and the like in the coolant channels are connected by a first branch channel and a second branch channel, and the coolant channels are distributed in a continuous approximate shape of a Chinese character 'mu' in the housing.
Further, the cross section of the coolant channel may be circular, square, or rectangular.
Further, the coolant inlet and the coolant outlet of a first coolant passage among the coolant passages are connected to the coolant reservoir.
Further, the circulation pump is provided at the coolant input port of the first coolant passage.
Further, the control valves are respectively disposed on the first branch channel and the second branch channel at both ends near the coolant input port and the coolant output port.
Compared with the prior art, the beneficial effects of the utility model are that: reasonable in design, easy to carry out. Coolant channel directly sets up in the inside of speed reducer shell, with shell integrated into one piece seamless connection, such design can be in the setting of accomplishing coolant channel under the condition that does not set up coolant channel in addition, because any passageway that adds can't guarantee in addition can not cause the damage to the speed reducer shell, and the passageway that adds is inside owing to being located the speed reducer, overhaul the inconvenience that also can be very, be unfavorable for maintenance at ordinary times, and form coolant channel direct with the integrative casting of speed reducer shell, all problems of external equipment have been avoided. The continuous distribution of the coolant channels similar to the shape of a Chinese character 'mu' can bring the effect of reducing the temperature of the speed reducer to the largest area. The control valves respectively positioned on the first branch channels close to the two ends of the coolant input port and the coolant output port can be opened according to actual conditions, when the working temperature of the speed reducer is only required to be controlled, the control valves can be closed, the coolant channels through which the coolant flows are reduced, and the function of controlling the temperature of the working environment is only exerted; when the speed reducer needs to replace lubricating oil, the control valve can be opened, so that the coolant flows through all the coolant channels, and the speed reducer is comprehensively cooled.
