Abstract
The invention relates to a bearing box with a heat preservation device, which comprises a bearing box, bearings, a bearing gland and a shaft, wherein the bearings are arranged on the left end surface and the right end surface of the bearing box, the shaft is supported on the bearing box in a penetrating manner through the bearings, the bearing gland is arranged on the outer side of each bearing, a heat preservation sleeve is sleeved on the bearing box, and the heat preservation sleeve comprises an annular clamping cavity, and a water inlet pipe and a water outlet pipe which are communicated with the annular clamping cavity.
Description
Technical Field
The invention relates to the field of bearing boxes, in particular to a bearing box with a heat preservation device.
Background
When the bearing box is in a high-temperature environment and pumps high-temperature media, the temperature rise of lubricating oil of the bearing box can be caused due to the heat-conducting property of the transmission shaft. The bearing works excessively for a long time, the quality of lubricating oil is changed, the performance of the bearing is reduced, and finally the whole device is damaged; when the bearing box works in a low-temperature environment, lubricating oil of the bearing box is easy to condense due to low temperature, so that the lubricating effect is influenced.
Disclosure of Invention
The invention provides a bearing box with a heat preservation device, which aims to solve the problems of overheating of the bearing box or condensation of lubricating oil in the prior art.
The technical scheme adopted by the invention is as follows:
the bearing box with the heat preservation device comprises a bearing box body, a bearing gland and a shaft, wherein the bearing is arranged on the left end face and the right end face of the bearing box body, the shaft penetrates through the bearing and is supported in the bearing box body, the bearing gland is arranged on the outer side of the bearing, and a heat preservation sleeve is sleeved on the bearing box body.
Furthermore, the heat preservation cover includes that annular presss from both sides the chamber and with the inlet tube and the outlet pipe of annular clamp chamber UNICOM.
Furthermore, a baffle plate for separating the cavity is arranged in the annular clamping cavity, and the water inlet pipe and the water outlet pipe are arranged on two sides of the baffle plate.
After the technical scheme is adopted, the invention has the beneficial effects that:
(1) the heat insulation sleeve with the annular clamping cavity is cast outside the bearing box by utilizing an integral casting design, cooling water is introduced into the annular clamping cavity to carry out heat insulation treatment on lubricating oil in the bearing box, and the problems of overheating or freezing of the bearing and the lubricating oil in the operation process are effectively avoided.
(2) The heat-insulation water tank is provided with a baffle for separating the cavity, the water inlet pipe and the water outlet pipe are coaxially arranged on two sides of the baffle, cold/hot water enters from the water inlet pipe on one side of the baffle and is discharged from the water outlet pipe on the other side of the baffle after the cold/hot water is blocked by the baffle around the annular cavity for a circle, the cold/hot water and the bearing box fully exchange heat, local heat exchange is avoided, and the heat-insulation effect is enhanced.
Drawings
FIG. 1 is a front view of the present invention;
FIG. 2 is a view A-A of the present invention.
In the figure: the bearing comprises a bearing gland 1, a bearing 2, a bearing box 3, a heat-insulating sleeve 4, a shaft 5, an annular clamping cavity 6, a water inlet pipe 7, a water outlet pipe 8 and a baffle plate 9.
Detailed Description
The following detailed description of embodiments of the invention is provided in conjunction with the accompanying drawings:
as shown in the figure, a take heat preservation device's bearing box includes bearing gland 1, bearing 2, bearing box 3, insulation cover 4, axle 5, annular double-layered chamber 6, inlet tube 7, outlet pipe 8 and baffle 9, the left and right sides of bearing box 3 is equipped with the dead eye respectively, and axle 5 runs through bearing in bearing box 3 through bearing 2, and the bearing 3 outside is sealed with bearing box 3 by bearing gland 1, the surface of bearing box 3 is through integral type casting shaping or has cup jointed insulation cover 4, form annular double-layered chamber 6 between insulation cover 4 and bearing box 3, be equipped with the baffle 9 that separates with annular double-layered chamber in the annular double-layered chamber 6, be equipped with inlet tube 7 and outlet pipe 8 with annular double-layered chamber 6 UNICOM on the insulation cover 4 of the both sides of baffle respectively.
When the bearing box 3 needs heat preservation treatment, cold water or hot water enters the annular clamping cavity 6 from the water inlet pipe 7, is blocked by the baffle 8, surrounds the annular clamping cavity for a circle, and is discharged from the outlet of the water outlet pipe 8 on the other side of the baffle, so that heat preservation circulation is completed.
Simple variations or modifications made without departing from the core of the invention fall within the scope of protection of the invention.
Claims (3)
1. The utility model provides a take heat preservation device's bearing box, includes bearing box, bearing gland and axle, the terminal surface is equipped with the bearing about the bearing box, the axle runs through the bearing in the bearing box through the bearing, and the outside of bearing is equipped with the bearing gland, its characterized in that, the cover has the insulation cover on the bearing box.
2. The bearing box with the thermal insulation device as claimed in claim 1, wherein the thermal insulation sleeve comprises an annular clamping cavity, and a water inlet pipe and a water outlet pipe which are communicated with the annular clamping cavity.
