DETAILED DESCRIPTION
[0011] The preferred embodiments of the present application will be described below with reference to the drawings. Those skilled in the art will understand that these embodiments are only used to explain the technical principles of the present application, and are not intended to limit the protection scope of the present application.
[0012] The utility model provides a novel both ends support bearing housing structure, including bearing housing 16, bearing 15 and shaft 12 are installed in bearing housing 16, oil ring sleeve 13, stop washer 11 and round nut 10 are installed in sequence on the shaft 12 and located bearing 15 one side, dustproof shaft sleeve 21 and bearing gland 19 are installed on the other side, bearing gland 19 is fixed on bearing housing 16 through gland nut 17 and gland bolt 18, end cover 8 is installed to bearing housing 16 one side through end cover bolt 6, oil tank cover 3 is installed to bearing housing 16 below through oil tank cover bolt 2, oil tank cover 3 is installed oil drain plug 4 on, oil slinger 14 is installed on oil ring sleeve 13, dustproof disc 20 is installed on dustproof shaft sleeve 21, oil window 9 is also set up on bearing housing 16, heat pipe 5 is also installed to oil tank cover 3, even distribution has inner fin 7 in bearing housing 16 in heat pipe 5 one end, even distribution has outer fin 1 on bearing housing 16 outside the other end, and heat dissipation is carried out through outer fin 1, heat pipe 5 and inner fin 7, so that bearing housing need not external cooling water, can guarantee bearing temperature stability.
[0013] Although the present application has been described with reference to the preferred embodiments, various modifications can be made to it without departing from the scope of the present application, and equivalent substitutions can be made to the components thereof, especially, as long as there is no structural conflict, each technical feature mentioned in each embodiment can be combined in any way.
