Abstract
The utility model discloses a kind of modified model speed reducer, belong to speed reducer technical field, mainly solve the problem that existing speed reducer oil temperature is high, its technological scheme is provided with oil inlet hole in the input a set of cups side of speed reducer, and opposite side is provided with spill port, the outside of oil inlet hole is connected with swab case, inner side is communicated in input cavity, and during speed reducer work, swab case is positioned at deceleration box, be communicated with deceleration box outside spill port, inside spill port be arranged on the oil-return groove that input end covers and be communicated with; The utility model by being provided with oil inlet hole and spill port on input a set of cups, the lubricant oil in deceleration box can be made fully to circulate between deceleration box and input cavity under the stirring of train of reduction gears, usually because input a set of cups wall thickness is thin compared with deceleration box wall thickness, like this, lubricant oil after flowing is more convenient lowers the temperature on input a set of cups, contributes to the control of the inner overall oil temperature of speed reducer.
Description
Technical field
The utility model relates to a kind of speed reducer, is specially a kind of speed reducer that effectively can reduce oil temperature.
Background technique
My company is that the first generation speed reducer that certain client produces delivers to customer to use rear discovery, in summer high temperature season, the temperature on speed reducer surface is usually more than 80 DEG C, even sometimes also more than 90 DEG C, high oil temperature exacerbates the oil ageing of speed reducer inside, oil viscosity is sharply declined, be not easy between gear pair to form oil film, gear anomalies is caused to be worn and torn, inner bearing and oil sealing component life also can shorten, and the inordinate wear of gear can cause oil temperature to raise, vicious circle like this, make equipment Rapid Damage, in addition, because input cavity and velocity-reducing chamber adopt the sealing configuration closed, the grease lubrication that input cavity adopts, when the disappearance of lubricating grease and aging, due to the inside of input cavity cannot be observed in time, add after lubricating grease just needs shutdown and speed reducer is disassembled, speed reducer regular maintenance is inconvenient, therefore, be badly in need of being improved solution for this technical problem.
Model utility content
The utility model is for above-mentioned technical problem, propose a kind of speed reducer of improved structure, this speed reducer is mainly improved primary speed-down chamber, needs to tear machine open, the technical problem of speed reducer regular maintenance inconvenience during to solve reducing speed now machine high oil temperature, interpolation lubricating grease.
In order to realize final purpose of the present utility model, intend adopting following technology:
A kind of modified model speed reducer, the deceleration box (5) comprising input a set of cups (1) and be fixed together with input a set of cups (1), wherein: input a set of cups (1) inside is in hollow shape, inner hollow forms the input cavity (3) of retarder, the two ends of input cavity (3), the arranged outside of input shaft has deep groove ball bearing (2) and roller bearing (4), and deceleration box (5) inside is provided with train of reduction gears (6), and improvements are:
Input a set of cups (1) side is provided with oil inlet hole (11), opposite side is provided with spill port (14), the outside of described oil inlet hole (11) is connected with swab case (10), inner side is communicated in input cavity (3), during speed reducer work, swab case (10) is positioned at deceleration box (5), and described spill port (14) outside is communicated with deceleration box (5), inside spill port (14) be arranged on the oil-return groove (12) that input end covers and be communicated with;
Described input a set of cups (1) is outside, is positioned at spill port (14) side and is provided with oil stifled (13).
Further, for increasing lubricating oil flow effect: described oil inlet hole (11) is obliquely installed, and spill port (14) is horizontally disposed with.
Further, for remaining the good lubrication of bearing, described oil inlet hole (11) and spill port (14) are arranged in the both sides of deep groove ball bearing (2).
The beneficial effects of the utility model are:
1. the utility model is provided with oil inlet hole and spill port on input a set of cups, being arranged so that of oil inlet hole and spill port is communicated with between input cavity and deceleration box inside, like this, the deep groove ball bearing of input cavity inside can be lubricious by the lubricant oil of deceleration box inside, change input cavity internal bearings in the past and adopt the working method of grease lubrication, the problem overcome and change lubricating grease, safeguarded inconvenience.
2. by being provided with oil inlet hole and spill port on input a set of cups, the lubricant oil in deceleration box can be made fully to circulate between deceleration box and input cavity under the stirring of train of reduction gears, usually because input a set of cups wall thickness is thin compared with deceleration box wall thickness, like this, lubricant oil after flowing is more convenient lowers the temperature on input a set of cups, contributes to the control of the inner overall oil temperature of speed reducer.
3. input a set of cups lower end, oil circuit is provided with oil stifled, is blocked up the lubricant oil oil viscosity can checking speed reducer inside at any time by oil, by the observation of oil viscosity, lubricant oil can be known and whether lost efficacy, contribute to a control of oil change and speed reducer maintenance period.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the CONSTRUCTED SPECIFICATION figure of input cavity described in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 to Figure 2, a kind of modified model speed reducer, the deceleration box 5 comprising input a set of cups 1 and be fixed together with input a set of cups 1, wherein: input a set of cups 1 inside is in hollow shape, inner hollow forms the input cavity 3 of retarder, the two ends of input cavity 3, the arranged outside of input shaft has deep groove ball bearing 2 and roller bearing 4, deceleration box 5 inside is provided with train of reduction gears 6, wherein: input a set of cups 1 side is provided with oil inlet hole 11, opposite side is provided with spill port 14, the outside of described oil inlet hole 11 is connected with swab case 10, inner side is communicated in input cavity 3, during speed reducer work, swab case 10 is positioned at deceleration box 5, be communicated with deceleration box 5 outside described spill port 14, inside spill port 14 be arranged on the oil-return groove 12 that input end covers and be communicated with, described input a set of cups 1 is outside, be positioned at spill port 14 side and be provided with oil stifled 13.
During utility model works, because deceleration box 5 stores the lubricant oil for lubricating speed reducer, under the stirring of train of reduction gears 6, lubricant oil enters oil inlet hole 11 through swab case 10, finally deceleration box 5 is flowed back to again again through deep groove ball bearing 2, spill port 14, owing to forming loop between input cavity 3 and deceleration box 5, so the lubricant oil of deceleration box 5 just can fully flow, usually because input a set of cups wall thickness is thin compared with deceleration box wall thickness, like this, lubricant oil after flowing is more convenient lowers the temperature on input a set of cups, contributes to the control of the inner overall oil temperature of speed reducer.
