Abstract
Buffer gear in the open road sweeper round brush cylinder transmission device of the utility model, described buffer gear comprises sleeve, bounce cylinder and buffering sprocket wheel, described bounce cylinder bottom is fixed on the vehicle frame of road sweeper, described jacket casing is located on the push rod of bounce cylinder, the top of sleeve is provided with bearing, described buffering sprocket wheel is located on bearing, and the chain cushioning in sprocket wheel and described round brush cylinder transmission device is connected with a joggle.The utility model is not only simple in structure, and the impact being subject to can effectively avoid chain, head sprocket and output shaft of gear-box to brake because of road sweeper time, thereby raising chain-drive mechanism that can be effectively and the application life of output shaft of gear-box.
Description
Technical field
The utility model relates to road sweeper field, relates in particular to the buffer gear in road sweeper round brush cylinder transmission device.
Background technology
At present, the round brush cylinder on road sweeper is to drive round brush cylinder to rotate by the output shaft of gearbox by chain-drive mechanism, thereby realizes ground surface round brush and cleaning.Road sweeper, in the process of advancing, needs brake unavoidably.In the time that road sweeper brakes, head sprocket is in static, and there is proal inertia in round brush cylinder, therefore there is the trend of rotation forward from sprocket wheel, thereby impact the output shaft of head sprocket and gearbox by chain, be subject to for a long time such impact, chain, head sprocket and output shaft of gear-box all easily produce and damage.
Summary of the invention
The purpose of this utility model is to provide the buffer gear in a kind of road sweeper round brush cylinder transmission device simple in structure, the impact force producing when this buffer gear can brake road sweeper cushions, and improves and drives the chain-drive mechanism of round brush cylinder rotation and the application life of output shaft of gear-box.
For achieving the above object, the utility model is by the following technical solutions:
Described buffer gear comprises sleeve, bounce cylinder and buffering sprocket wheel, described bounce cylinder bottom is fixed on the vehicle frame of road sweeper, described jacket casing is located on the push rod of bounce cylinder, the top of sleeve is provided with bearing, described buffering sprocket wheel is located on bearing, and the chain cushioning in sprocket wheel and described round brush cylinder transmission device is connected with a joggle.
Described buffer gear also comprises guide rail, and the bottom of described guide rail is fixed on the vehicle frame of road sweeper, and is positioned at a side of sleeve, and the sidewall of the corresponding guide rail of described sleeve is provided with guide pad, and described guide pad and guide rail are slidably connected.
Described guide rail is parallel with bounce cylinder.
The utility model adopts above technical scheme, in the time that road sweeper brakes in traveling process, because existing the impact force that proal inertia produces, round brush cylinder can press down buffering sprocket wheel by chain, and be sequentially finally passed to bounce cylinder by supporting seat, sleeve, bounce cylinder is subject to downforce, then downforce is cushioned and discharges.The utility model is not only simple in structure, and the impact being subject to can effectively avoid chain, head sprocket and output shaft of gear-box to brake because of road sweeper time, thereby raising chain-drive mechanism that can be effectively and the application life of output shaft of gear-box.
Brief description of the drawings
below in conjunction with the drawings and specific embodiments, the utility model is described in further details:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, buffer gear in the utility model road sweeper round brush cylinder transmission device, road sweeper round brush cylinder transmission device comprises head sprocket 3, from sprocket wheel 4 and chain 5, head sprocket 3 is located on the output shaft of road sweeper gearbox 7, be located at the axle head of round brush cylinder 2 from sprocket wheel 4, chain 5 is connected with a joggle with head sprocket 3 with from sprocket wheel 4 respectively; Buffer gear 6 of the present utility model is provided in a side of head sprocket 3 and between sprocket wheel 4, described buffer gear 6 comprises sleeve 61, bounce cylinder 62 and buffering sprocket wheel 63, described bounce cylinder 62 bottoms are fixed on the vehicle frame 1 of road sweeper, described sleeve 61 is set on the push rod of bounce cylinder 62, the top of sleeve 61 is provided with bearing 64, described buffering sprocket wheel 63 is located on bearing 64, and buffering sprocket wheel 63 is connected with a joggle with the chain 5 in described round brush cylinder transmission device.
Described buffer gear 6 also comprises guide rail 65, and the bottom of described guide rail 65 is fixed on the vehicle frame 1 of road sweeper, and is positioned at a side of sleeve 61, and the sidewall of the corresponding guide rail 65 of described sleeve 61 is provided with guide pad 66, and described guide pad 66 is slidably connected with guide rail 65.In the time that sleeve 61 is subject to downforce and moves downward, sleeve 61 can move downward along guide rail 65, impact force can be changed into like this to a downforce along guide rail 65 directions, can impact force be transferred on bounce cylinder 62 more concentrated, more swimmingly like this, thereby allow impact force cushion and to discharge more thoroughly, but also can improve the application life of bounce cylinder 62.
Described guide rail 65 is parallel with bounce cylinder 62.
Operating principle of the present utility model: in the time that road sweeper brakes in traveling process, because existing the impact force that proal inertia produces, round brush cylinder 2 can press down buffering sprocket wheel 63 by chain 5, and be sequentially finally passed to bounce cylinder 62 by supporting seat 64, sleeve 61, bounce cylinder 62 is subject to downforce, then downforce cushioned and discharge, the impact being subject to while so just having avoided chain 5, head sprocket 3 and gearbox 7 output shafts to brake because of road sweeper, thereby raising chain-drive mechanism that can be effectively and the application life of gearbox 7 output shafts.
