Lubricant oil cooling apparatus for power transmission apparatus

Abstract

A lubricant oil cooling apparatus 1 , which lubricates a speed reducer 10 transmitting and outputting the power of a motor 11 , includes first supporting members 5 b , a bed 5 supporting the motor 11 , and a cooling pipe 4 which penetrates the first supporting members 5 b while contacting them and constitutes a part of piles supplying the lubricant oil to the speed reducer 10.

1 . A lubricant oil cooling apparatus for a power transmission apparatus transmitting and outputting power of a motor, the lubricant oil cooling lubricant oil lubricating the power transmission apparatus and comprising:
 a bed which includes a first supporting member and supports the motor; and   a cooling pipe which penetrates the first supporting member while contacting the first supporting member and constitutes a part of a pipe which supplies the lubricant oil to the power transmission apparatus.   
     
     
         2 . The lubricant oil cooling apparatus according to  claim 1 , wherein, the bed includes:
 a fixing plate which fixes the motor and is supported by the first supporting member in a direction in which the motor is fixed; and   a second supporting member which has a surface with which the first supporting member is in contact and supports the fixing plate together with the first supporting member.   
     
     
         3 . The lubricant oil cooling apparatus according to  claim 1 , further comprising a casing which houses the power transmission apparatus along with the lubricant oil, wherein,
 the cooling pipe is arranged to be lower than a height position of an oil level of the lubricant oil in the casing.   
     
     
         4 . The lubricant oil cooling apparatus according to  claim 2 , further comprising a casing which houses the power transmission apparatus along with the lubricant oil, wherein,
 the cooling pipe is arranged to be lower than a height position of an oil level of the lubricant oil in the casing.
